I am trying to run linux on a 486. I want to use it as a server. The server has :
- 1 hard drive (a new one 60 gigs uf i remember corectly)
- 1 Ethernet card
- 1 cd-Rom + 1 floppy
- 1 video card
- VGA monitor
- 3 button serial mouse (no name)
- 32 megs of RAM
Here is my problem:
A few weeks ago I installed Red Hat 7.0. Everything was working fine except that I could not mount a flloppy (see : weird floppy problem (http://www.linuxquestions.org/questi...threadid=17923) ) About 2 days ago, I downloaded Red Hat 7.2 (From www.linuxiso.org) did a check sum on the 2 ISO, burn them. No problem so far. Installed linux (server configuration, deleting old partition). No problem so far. System restart, I log in. The problems started then.
Just to see I tried to mount a floppy. Still no luck (Have not yet tried mtools)
Then I wanted to start the X server using Window Maker.
Since the system told me window maker was not installed, I wanted to install it from the CD'S.
I used mount /mnt/cdrom
Response : mount: /dev/cdrom is not a valid block device
(I also tried mount -t iso9660 /dev/cdrom /mnt/cdrom , it gives me same message.)
I know the CD-Rom is working since I used it to install and it worker fine under 7.0.
Sorry for the really long post, but I want to be precise so I can get help ASAP. I mean I can't even see how well Linux would work since basic file acces function seem to malfunction!!
Thanks in advance!!

yeah you got the principle fine. /dev/cdrom is always (well.... 99% of the time) just a symlink to the device name.. hdb for you. it's only done for clarity. the chances are thatt cdrom actaully points to hdc. if you can mount it with the ide device name then you should re create the symlink (ln -sf /dev/hdb /dev/cdrom) and it all should be ok.
thanks for that DMR but that was just to be able to fully understand how Linux manages disk.
As for CD being on the secondary drive, I doubt it very much since it is a 486 we are talking about and the controler is a single IDE controller.
But thanks anyway for the post, now I thinks I fullly understand the naming convention for Linux.
By the way, tried reinstalling Linux, just to see. Still no luck, i'm thinking if going back to 7.0. Just to see if it is a problem with the way the new version handdle the IDE drives. Maybe something was change and it is not compatible with my old controller card??!?! Anyway, as Spock once said: " when you have illimanated all that is impossible all there is left is the improbable!!"
(just got to love this quote when working in computers!!)
I'll keep you posted on my progress.
Again, thanks everyone for the help!!

well i have kinda the same problem this is how i fixed it. Thou i have a dvd and it doesnt mount but i am sure you dont have a dvd drive so this should work on your cdroms. go into /etc/fstab then try this.
the depmod -ae worked great. It fixed the cd-rom and the floppy problem. Thanks alot Linuxcool. Sorry I did not tried that before but I dont like to run commands I dont know about.
Again thanks alot Linuxcool you just allowed me to consider Linux as a good think again. Because in the beginning, I was really optimistic about this great software but lately I was starting to be a little (a lot ) frustrated and was thinking of throwing it at the ends of my arms!!
P.S. Could someone clarify for me what the depmod -ae command does.
Thanks again to all the great people who took time to help me.
I really appreciate it!!
Now I can get on with the test I want to conduct. Testing the network capacity of Linux!!!!
I don't understand depmod much myself. According to the man page for it, the ' a ' option causes it to create a file that is used by ' modprobe ' to load the correct modules. Maybe someone else can do a much better job of explaining it.
Red Hat said something about it being a problem in their installer that was the cause for the ' not a valid block device ' error and it would be fixed in the next release.
Also, if you reinstall, you will have to run depmod -ae again.
