I was trying to suggest that your problem may be related to the bios, not
to the video driver.

Since my last mail, I've been playing around and I seem to have eradicated
my cold boot blank screen problem by turning off the power saving facilities
in the bios. You have first of all a general flag to enable/disable these
power standby/shutdown features, and when enabled, there are a further
half dozen or so separate flags, one for the screen, and one also for
the hard disk drive. It is this latter one which may be causing your
problem if these options are enabled. My bios version is from August 98.

To turn off these features, I first enabled the main flag, then disabled
all the separate options, then disabled the main flag itself. These flags
were all disabled at first, I had no problems then, and then enabled the
flags for the screen and that is when the cold boot problem showed up for 
me. Another suggestion is to short the CMOS backup jumper to revert to
default settings to make sure you're starting fresh.

Starting fresh may be a good idea as I noticed something strange also about 
the bios settings - you can change them,
write and quit the bios, reboot, the new settings are as set in the bios,
but the *effects* of the settings only seems to come into play when you
power off completely and boot up again. That is, changing the bios settings,
writing, saving, quitting, and pressing the soft reset button on the front
panel will reboot and show you the new settings, but they don't actually
work till you power off and on again. Maybe it's something to do with a 
"load bios in RAM" option that is also on in the bios, but seems like the bios
settings are only written to CMOS during (or after?) a power down. I'm
still investigating this one.

Other than that, the PCChips mobo is proving good value for money!!
