Hi Michael I have read your problem with your CDrom drive on the SuSE list. I have a similiar setup to you, Acer 24x CDrom, 3.4gb and 1.2gb hard disks and was wondering if you can help? I attempted to install SuSE 6.0 using the standard 2.0.36 kernel and I kept on getting this error message after Linux had booted for the first time and went to finalise settings with YaST: An error occured mounting the CD. The error output of the mount command is: mount: wrong fs type, bad option, bad superblock on /dev/hdd or too many mounted file systems I have now managed to install SuSE 6 but I still have problems: I notice that I can only mount the SuSE CDs with the drive spinning, should the drive spin down (after 5mins) then I can not mount the CD (lights flash etc and irq timeout errors appear in the /var/log/messages see below). Interestingly this seems to only happen with the SuSE CDs, all 5 of them! A copy of RedHat 5.2 can be accessed all the time, even after CDrom spin down. All CDs can be read in Win98. Any ideas?

Ok, I patched to 2.2.5, ran setup and took out SCSI emulation and added the CMD640 chipset fix support, added the BSD process accounting support, applied the patch to fix the errors with it, recompiled, ran lilo, rebooted, ran BIOS setup, set the secondary master to none, rebooted, and here's what I got:

Thanks for the tip on the BIOS setting Craig.

It's possible that some changes either in mount or modutils might be causing some confusion somewhere.

Here is how the drives are set up:

Primary Master: Quantum 4.3 GB UDMA Primary Slave: Fujitsu 1.2 GB EIDE Secondary Master: Acer 24x ATAPI CD-ROM Secondary Slave: -None-

BIOS recognizes them all fine. I'm not sure I understand how setting the system with NO CD-ROM will help Linux pick it up?

I am sure I _don't_ understand it; all I know is on my machine it does. The BIOS boot messages (HX/Award) read out the primary master, primary slave, and secondary master, then "None", then the "None" is replaced by the CD identification string about a second later. What chipset and BIOS do you have?

BTW, I've ruled out any problem with mount, so it has to be either kernel or hardware related. I tried booting from the CD-ROM drive, and that works fine, so I'm assuming that rules out hardware, leaving a kernel problem. I've checked every option seemingly half a million times in the kernel setup, and compiled about six times now, with no luck...

In addition, mount now results in: mount: the kernel does not recognize /dev/hdc as a block device (maybe `insmod driver'?) That seems to me to indicate that a module for the driver is not

loaded,

but I didn't compile anything in the kernel as a module...

I installed SuSE 6.0 a couple of weeks ago, and have been using the 2.0.36 bundled kernel. I finally got some time this weekend and compiled/installed the 2.2.4 kernel. However, now my CD-ROM
