Grub news

Some small encouraging news with cromwell.  

It is now able to boot up grub fully, but then after a couple of seconds' disc 
activity it falls silent.

I know that grub is starting (involving many sectors being pulled from the HDD 
okay) because I overrode int 10h and made it dump to a RAM buffer which I can 
inspect on the next reboot

wait.......

Here is the contents of /boot/grub/menu.lst

hiddenmenu
timeout 1
default 0

title linux
kernel (hd0,1)/boot/vmlinuz root=/dev/hda2 devfs=mount kbd-reset
initrd (hd0,1)/boot/initrd

As I understand it the hiddenmenu should just remove all of the grub user 
interface.  I had a look at 0xb8000 and 0xa0000 to see if there was any text 
or graphics placed there and there isn't.

It seems to me that either grub is stalling, perhaps waiting for input that 
never comes, perhaps trying to init a nonexistant VGA BIOS, or that Linux is 
starting and oopsing right away.  Much as I would love to believe the latter 
there is nothing in /var/log/messages to suggest its true.

Any ideas welcome, as usual!
