Hi picked up a AST 486DX2-66mt puter Trying to install win 95 , did the f disk created new part. formatted and cannot seem to get CD rom drive to work. just says Device name BANANA then no drives found aborting installation.. then Device driver not found , then No valid cd rom device drivers selected any help would be appreciated, have done this to a few puters but this one has me puzzled as its running the small floppy disk and the old larger one and then a cd rom under that Thanks allan
Your start-up disk/bootdisk does not have your cdrom driver on it.
If your using a Win 95 one, go here and download and install a Win 98 one. It should pick up your cdrom.
http://www.bootdisk.com
Murf,
Most of the boot disks on bootdisk.com use the /D:BANANA switch instead of the standard /D:MSCD001. So, it looks like he obtained his bootdisk there already.
Allan,
It looks like the CDROM driver in the CONFIG.SYS did not detect an ATAPI CDROM, hence the "No drives found, aborting installation." Of course, when the driver fails, MSCDEX.EXE will also fail.
What CDROM drive do you have? Perhaps it's a proprietary drive for which the bootdisks on bootdisk.com do not provide a driver. You may need to go to the website of the CDROM manufacturer and see if they have DOS drivers available. Certain Mitsumi and Panasonic drives use 40-pin cables to connect to their controller, but are not IDE/ATAPI. And Sony had some drives that used a 34-pin connector (but don't hook them up to the floppy controller.)
Murf i downloaded the win 98 boot disk and tried it and all i get is invalid system disk mssg what am i doing wrong ??
thanks allan
The CD Rom is a sony CDU33A-01 with the small 34 pin connector and its going by ribbon cable to the sound card ??? i dont know it's just not normal , probably why i got it cheap any more idea's
thx allan
Do I know my old-school CD-ROM drives, or what? :)
You're going to need to get 173a.exe, extract it, copy SLCD.SYS to your boot floppy (the one you were using before, not the new one you downloaded, although that's easy enough to get to work), and then add the following line to the CONFIG.SYS on that boot floppy:
I tried getting the file from Sony, but was told I "may" be able to get the file from a Sony site that no longer exists, and that the drive was no longer supported. So, I scrounged around and found it at Alfa Computers Support Page.Code:DEVICE=A:\SLCD.SYS /D:BANANA /B:340 /M:P /V /C
I'm not sure why Sony doesn't have drivers for all their products on their page, though... does kind of a disservice to people who own their products.
Hi Well i did what u said and changed config.sys and now the puter says unrecognized command any ideas why ??
thx allan
Well did some more researching and came up with the cd is definately a sony cdu-33a and it is hooked up to a sb16 creative labs sound card by ribbon cable 34 pin, fcc id # on the sound card shows ibact-sb16sony but the card also has creative labs written on the edge ok this is a new one for me to figure out ?? just how is a sound card going to drive a cd-rom ?? any ideas at all on how to get this thing to operate the cd so i can install windows
Really appreciate your help thx allan
Not only did you change CONFIG.SYS, but you also copied the file SLCD.SYS to the boot floppy? That's an important step-- if you're going to tell CONFIG.SYS a file can be loaded, make sure the file is available. Again, once you download 173a.exe, you must run that file and it will expand into several more files, one of which is SLCD.SYS. This file needs to be on your boot disk for the DEVICE=A:\SLCD.SYS /D:BANANA /B:340 /M:P /V /C line to work.Quote:

Chances are your sound card is a CT2230 (look on the upper edge of the card), just like one I have in an older system. It may have 3 different CDROM controller connectors... This is how they did it back in '93....
Also, don't worry about installing drivers for the audio card itself. The CD-ROM should work when connected to that card whether the sound drivers are installed or not.
Well gentlemen i think im getting closer to getting this puter working But!!did everything step by step as told and finally got the slcd to show up but mssg at boot is as follows
SONY SLCD DEVICE DRIVER VERSION 1.71A
NO DRIVES ARE ATTACHED..DRIVES ARE POWERED DOWN,
OR COMMUNICATION FAILED
THE DEVICE DRIVER IS NOT INSTALLED
DEVICE DRIVER NOT FOUND 'BANANA'
NO VALID CDROM DEVICE DRIVERS SELECTED
Well thats the mssg but at least it's trying huh ??Also since i got this puter i forgot to mention that the cdrom light is always on no matter what im doing even using a:\ drive it's on ???
thank you so much for the help so far "Allan"
My sb16 card has the #'s ct1790 on hope this helps
Much better-- the driver is attempting to load!
It's been ages since I messed with that particular drive (I don't have one anymore), but I think the light on that drive was always on, and just changed color when reading...
