Hallo xenusers!
I want port a very old sco to to xenU.
Under xen cannot boot this image.
This Partition cannot mounted.
Whats going wrong?
Is HD-geometry a cause of this problem?

You must set cylinders.
You can do this from the extra functions menu.
Disk sco.dd: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

# or: lomount -diskimage $hdimg -partition 4 $mntdir
df $mntdirdst
umount $mntdirdst
losetup -d $devloop
-------------
- result:
# lsmod | grep sysv
sysv 28804 0
# lomount -diskimage $hdimg -partition 4 $mntdir
mount: you must specify the filesystem type
# mount -t sysv $devloop $mntdir
mount: wrong fs type, bad option, bad superblock on /dev/loop1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
