Try pressing the key that brings up the boot device menu (F12 on my

I've often found it won't ever boot from CD if there is a valid MBR
on the HD without using the menu (that makes it boot faster...)
I tried that, *and* disabling the hard drive boot sector (which you can do on a Thinkpad thru the BIOS). I believe it may be an issue with the drive being too old to recognize a multisession boot CD, so I'm going to try booting from a pure cd40.iso image first, and then inserting the original CD (that won't boot) during package install.
