Then my spec draft will make more sense. Basically, you can't tell a vendor that his hardware is broken or he will ignore your efforts from that point on. "It's a question of honour." If, on the other hand, a vendor can claim his products are conforming to the spec by issuing a software update for broken hardware, it is much more likely that the spec gets accepted. > "BIOS must POST video during S3 wakeup.

If the video state is preserved over S3, it doesn't make sense to declare that behaviour non-conformant. > BIOS must do that during normal boot; this should be very little > additional work. Not necessarily. Some BIOSes stay in graphics mode during the whole bootup (at least it seems so) and would have to include additional code to enter 80x25 text mode.
