IOS: Error: I/O Subsystem Driver Failed

[gemm]

Loaded Auto Route 2002 to pc to print off 2 maps. Uninstalled straight after. PC restarted reading: While initalizing device IOS: Error: An I/O Subsystem driver failed to load. Either a file in the .\iosubsys subdirectory is corrupt or the system is low on memory.

Has installing/removing Auto Route 2002 caused this problem and how do I fix it if I can???


Cheers

HI, Welcome to VRDR

If you just deleted Auto Route 2002 rather then uninstalling from ADD/REMOVE Programs in Control Panel, or used an uninstall program then YES.

Technically: This problem can occur when all memory below 1MB is allocated prior to initialization of Ios.vxd. Ios.vxd must allocate memory below 1MB for use as real-mode buffers. If Ios.vxd can't allocate this memory, it fails to load, which in turn causes Windows 95 to fail to boot.

Memory below 1MB is typically reserved for components that specifically request it. However, it is possible that Windows 95 will allocate all memory between 1MB and 16MB during initialization, forcing system DMA buffers (which must lie below 16MB) below 1MB, and therefore preventing Ios.vxd from being able to allocate memory below 1MB.

OK, so what how do I fix it:

This problem can be worked around by adjusting the maximum cache size allocated by Vcache.vxd. Vcache.vxd allocates an initial cache size that is no larger than 9MB. Setting the maximum cache size to less than 9MB also reduces the initial cache size, freeing up memory below 16MB and allowing Windows 95 to boot properly.

The maximum cache size is set by adding a "maxfilecache" line to the vcache section of System.ini. The following example shows what an entry in System.ini would look like to set the maximum cache size to 6MB:


[vcache]
maxfilecache=6144

OK, OK, How do I fix it already

I don't know - kidding:

Use a boot disk and get to the A:\prompt, once at the A:\> prompt type the following hitting <enter> key after each line:

c:
edit c:\windows\system.ini

This should bring up the system.ini file in a text editor (now you probably will not have a mousy).

Using the arrow keys scroll down until you see the following:

[vcache]

Change or type in if the line does not exist the following:

maxfilecache=6144

6144 should work...

(If [vcache] is not there then add it also), doesn't matter where within system.ini you put it.

Now FILE | SAVE, use your ALT key to open the top menu.

Reboot..

Thanx Murf!!

Auto Route was uninstalled through add/remove programs!

I wasn't asked if I wanted to delete any shared files or anything.
