Hi,

i've read the FAQ and googled for it, but did not find
any answer.

The problem:

I have a working linux installed on a 20 G hard disk.
I boots up with "grub", everything works fine, except
that disk space is too small.

I just bought an 80 G hard disk and want to copy the
system over to that disk "as it is".

So i booted my system with /dev/hda as the 20 G disk
and have the other disk (80 G) available as /dev/hdb.
I partitioned, formatted /dev/hdb and copied the the
normal files, no problem.

Now i'd like to also make the disk bootable via grub.


Some years ago when i used lilo (an other boot loader)
there was the possibility to install it it on a hard disk
/dev/hdb so that it would boot up fine when it would be
attached as /dev/hda in a PC.  If i remember the parameter
necessary was bios=0x81 or something like that.


Is it possible for grub to install on a disk /dev/hdb,
then switch off the PC, remove disk /dev/hda and replace
it with the former disk /dev/hdb that would then boot up
as /dev/hda?

I hope it is clear what i want to do, is something like this
possible?


Thanks for any hints,
Torsten.
