- :-) Glad it works for you :-)

- There seem to be a variety of problems getting various "ET4000" cards to
- work properly with particular card/monitor combos. Diamond seems to be
- problematic, for instance, and people with Orchid cards have had problems
- with the Orchid drivers, ironically enough.
-
- It seems to be important to have the monitor/card combo set up properly
- which may involve setting jumpers for "Zero wait states" or "turbo"
- options, and of course the bus speed may be messing some people up - if
- you are running with the bus at high MHz, the card may not be keeping
- up. This certainly causes problems for any peripheral that is not
- certified to work with >AT bus speeds.
-
- Strangely enough, with a "generic" ET4000, I have only been able to use
- the Orchid beta drivers (proii4,proii8) by first deleting the SVGADATA.PMI
- file first, then booting up with the new driver. I had to then re-do the
- SVGA ON protocol, of course, and everything is OK now. What exactly is
- causing these glitches and problems is unclear to me, so "whatever works"
- seems to be the technique, as you have found.
