Hi,
As I tried many unseccessful combinations of LILO and NTLDR+BOOTPART to
multiboot various versions of Linux/WindowsNT, I discovered GRUB which
appeared to be the _solution_.
My disks configuration (output of fdisk -l /dev/xxx):

As it can be seen, my SCSI disk is perfectly detected under GRUB shell.

As a step toward total migration to GRUB, I decided to firstly install
GRUB on floppy disk. After many newbie errors, I ended up using the
attached script found on an Mandrake distribution (slightly modified),
with attached output and using attached configuration file.
Results are as expected for booting WindowsNT from (hd0) and Linux from
(hd1,0), (hd2,0) but (hd3,5) fails saying like "the disk doesnt exist".
By entering the shell and entering "root (hd<TAB>", it displays only
(hd0) (hd1) (hd2). Entering "root (hd3,<TAB>" also fails of course.
Sorry for the verbosity - I hope I'm in accordance with the "Reporting
bugs" section of docs I just read.
I compiled GRUB checkout from cvs.
Regards
