Recently I bought a STB EM-16 VGA board.  It is also sold as the PowerGraph
VGA board.  It is based on the Tseng Labs 4000 chipset and uses AMI Bios. It
has 1MB on board.  It comes with great drivers (640x480x256,800x600x256,
1024x768x256) for windows 3.0.  My problem:  I have a WD1006/SR2 (RLL) HD/FD
controller, and a ST277R (65M) drive.  a Chicony 386SX motherboard with Pheonix 
BIOS.  I have disabled bios on my drive controller so the system gets the 
drive parameters from the CMOS setup.  When the system boots the bootup beep is
different from the normal bootup beep.  Kind of like a system error, but no
error message is given.  When my system comes up, I can't write to the drive.  
DOS gives me "Write error writing to drive C...".  When I replace my VGA card
with my old EGA card, the problem goes away.  Is this a problem with my
VGA card?  Or is this just a incompatibility between the Tseng labs chip set
and my controller.  Any help would greatly be appreciated.
