Very Computer

Pentium P75, PCI, 2HDDs (One for W95, one for Linux), CD-ROM,
SMC Ultra ethernet card.

The CD-ROM is an Aztech 46802I, cabled directly to the 2nd IDE socket
on the motherboard, and jumpered to be the master device on that socket.

Using the idecd boot disk, I can boot the system and (usually) recognise
the CD-ROM drive. At boot time there are messages like this:

hda: (correct details of first HDD)
hdb: (correct details of second HDD)
hdc: IRQ probe failed (0)
hdc: CDA46802I, ATAPI, CDROM drive
ide1: secondary interface on irq 15
ide0: primary interface on irq 14

...and I can install a fully working, bootable system without difficulty.

BUT, when I build myself a new kernel, using the IDE CD option and the
primary/secondary IDE option as described in the ATAPI FAQ, the CD-ROM
drive is not recognised. Instead of the messages as above, I get:

hda: (correct details of first HDD)
hdb: (correct details of second HDD)
hdc: no response (status=0x90)
ide0: primary interface on irq 14

Can anyone shed any light on this?

Thanks

Richard

If you use the same kernal for the Aztech as the Wearnes CDD-110, you are
shit out of luck. I don't care what anyonme says, but the Wearnes CDD-110
is just not supported at all. Any attempt to use the azt kernal results
in a lame error and fake apology. You'll need to get a new CD drive if
you want to punish yourself with Linux.

By replacing idecd boot by abare boot and CDA46802I by CDA668-01I (a CDROMx6
IDE/ATAPI), I have almost
exactly the same problem. With boot and root disks (with ramdisk hdd=cdrom
as boot parameter), my cdrom is viewable. AFTER a reboot, with the
kernel abare 1.3.18, my cdrom disapear ! I think, I have to write something
like hdd = cdrom in the lilo.conf file, but WHAT IS THE SYNTAX ?
append = "hdd = cdrom" does not work. Thanks in advanve. pg.

LILO: linux hdc=cdrom

And it seems this option can be specified as part of the LILO
configuration to avoid having to enter it at every boot.

Thanks!
