Stupid SCO Questions

[SeaJay]

My apologies in advance for being Unix illiterate (I'm trying to learn though!).

OS: SCO Open Server 5.0.5

I'm having problems mounting a floppy disk. I can format it and look at the contents, but can't mount it so I can run a script. This is what I do/get:

#mount -r /dev/fd0 /mnt
mount: cannot stat '/dev/fd0': No such file or directory (error 2).

I check in /dev/ and see that there is an fd directory, but no fd0.
I checked on another machine and found fd and fd0, but fd0 doesn't appear to be a file or a directory.
Here's what the fd0 entry looks like on machine #2:
brw-rw-rw- 2 bin bin 2, 64 Jan 23 13:56 fd0

Is there an easy way to rebuild the missing fd0 device?

Thanks in advance,

Cj

If you look at your output from machine #2. let me eplain a couple things first.

brw-rw-rw- 2 bin bin 2, 64 Jan 23 13:56 fd0

The vert first character 'b', indicates that the nod is a block device. The numbers '2, 64' are the devices major and minor number, respectively, or their address and port number. In order to create the device file do"

mknod /dev/fd0 b 2 64

That's assuming that they are the same type of machine. On my machine the major and minor numbers for fd0 are '2, 0'.

Hope this helps. -mk

That worked! They were identical machines with identical hardware. Thanks for the education :-)

If you're feeling generous enough to answer one more....
Let's say I didn't have the identical machine handy? How would I determine the address & port numbers for the floppy drive?


Thanks again!

I'm not really sure. I know the major number will always be the same. As for the minor number, you may have to hunt and peck. Although, I think that depending on the OS, SCO, Linux, HPUX, within that OS the minor number will always be the same. I could be wrong, though. -mk

I could be wrong, though

But you're "righter" than I was, and I'm much further along now than I was yesterday :-)

Thanks again!

I'm glad I could help. Have fun. -mk
