I have 2 Hard discs. hd0 is IDE. hd1 is SCSI The SCSI controller is a very old Adaptec AHA-2940.
After booting from a floppy containing grub: -
grub> geometry (hd0) Displays geometry and returns to grub> prompt. grub> geometry (hd1) Displays geometry and causes an immeadiate reboot!
It is only the SCSI drive that has problems.
hd1 has only one primary partition, containing a FAT32 formatted partition with Windows 98 on it.
From looking at the grub source code, it looks like: - File is stage2/builtins.c
/* geometry */
static int
geometry_func (char *arg, int flags)
{<snip>
grub_printf ("drive 0x%x: C/H/S = %d/%d/%d, "
"The number of sectors = %d, %s\n",
current_drive,
geom.cylinders, geom.heads, geom.sectors,
geom.total_sectors, msg);
real_open_partition (1);
return 0; }
So, as it gets and actually prints that information from the grub_printf, my guess is the problem is in real_open_partition(1).
What exactly does real_open_partition(1) do, and can I remove that line for test purposes?
If by removing it, the geometry command works, I can then look at the real_open_partition function, and add a few grub_printf's to see where it reboots.
Does grub have a "grub_pause_for_1_second" function? That would also help by giving me a chance to see what is printed before the reboot.
Cheers James