You may have to experiment with the /B: switch on the driver line, to properly reference the base I/O of the interface on the card. /B:340 is the default for the Sony controllers, but I think I had to put /B:230 or /B:240 or /B:250 (somewhere around that range-- I know it wasn't /B:220 because that was the base I/O of the audio portion of the card itself. Maybe it had to be 10 higher than the base I/O of the sound card...)
Gentlemen Well a little success on this end I changed the switch to 230 and got the cdrom to work i just finished loading win 95 from my disk and have some more troubles puter says starting win 95 then goes to the win95 screen then kicks over to the command list saying windows did not finish loading and to select safe mode . i press enter for safe mode and the puter just keeps doing this over and over will not start in safe mode at all ???
Help this puter is a hair puller outer
thx allan
Kapwing! Getting closer!
Could be some hardware in there conflicting with something... What you could do is copy the \Win95 directory from the Windows 95 CD to the hard drive, then pull out any non-essential hardware, and retry the installation.
Quick and painless way (with Win95 CDROM in the tray):
- At the A:\> prompt, type: C: and press enter
- At the C:\> prompt, type: md \cabs and press enter
- Type cd \cabs and press enter
- Substituting the drive letter for the CDROM drive for X, type: copy /v X:\win95\*.* and press enter. You'll see filenames scroll by, and get a message eventually that some files were copied.
Now, shut down the computer and remove the sound card (you can leave the CDROM in the machine, just unhook the data cable from it or the sound card to make removing the sound card easier. If you have a modem, remove it, too.
Now boot from your floppy again, ignoring the messages about the CDROM, since, obviously, it's not hooked up anymore.
- At the A:\> prompt, type: C: and press enter
- At the C:\> prompt, type \cabs\setup and press enter.
Hopefully, the installation proceeds much more smoothly, and then you can troubleshoot reinstalling the sound card and CDROM once Windows is up and running.
hI FINALLY GET A CHANCE TO GET BACK AT THIS DARN PUTER
WORK, WORK ,GUESS WE ALL HAVE TO DO THAT .. JUST A SMALL QUESTION DO I HAVE TO FORMAT THE DRIVE,, BEFORE I TRY THE TAKE THE PUTER APART WAY TO INSTALL WINDOWS Ha Ha
THANKS ALLAN:) :)
NO
You already di, follow Alaricd advice, should install it. One of the reason to install from the Hard Drive, is that older cdrom's take too long to read during the install process and can hang up when trying to read ahead. Your hard drive is faster...
Hi Again did all the right things but the puter will not take the \cabs\setup Command all else went smoothly till this Help Again
thx allan
Try:
cd\cabs (hit <enter> key)
setup (hit <enter key>)
OK Back again got setup to run by just typing setup did the whole shebang and watched win load etc. it restarted the puter then bingo the fatal except blue screen appears saying
An exception OE has occuredat 0028:C002DDF6 in VxD VPICD(01)+000008B2. This was called from 0028:C002DD40 in VxD VPICD(01)+000007FC HELP!!!! Allan
turned puter off then on as no keys would do anything and got another blue mssg saying 0028:74001506 in VxD---,This was called from 0028:C0030E1C in VxD VPICD(01)_+000007FC
Gee What next thx allan
Well Restared again and all i got was a mssg saying While initilizing VXDLDR Windows protection error you have to restart your puter just said this on a black screen this time ??
allan
I've worked on many 486's and depending on the BIOS version, you may have to disable cache to load Windows 95 on it. Some of the older BIOS were not Y2K-corrected compatable and you can run into the problems your having.
Reboot and hit the DEL key to get into SETUP (CMOS), or watch the screen and it should tell you what key to use to get into it.
Once in there, find the entry under one of the menu items that says something about ANTI-VIRUS, if it is Enabled, Disable it and SAVE & EXIT and try loading Windows again.
If it is Disabled, then find the entry about Internal and External Cache.
Disable External Cache and SAVE & EXIT, re-install. It will take about twice as long to install.
If it installs OK, when done go back and re-enable the Cache.
I would also check the date, at the A:\> prompt type the following:
c:
date
If the current date does not come up, or it is 5-10 years old or in the futher, the BIOS on that machine may not be Y2K and you will have all kinds of problems trying to load Windows 95/
I'm off for the rest of the night, hope this helps.
Here is a trouble shooting page for Protection Errors.
http://support.microsoft.com/default...EN-US;q149962&
Good advice on the BIOS Anti-virus setting and disabling the caches-- but a really quick fix for the date thing (I guess by W2K you meant Y2K, I don't think a 486 is Windows 2000 compatible) is just to set the RTC in the BIOS to some date in 1995. Win95 will never be the wiser if you never attempt to set the correct date...Quote:

Well im back at it again tonight tried everything you said last post date and time are correct and cannot seem to find anything abt antivirus and the cache external does not seem to be changeble as it says for reference only when i try to do anything to it running AST MT BIO"S 1.09 anymore ideas i just keep getting the pretty blue screen all the time
thx allan
Ummmmmmmmmm, how about Windows 3.11 (or Windows for Workgroups 3.11) and Win32s?
