This is because the boot image on the NetBSD cd is a 2.88MB image, but
the Thinkpad BIOS only supports 1.44MB boot images. This has been
reported to IBM, but they've never done anything about it.

Some time ago someone suggested that the NetBSD boot image should be
split into two 1.44MB images or something, but I again I don't think
anything was ever done. I think you can find the relevant threads if
you search back through port-i386 (and possibly netbsd-current)
archives searching for Thinkpad and 2.88.

The two solutions I've used are:

1) Create NetBSD boot floppies, boot from them, then mount the CD and
   run the install.

2) remove the hard disk from your Thinkpad, buy a 2.5 - 3.5 adapter
   (about $10 + shipping at buy.com), plug it into a desktop and
   install, then plug it back into the laptop.
