michael regoli; mr@cica.indiana.edu asks if an upgraded bios will allow the Zenith 449 card to work as a VGA with WordPerfect. ............. No. This really is an EGA card that will send its signals properly either to a TTL monitor or an analog ("VGA") monitor. It does not have VGA graphics capacity and never will. With WP 5.0 you can use the graphics driver named "EEGA MODE 12H 640X480 16 color" (available separately from the original set of drivers) which is a standard EGA driver with the extended graphics mode 12 added. I have not checked to see how you chose this with WP 5.1. The SETVID command gives you direct software choice of video modes. But only those that it tells you, i.e. EGA, CGA, hercules. Bitch to Zenith, but don't expect much.

Mark Urban-Lurain;urban@cpswh.cps.msu.edu asks about the Z-449 video card switch settings. .................... You should get some documentation from Zenith. Their specififications for monitors changed a bit over time for unrevealed reasons. I looked it up in my docs and find they say: for use with an analog monitor the six switches should be-- (top) 6 -- on 5 -- on 4 -- off 3 -- on 2 -- on (bot) 1 -- off where off is to the left and on to the right. Switch 6 (top) tells the card to use the analog outlet (on) and switch 5 controls automode switching (enabled if on). You must give a command with SETVID to change between color modes (e.g. EGA) and monochrome modes (e.g. hercules)--it won't do this automatically for a program. In addition, jumpered pins P1 must jump pins 1 and 2 for analog (or 2 and 3 for TTL). The SETVID program comes with the video drivers and weak documentation. There is a build in screen saver that you can evoke with SETVID. Don't, it will cause a complete screwup if you try any use of SETVID afterwards under unpredictable conditions. By the way, as someone else remarked, the 640x480 extended EGA mode is (according to the docs) only available with analog monitor output. Hope this helps.
