[ Article crossposted from comp.os.os2.apps ] [ Author was ] [ Posted on 10 May 1994 03:33:22 GMT ] Hi all, I've got a CAD machine that I've recently installed OS/2 on & I'm trying to source some drivers that will allow OS/2 to fully utilise the graphics card that it has. The machine involved is a DECpc 433T with an Intelligent graphics card (dec p/n PCXAG-AD). The only drivers that came with the system came on disks date stamped 1991 so the drivers that were on it were horribly out of date (& were an unmitigated disaster to put it mildly :) ) However I noted that the driver software was written by a group called Appian. Does anyone have any info as to any possible ftp sites or actually have these drivers on/with them. At the moment I'm being forced to use the VGA emulation mode & man it is a pain when I'm using AutoCAD to be limited in colours & resolution. Any advice, help suggestions greatly appreciated because if this situation isn't resolved I'll have to go back to DOS ( :( ) Thanks in advance, Stuart Johnsen -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Stuart Johnsen email: s.johnsen@csc.canterbury.ac.nz | + Technician phone: +64 (3) 364 2311 + | CSC, University Of Canterbury fax: +64 (3) 364 2332 | + New Zealand + | | + ? rotide liam eht htiw gniyalp neeb s'taht yugesiw eht s'ohw thgirlA + ^Q^Q ^C^C -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Stuart Johnsen email: s.johnsen@csc.canterbury.ac.nz | + Technician phone: +64 (3) 364 2311 + | CSC, University Of Canterbury fax: +64 (3) 364 2332 | + New Zealand + | | + ? rotide liam eht htiw gniyalp neeb s'taht yugesiw eht s'ohw thgirlA + ^Q^Q ^C^C

There are no TIGA OS/2 drivers, and there never will be. TIGA is effectively dead; Texas Instruments have stopped further development of TIGA. As far as I was ever able to find out, no OS/2 TIGA drivers were ever written. At home, I have a Hercules Graphics Station (anybody want this?) with a TI 34010 chip, and when I switched to OS/2 two years ago I went on a fruitless hunt for drivers. I eventually bought a new video card. At work I had an Artist XJS, a 34020 card. With 7M on the card, it loaded and ran the entire X server itself (I was using Unix). Then we switched to OS/2, and the Artist card had to go; no TIGA drivers. See, the TI 340x0 series is special because it's a fully programmable CPU that happens to excel at graphics. You get performance by dibiding work between the two. (The X Server was an excellent example of how well this works - it was great, and I miss that performance.) But these days, PC graphics hardware is defined by the set of primitives that can be performed by a Windows video driver, and this is a small, fixed set. So the simple blitter accellerators have the whole market now and TIGA has been abandoned. -- Richard Krehbiel rich@kastle.com or richk@netcom.com Nothing witty comes to mind...
