Thanks for your suggestions. Here's where things |
44 |
stand: |
45 |
|
46 |
I did a fresh 2005.1 stage3 install onto the SATA |
47 |
drive without a hitch. I removed the ide drive, so |
48 |
there's only one hd. |
49 |
|
50 |
In dmesg the drive comes up as /dev/sda |
51 |
sda1(Macro$haft) sda2(/boot) < sda5(swap) sda6(/) |
52 |
sda7(home)> |
53 |
|
54 |
When I boot w/ the grub floppy I do: |
55 |
|
56 |
grub> root (hd0,1) |
57 |
Fs is ext2, part type 0x83 |
58 |
grub> kernel /vmlinuz root=/dev/sda6 |
59 |
[Linux-bzImage, setup=0x120, size 0x1463b31] |
60 |
|
61 |
...so far, so good... |
62 |
|
63 |
grub> boot |
64 |
|
65 |
and get: |
66 |
|
67 |
...VFS: Cannot open root device "sda6" or unknown |
68 |
block (0,0) |
69 |
Please append correct "root" boot option |
70 |
Kernel Panic-not syncing: VFS: Unable to mount root fs |
71 |
on unknown block (0,0) |
72 |
|
73 |
So I'm at a loss. The grub commands went alright. |
74 |
Wouldn't I get an error if one of the commands was |
75 |
wrong? Don't know what's meant by "unknown block |
76 |
(0,0)". Is it saying it's trying to mount / on |
77 |
/dev/sda1? Doesn't make sense. |
78 |
|
79 |
WinXP occupies 20G at /dev/sda1 and it boots OK. LBA |
80 |
is activated and this is a brand new, modern drive on |
81 |
a fairly up-to-date Asus, K8N, skt 754 mobo, so it |
82 |
can't be that old BIOS drive limit from the 90s. |
