- Some ET4000 cards may require this patch, some don't. Some ET4000 will
- run with the present (slightly modernized 1.x) drivers, some will not.
-
- Obviously, the ET4000 boards are not all the same. A driver which gives
- 70Hz with the Mega EVA might give ~~35Hz with the Speedstar - if it
- works at all. Maybe the PLL clocking circuitry is different, since this
- seems to be the only part which is not handled by the ET4000 chip
- itself, because it was invented afterwards (the first ET4000s had half
- a dozen crystal oscillators on them).

-
- Local bus video will be a fast and perhaps cheap solution -- once there
- is a driver for the one and only card which fits into your "local bus"
- slot (note that the "local bus" slots are not standardized).
-
- There are no drivers now, so you either have to wait for drivers or
- have to buy a card which is supported now. Do NEVER buy a card because
- someone tells you "there will be an OS/2 driver real soon now".
