No it isn't a ThinkPad, it's a Bullman (noname), similar to an Acer.

FreeBSD runs without change to the bootblock.
NetBSD 3.1 runs as well, but during install I have to specify the disk 
geometry.

This night I installed DragonFly 1.4.0-RELEASE (via dfly.iso) on it, and 
it works perfectly!

Strange is that NetBSD seems to use a different disk geometry than 
DragonFly 1.4, and DragonFly 1.8 uses a different one as well!


> uname
DragonFly 1.4.0-RELEASE

> fdisk
in-core disklabel geometry
cylinders=20672 heads=45 sectors/track=63
  (2835 blks/cyl)

BIOS geometry: same as above

sysid 165
  start 63, size 58605057 (28615 MB)
  beg: cyl 0 head 1 sector 1
  end: cyl 191 head 44 sector 63


Strange, when I boot the DragonFly 1.8.0-RELEASE installer (after 
installation of 1.4 or modifying the harddisk) I get:

> uname
DragonFly 1.8.0-RELEASE

> fdisk
cylinders=58140 heads=16 sectors/track=63 (1008 blks/cyl)


I don't know about the issues involved with different disk geometries, 
but as this is the only difference I see between DragonFly 1.4 and 1.8, 
maybe this might be a problem?
