I am planning to install SCO unix on my PC. I have a graphic adapter based on the TSENG ET 4000 chip. Does this work with SCO unix ? . -- ------------------------------------------------------------------------------- Knut Alfredsen | Mail : knutta@lise.unit.no Division of Hydraulic Engineering | Phone : +47 7 59 4749 Norwegian Institute of Technology | Fax : +47 7 59 1289

Does this work with SCO unix ? Yes and No... I have an Orchid ProDesigner II SVGA card also based on the ET4000, running under SCO ODT 1.0.0 . The ODT driver is written for the older ProDesigner which uses an ET3000 chip. This combination will work fine at 640x480. It will also operate at the 800x600 resolution, but with noticeable flicker. It will not operate at 1024x768. I called both SCO, and Orchid and they both claim that they are working on a new device driver for the ET4000. No one seems to know if ODT 1.1 will include it. --Santiago Newbery

However, the ET3000 grafinfo files should work fine at all resolutions up to 800x600. If you want gory details about why 1024x768 isn't supported on ET4000 cards, send me some e-mail. I was unaware that use of the 800x600 mode produced flicker on ET4000 cards; there is at least one ET4000 VGA card in use internally (Sigma Legend) that does not produce flicker in this mode. This card is hooked up to a Sony CPD-1304HG monitor. Could the flicker you observe on your system be attributed to the monitor you're using?

They operate at up to 800x600 with selectable refresh rates. They do not have support for 1Kx768 mode.
