I think this presumes that the HD is examined at boot time, instead of stopping once the system sees a bootable CDROM, which is the normal case when doing a recovery. You should talk to Evan Oldford (evan@whistle.com, eoldford@us.ibm.com) about his experiences recovering with the recovery CDROM, after having trashed several models of thinkpads with FreeBSD installs gone wrong. Obviously, you could also recover by removing the hard drive and zapping it, but the technical note referred to by the original author of this subject specifically states that there are utilities that can recover the HDD to a bootable state: "The HDD can be recovered to make the system bootable again using various utilities. However, IBM does not recommend any specific utility or support the use of any of these utilities." I think the "magic" combo to force it to ignore the HDD is something like "Alt-F6" during boot, but don't quote me: it's printed in the ThinkPad manual that comes with each ThinkPad.