ALARIC You just lost me What do you mean , im thinking probably cannot put win 95 on this stupid thing right???????????
And i do not even know where to ever get win 3.1
thx allan
You might look in your BIOS for an option for "PnP OS", but if you've already removed all the unnecessary hardware (leaving just RAM, a video card, and the hard drive), then this setting should probably be meaningless.
If there's a BIOS upgrade you can download for your motherboard, you might try that-- although it's a bit rare for a 486 to have a flashable BIOS.
Aside from those things, it's possible you have a system that won't be able to take Windows 95.
Really need your help now Alaric went to the ast site and it sent me to ARI Service.com and they have a whole list of bio's flashes for advantage puters and im totally lost could you please look for me at this list and see if anything there to help me again i have an AST ADVANTAGE 486 DX2-66MT RUNNING AST BIOS REL 1.09 I HAVE NO CLUE ABT HOW TO UPGRADE BIO'S BUT THE BIO'S ON THE PUTER HAS AN UPGRADE SECTION AND SAYS U NEED DISK TO DO IT HELP AND THANK YOU SO MUCH FOR YOUR HELPING ALL THIS TIME ALLAN
There are several close matches for your system listed in this file, but no exact matches. Using the wrong file can render the system unusable.
It's also possible your system has the latest BIOS, as I do find a listing for 516311.EXE Bravo/Advantage! BIOS v.1.09, which could be the BIOS you are already running.
You might try entering the part number of your machine on the System Information page-- it may help locate the specific file you need. Also, the file itself should contain a readme explaining how to properly flash the BIOS. Like ARI Service, I take no responsibility for any adverse effects of flashing your BIOS.
Ok another question ALARIC this puter has both floppy disks and the cdrom could the 5" floppy drive be causing troubles ?? just a thought when i was sitting there getting mad at it
also i found out thru ari by entering my machine # that the caches are controlled by jumpers does this help any external cache says 64/none jumpers 7/8 off 256kb jumpers 7/8 on whatever this means whole bunch of jumpers and switches you could play with if i knew what to do and if needed to do
thx allan
The floppy drive controller uses IRQ6, it's highly unlikely any other device would use that IRQ (it's been reserved for floppies since the original PC.)
A motherboard manual for the jumpers would sure come in handy. Perhaps one can be downloaded from ari-service.com...
Alaric i was just going thru all that stuff trying to find an option that you could use but i don't have a clue abt half of the stuff i was looking at i typed in my p/n of machine and it tells u everything p/n 501421-004 when and if you have time maybe you could look at this list and let me know if anything else we can do with this puter hate to let 1 get the best of us !!! again really appreciate the help will be on again tommorrw nite as it's late here and i have work early will be looking forward to your answer
Thanks Allan
Why do we seem to have so many problems trying to get win95 on a puter that was built in oct /94 i have a darius puter also that was built earlier than this and put win 95 on it with no problems, Is AST just a piece of junk or ???? sure would like to get this ast running win 95 it's trying so hard to load it but always hits a problem
thx allan
I agree with Vernon I think you have a bad stick of Ram and that is why you can't get Win 95 installed. If there is more then one stick try removing one or more and only leave one in, may have to swap out sticks until you find a bad one if it is bad memory.
Hi, I am new to VirtualDR, and I can't do any better that what has already been advised. I'll be watchin' this one. Great troubleshooting skills Murf & AlaricD. I'm just goin' down the line to see where I can help.
Well gentlemen i just read vernons post and went back to the puter and pulled all 4 ram out so i could get the #'s to purchase new ones and then just for the H of it when i put them back i switched the top 2 and then switched the bottom 2 well then i turned on the puter and stood way back Ha Ha well this darn thing loaded win 95 in safe mode advising me the master boot had been changed and then i went thru the ok's etc it restarted itself and now loads win 95 properly sooo? we all succeeded,
outsmarted another puter HuH thank you all so much for the help over the past week .. now i will try to see if it accepts a mouse/modem/printer/ etc so you just might be hearing from me again THANKS AGAIN
ALLANB:D :) :) :)
Apparantly the memory probably was not seated properly. Or the first two are OK and one of the last two are bad.
If you boot to SAFE MODE, Himem will test memory, its a fairly good memory tester.
Also here is a memory tester:
