Thanks for your suggestions. Here's where things
stand:
I did a fresh 2005.1 stage3 install onto the SATA
drive without a hitch. I removed the ide drive, so
there's only one hd.
In dmesg the drive comes up as /dev/sda
sda1(Macro$haft) sda2(/boot) < sda5(swap) sda6(/)
sda7(home)>
When I boot w/ the grub floppy I do:
grub> root (hd0,1)
Fs is ext2, part type 0x83
grub> kernel /vmlinuz root=/dev/sda6
[Linux-bzImage, setup=0x120, size 0x1463b31]
...so far, so good...
grub> boot
and get:
...VFS: Cannot open root device "sda6" or unknown
block (0,0)
Please append correct "root" boot option
Kernel Panic-not syncing: VFS: Unable to mount root fs
on unknown block (0,0)
So I'm at a loss. The grub commands went alright.
Wouldn't I get an error if one of the commands was
wrong? Don't know what's meant by "unknown block
(0,0)". Is it saying it's trying to mount / on
/dev/sda1? Doesn't make sense.
WinXP occupies 20G at /dev/sda1 and it boots OK. LBA
is activated and this is a brand new, modern drive on
a fairly up-to-date Asus, K8N, skt 754 mobo, so it
can't be that old BIOS drive limit from the 90s.
