IBM ThinkPad A22e
Mark: Very good
I have an A22e, which is almost identical to a T21 (I think the T21
case is a little stronger). Suspend, and hibernation, work fine. To
make it work, I did the following:
- I shrunk the C: drive (Win98, in my case), using DFSEE (I made it
5GiB, just because...).
- Then, I used LVM to add Boot Manager, immediately following the C:
drive. If you find the right docs, you will find that the save file
must be on a FAT, FAT32, or NTFS, formatted drive, that is FIRST on
the disk (mine is FAT32). There is no need for a "special partition"
to do suspend, or hibernate, except on older computers, that don't
have the BIOS support to do it. Putting Boot Manager first on the disk
will mess that up. Boot Manager could also be put at the end of the
disk (as long as the Int13X support will go that far out, and it
should). Since my disk has the recovery partition (hidden), at the end
of the disk, I just left it there, and built my eCS system volumes in
the middle (all extended, logical, of course). I have a 2047 MiB boot
volume, and a 20 GiB (or so) JFS volume.
Then, I set up the BIOS to do the suspend, and hibernate, functions.
ECS cooperates with that, and it works fine. I did select the option
that will rebuild the save file, every time it is created.
Some problems that I did have, before I got it to work:
- The driver for the NIC (Intel Pro 10/100 combo card) did not support
suspend and resume. A later version of the driver works fine (included
in eCS 1.2, and up, and it may even be in eCS 1.1). Get NICPAK from:
if you aren't sure. That page will also get you the proper download,
if you need to update.
- There was (is?) a bug in the Speedstep driver, that prevents the
screen from being refreshed after a resume. The latest Speedstep
driver is supposed to have a fix for that (there is an entry required
in CONFIG.SYS to enable it), but I find that it will work twice, then
it never works again, until you reboot. The actual fix for that
problem, is to add: SET SNAP_APM_REPAINT=1 to CONFIG.SYS.
The SNAP driver will do a repaint, a few seconds after
resume is completed.
- One thing that does NOT work, on my system, is the Lucent modem. It
happens to be one of the many unsupported versions. You will find that
getting one of the Lucent modems that does work, is a hit and miss
thing. Some T models have a good one, and some don't. Same goes for
the rest of the Thinkpad models. Some have the good modem, and some
don't. IBM will NOT replace a modem just because it doesn't work with
OS/2, and there is no guarantee of which type you will get, if you
need to replace a working (or not working) one.
