- Hmmm... My Diamond Speedstar (non-HiColor) definitely fits the "problematic"
- description. The Orchid drivers (proii4 & proii8) work ok on my Gateway
- 2000 386sx though the 256 color drivers are little slow and the colors are
- off. I've been using the 1024x768x16 driver. WPS and OS/2 full screen,
- OS/2 window, and DOS window worked fine. DOS full screen and WINOS2 full
- screen are not so great. I switched to the generic et4000 drivers and am
- using the 1024x768, 60Hz driver which I patched using BEAV for smaller
- icons. The results appear nearly identical to the 1024x768x16 Orchid
- driver.
-
- An alt-home from a DOS window brings me to a full screen of total hash.
- Another alt-home restores me to the WPS desktop in good order. After
- starting a full screen session (DOS or OS/2), this improves from garbage
- to... wierd.
-
- When I start a full screen DOS session, it looks fine. If I alt-home or
- alt-esc, I end up back at the desktop appropriately, but when I alt-home
- the window back to full screen or select a full screen DOS session I
- switched away from, the display is distorted. It's like the horizontal
- sync timing is off a bit -- the beam coms back on a moment before it's
- been restored to the left margin. That's with a 25 line display. With
- a 50 line display, I have two flickery copies of the screen combined
- with the horizontal sync timing still lookiing a bit off. I can clear
- these problems up temporarily by entering the appropriate mode commands,
- but the next time I switch away and come back, the problem will be back.
-
- I haven't tried to change the display driver for WINOS2 yet, so it's still
- at 640x480x16 and as with DOS, it look fine when initially started, but
- switch to the WPS desktop and back again and it looks... wierd. the
- display is "squished" vertically.
-
- As I've read this thread today, I noticed that some people have run
- VMODE in a DOS session. In order to get 1024x768x60Hz non-interlaced
- in DOS, I have to run VMODE, but I haven't done that in a VDM. Maybe
- I need to do that and rerun SVGA ON. What do you think? I think I'm
- going to try it this weekend. Is there anything else I should try?
-
- BTW: I have the the fx3 version of the VSVGA.DLL fix installed. I
- also have the patch BVHSVGA.DLL (I think I spelled that right) as well
- as a number of other non-video patches thanks to ftp-os2.nmsu.edu. I'm
- happy to say that I havn't experienced any trap 2's, 5's, or E's lately.
-
- Regarding seemless Windows: as I understand it, there are no drivers
- available for me to to this with my Speedstar in SVGA mode, at present.
- Also, I'm still running the generic et4000 drivers and cannot run WINOS2
- in a desktop window -- I should be able to do this, right? Though not
- necessarily with these converted 1.3 drivers (right?). They have to be
- real 2.0 drivers to do that (right?).
-
- In previous et4000 threads, I've read that IBM's CSD will include et4000
- drivers. I hope that they will have 1024x768x16 & 1024x768x256 versions
- (I know! I know! I'm crazy run 1024x768 on a 14'' monitor, but I'm near-
- sighted and don't seem to have trouble reading it. Still, I've seen some
- larger monitors at 1024x768 and I agree that it's better. I would like
- to get one - $$$$$$!).
