I only use --enable-diskonchip-2000. No netboot.

I changed it to ext2. No avail. It just won't find anything on that
disk; all it says is "unknown filesystem type 0x83" when i set 
"root (hd0,0)", so I assume grub can read my partition table. Which
looks like this:

Disk /dev/hdc: 524 cylinders, 64 heads, 63 sectors/track
Units = sectors of 512 bytes, counting from 0

   Device Boot    Start       End  #sectors  Id  System
/dev/hdc1   *        63   2032127   2032065  83  Linux
/dev/hdc2       2032128   2112767     80640  82  Linux swap


Anyway. I was looking for those blocks:

debugfs:  stat vmlinuz-2.4.18

BLOCKS:
(0-11):66038-66049, (IND):66050, (12-278):66051-66317
TOTAL: 280

But that doesn't seem to work either. 

"kernel (hd0,0)66038+280" does just nothing, namely
"Invalid or unsupported executable format" -- you always get that
when referencing to some bogus structure on the disk. Does grub
use other blocks than those? 

slowly I'm beginning to think I should subscribe to some 
grub-mailinglist. 

thank you anyway.
