Linux installation problem

Linux installation problem

[mshiju]

Hi all,
           I am trying to install Linux (redhat-7) on a ps/2 server-9595
machine (mca ). I am booting from a floppy disk and using a custom build
2.4.1 kernel image since there are problems  booting  the machine using the
installation image on  redhat CD and also it is not CD bootable. The
problem is that after booting it asks for redhat CDROM and when I insert
the redhat CDROM it gives a message "I could not find a redhat linux CDROM
in any of your CDROM drives ". The CD drive is a SCSI device and I have
enabled SCSI cdrom in kernel compilation . Can any one help me .

Thanks & Regards
Shiju

Hi,

I have a type 8560 PS/2... not the same as yours but I did install slackware
on
it once.

I would suggest installing from a standard PC.  Boot disks are very
inflexible,
since you don't have any utilities to poke around and figure out what's going
on.

Once you have a complete root filesystem, once you've got a kernel to
recognise your scsi adapter, (and disk), you're off to the races, and can
use all kinds of tools to look into the CDROM problem...BUT

it's probably not going to recognise the disk either...

check different virtual consoles with alt-f1, f2, etc: under
a normal redhat boot disk, the different vc's will have diagnostic
messages, ie kernel messages, list of modules being loaded, etc.

maybe the best way is to be sure to compile kernel with support
for scsi subsystem *in kernel* - not module, along with
scsi-disk, scsi-cdrom, and your scsi host adapter.  the last
one may be the tricky one.  you will have to figure out if it is supported.
(the one in my PS/2 is at least for 2.0 kernel)

if you can make the kernel on the boot disk use a smaller font,
you will be able to see more of the messages at once.

also, shift-PgUp should let you scroll back some of the messages.
look for the kernel messages from your scsi host adapter driver...
if you don't see any there's a problem!

take a look inside your box and see what kind of scsi adapter it has.
or use your reference disk to see what it is.  post that here
so someone (maybe me) can check for kernel support.

Cheers,

Jeremy

8560? Isn't that a 286?! Is it processor-upgraded?

The 8595 either has an IBM FAST SCSI/2 (uses ibmmca) or an FD
MCS-600/700 (uses fd_mcs).

I've never ever installed any of my MCA-machines from CD, only using the
a couple of boot-disks and installing the rest via net.

Oh, and for that matter, I've never installed Red Hat either, but that
shouldn't matter.

Standard Red Hat has no MCA support (sorry much as I love my PS/2 its rather
hard to make an honest business case for the huge amount of extra work to
build MCA boot disks/CD images).  Debian I believe should install straight out
of the box on most MCA bus PC systems

 CDROM is detected. On booting it gives the following messages
######################

Detected scsi CD-ROM sr0 at scsi0, channel 0, id 12, lun 0
sr0: scsi-1 drive
Uniform CD-ROM driver Revision: 3.12

#############################

The kernel message from the  virtual consol is as follows:

########################
trying to mount device scd0
loopfd is -1
LOP_SET_FD failed : Bad file descriptor

####################

Where am I gone wrong?

Thanks & Regards
