hmm, no errors there. here's the contents:
# partition table of /dev/hde
unit: sectors
/dev/hde1 : start= 63, size= 3871602, Id=83, bootable
/dev/hde2 : start= 3871665, size= 240975, Id= 5
/dev/hde3 : start= 0, size= 0, Id= 0
/dev/hde4 : start= 0, size= 0, Id= 0
/dev/hde5 : start= 3871728, size= 240912, Id=82

You say this later, but somthing that's bothered me about this is that
I don't see how to instlal grub on /dev/hde and then point it to the
proper menu.lst. (right now, on my main workstation, / is on
/dev/hda2. on these disks I'm formatting, / should be on the first
partition. How do I tell grub-install to look on /dev/hda2 for the
root filesystem & the menu.lst file?) This is probably a trivial
problem, but I guess I don't understand the docs very well.
anyway, thanks, I guess if someone can clarify the GRUB thing to me I
wil ltry it that way!
