Since Toshiba still has not gotten any OS/2 drivers out for the T4600C notebook,
I thought I would mention a couple of things I've learned about the combination:
1. The Advanced Power Management Works! Without much special tweaking.
I suggest getting "TSETUP.EXE", a DOS system setup utility, and "MAXTIME.*"
the two Windows files associated with Maxtime, the Windows system utility
and copy them to a directory. Then create icons to launch them. As far as I can
tell it works great -- including the ability to enter an estimated battery setting
when the LCD has no display for time remaining.
2. I discovered, to my amazement, that the Auto-resume feature also works
perfectly with OS/2. No need to reboot every time you shut down. Just turn the
power off and next time you turn it on, you are immediately right where you were
when you left off. You turn RESUME mode on in MAXTIME. (One note: using another
manufacturers PCMCIA modem, the modem shuts down when you turn off the
T4600 and does not wake up when you turn it back on. You have to do a warm
reboot.)
3. I had a lot of trouble with Video. The T4600C uses a Western Digital Chip
set. OS/2 thinks it supports it, but it is not one of the WD chips that really
is supported. (The chip set is WD90626A, I am told.) The result was that I could
not get seamless WinOS/2 sessions to run. When I tried to reinstall video
support I got a lot of weird combinations, none of which was right. I got SVGA
modes that corrupted the desktop display and others that tried to run VESA
TSR's in DOS and Windows sessions. Once I got seamless Windows to run for
a day. the next day, it was broken again. And I had done nothing to any settings!
IBM gave me the following tip to reinstall VGA (the only mode supported until
TOSHIBA gets moving and gives us some drivers):
Open an OS/2 window or full screen session and log onto the \OS2\INSTALL
directory. Then type the following command:
RSPDSPI /PK:VGA /SK:NONE /S:A:\ /T:C:
I have no idea what any of this means, so be warned! Then you put the
requested installation disk (Display Disk1) in drive A: and... supported VGA
reinstalls perfectly. Seamless Windows in 16 glorious colors! TOSHIBA, please
give us SVGA drivers!
4. Don't buy the SCSI adapter TOSHIBA makes for the bus connector. Even
though it is supposed to be Adaptec compatible, it does not seem to work under
OS/2 -- and I really did not expect it to when I read the manual. But TOSHIBA
tech support had told me that they thought it was supported by the Adaptec
driver, so I bought it. Now I'm stuck with a useless piece of hardware. Please,
TOSHIBA, an OS/2 driver for the SCSI adapter!
5. I was told by TOSHIBA that their PCMCIA card does not support OS/2.
I bought the Chapelet card as a beta tester to see if it works under OS/2. The
answer so far: no. So I bought the IBM 14.4/14.4 PCMCIA fax modem. It works
fine as COM2. An installation disk comes with it. I told it I had a T4400 or T4500
or whatever and it worked. I don't think it even involved installing any drivers
that aren't part of OS/2. (The only downside, I have to do a warm boot to
wake the modem up after going into suspend-resume mode.)
Anyway, I recommend OS/2 2.1 on the T4600C with 20 Meg or RAM. It works
like a dream.
