I've been struggling for several weeks to get my thinkpad up and
running some flavor of UNIX. So far I've tried linux, freebsd,
and netbsd, with no success. What I'm finding is that this machine
is very incompatible with other [34]86 boxes, so the various
UNIX-like operating systems won't talk to it.

+ the (2.88 mb) floppy controller is different. linux can't read
  from its floppy disk in order to install the rest of the system.

+ the hard disk drive geometry is not in the eeprom, so systems
  that look there for the geometry will fail.

+ When I do get the linux system booted at all, it comes up with
  the keyboard as if the 'Fn' key were pressed. So when I try to
  log in as 'root' it looks like 'r66t'.

+ I have a Dock 1. I've tried plugging in an AT hard/floppy controller
  with a 1.44 Mb floppy attached (to get around the floppy drive problem).
  No matter what jumper settings, (either the primary or secondary
  controller addresses) the system will not boot with this installed.

+ I've also tried plugging in an external keyboard to the Dock 1's
  keyboard jack. That didn't work either...it's just ignored.
  (Naturally I don't have the "keyboard/mouse connector option"...so
  I can't connect it to the thinkpad's mouse jack.)

+ Either Linux doesn't recognize the scsi controller in the Dock 1,
  or it doesn't recognize the CDROM drive. What kind of SCSI controller
  is this? Is it compatible with anybody else?

+ I suppose getting the pcmcia ether card to work is out of the question?

+ The external scsi connector on the Dock 1 is a 60(!) pin connector
  of a type I've never seen before. Where can I get an adapter from
  this to something that's more standard? (or just a ribbon cable
  connector!)

All in all, I'm very frustrated with this machine. Can anyone help
me get this thing going or answer any of these questions?

Thanks very much,

Keith Moore
