Can't open root device error -- PCP210 and YDL3

[Christopher Vargas]

Trying to get a few more miles out of my old PowerCenter Pro 210 (with 
XLR8 400 MHz G3 upgrade card) by installing YDL3 on it. It seems I'm 
almost there but just can't get it to boot after installation. Hoping 
someone can help.

I'm following the directions to the letter (I think), with the 
exception of not being able to use Drive Setup, since my big 4GB 
Western Digital drive is not recognized as being an Apple drive (and as 
far as I can tell, I can't use the ResEdit hack on Drive Setup for this 
drive). I used SilverLining instead, made a 1GB partition for MacOS 9, 
and left 3GB unallocated for the YDL installer to use.

Did all the BootX setup as described, rebooted with YDL3 disc 1, let 
the installer partition things on its own. It makes a swap and root 
partition, with root at /dev/sda5 and swap at /dev/sda7 (the Mac OS 9 
partition is /dev/sda6). Installation proceeds normally.

When I reboot I set BootX to the appropriate kernel and turn off RAM 
disk, and set boot to /dev/sda5. I click Linux, a bunch of CLI stuff 
scrolls across the screen and then I get the following:

VFS: Cannot open root device "sda5" or 08:05
Please append a correct "root=" boot option
Kernal panic: VFS: Unable to mount root fs on 08:05
Rebooting in 180 seconds

I'm at a loss for what to do now. Any help would be appreciated. I'm 
subscribed to the digest so if possible, email me directly at 
cv@chrisandmaria.com as well as to the list. Thanks very much.
