I've just installed RH 7.3 on a machine with all-SCSI discs. I had to load "linux dd" with Adaptec AIC 79xx driver floppy installed, but that's ok.
The / is mounted from /dev/sdb1.

So, I got a clean 2.4.20 kernel, added AIC 79xx driver sources to the kernel source tree, configured and compiled and installed it (of course, I didn't forget about the modules).

In lilo, I said "root=/dev/sdb1" just as for the original 2.4.18-3 RedHatkernel which boots ok.

When I boot the new kernel, I get:
VFS: Cannot open root device at "811" or "08:11"

From SCSI-howto I got that 08:11 stands for /dev/sda11. Why would /dev/sdb1 be converted to 08:11 instead of 08:17 (again, corresponding to SCSI-howto)?

Those number are in hex, so "811" is major 8, minor 17 which is (or should be) /dev/sdb1. Look earlier in the boot up sequence, where the aic79xx driver is loaded and scans for devices. It should say that it has attached /dev/sdb . You may need a later version of that driver. Visit:

Thank you very much!

I found the source tarball there - aic79xx-linux-2.4-20030520-tar.gz.

(Also, what is aic79xx-linux-2.4-20030520.bksend.gz - seems to be some changelog?)

I will to build everything today (I have two AIC 7902 drives on that machine).

Many thanks again.

Artemio.
