I'm using the XLT MILO and finally can report success:
the problem with MILO unable to spin up the disk was solved by
setting a jumper on the hard drive (PARITY DISABLE). So booting
using MILO works mostly, except that it doesn't do it automatically.
E.G. I can boot the installed Debian/Linux on the harddrive with:
MILO> boot scda1:/boot/vmlinuz root=/dev/sda1
I also figured out that there is a boot image on the CD at sr0:boot/linux,
however I didn't figure out what the exact command line is for booting
the debian installer from CDROM. At least something like
'boot sr0:boot/linux root=/dev/scd0 load_ramdisk=1' doesn't work,
since no ramdisk is found, and I don't find any that I could
specify on the command line with 'initrd='.

I can now run X from the XLT MILO, 3d works aswell (if I use 16bpp,
Voodoos hardware limitation).
However I have to boot from CDROM, start the XLT MILO, enter the boot
command until I finally can use my machine.
So now I try to create a FAT partition, put MILO on it so I can use
my Linux on the harddisk (which was installed using SRM, but luckily
MILO understands BSD disklabels).
Thanks, Max
