- Well for me sometimes it will run a 320x200 in a window, but for some reason
- on other programs it will say "video mode cannot be run in a window -- program
- suspended..." or some such.

- Yes the colors get screwed up. Yes the drivers are kind of slow.
- Remember, these are *beta* drivers. I find the 1024x268 to be serviceable,
- but it frequently crashes and is slow. I'm just hoping the IBM produced CSD
- ET-4000 drivers will be better.

-
- Hmmm. This doesn't sound right. The 1024x16 driver I tried was definitely
- different and *faster*.
-
- Now some oddities I've discovered with Orchid's 1024x256 driver:
-
- I recently upgraded my Motherboard + video from a 386-40 with a IIs to a
- 486-33 Local Bus ET-4000. After some fiddling I got it running fine. But,
- a day or so later I noticed that after C-ESC'ing, and then returning to a
- full-screen program my screen was blank and it looked like my monitor was no
- longer recieving a signal from the computer (I have a Nanao which beeps when
- the CPU is turned off and it was making this beeping noise after trying to
- resume the session). I tried doing this with several other programs and
- it was the same for all.
-
- Just by plain, dumb luck I tested the above with just a plain dos command
- shell window (ALT-HOME to make it fullscreen, then CTRL-ESC, then return to
- full screen) and that worked. After that it worked for *everything*!
- Now, this *sounded* very familiar to a thread a while back. Can anyone
- confirm that this has happened to them, or know what causes it, or know
- of a better solution than enlarging a DOS window to get this to work right?
-
- Also FYI: although the readme for the drivers say the max supported at 1024x256
- is 60Mhz, I configured my card/monitor for 70Mhz, ran svga on, rebooted,
- and the driver works fine (well, at least as good as it did, but less flicker).
