Hello,
Since you did not explicitly mention it, did you mark a
partition on the CompactFlash device as "active" or "startable?"
IBM did manufacture one laptop designed to boot from a variety
of devices, the IBM Palmtop PC110. About the size of a large
paperback book, it contained a 486SX processor, tiny keyboard,
pointing device, passive screen, and two PCMCIA slots which would
accept a PCMCIA hard drive. It also had a PicoFlash (predecessor
to CompactFlash) slot which would take a Type-I solid-state CF card
(IBM's own Microdrives draw too much amperage, if I recall, to be
used in an unmodified PC110). They were sold in Japan during the
mid-90s and occasionally one pops up on eBay.
Booting from the PicoFlash slot is a subject which frequently
comes up on the IBM PalmTop PC110 mailing list. It appears that
some CompactFlash cards work (Lexar, SanDisk, Simple), while others
do not (Memorex).
Assuming that the ThinkPad 701C functions in a similar fashion you
may need to try a different brand of CF card before you find one
that works.
You mentioned that you snipped a pin, presumedly on the CompactFlash
adapter. If you reconnect this pin, does the CF card behave differently?
Regards,
Aryeh Goretsky
