ThinkPad 720 PCMCIA Drivers Diskette Version 1.12
1. TP 720 PCMCIA Drivers Diskette History:
Version 1.00 - Release Level
Version 1.10 - Fixes problems associated with the Power On Process
of some PCMCIA I/O Cards, such as machine re-booting
when some cards power on.
Version 1.11 - Fixes Trap D error on OS/2.
- Only $ICPMOS2.SYS is updated.
- This version not implemented in US. Instead, the diskette
version skips from 1.10 to 1.12.
Version 1.12 - Fixes problem reading some cards CIS data due to
access speed mismatch. For example, enables 720 to
read Megahertz Modem CIS data through DOS Card
Services so a Client Driver provided by Megahertz
in the future should work with the TP720's DOS Card
Services. (Currently, Megahertz modems are using
point enablers and do not use Card Services, so this problem
has not yet been seen in actual applications).
- Includes Version 1.11 changes.
- IBMDOSCS.SYS is updated.
- As of 11 AUG 93, this version is only available in
the US.
