Recently I bought a STB EM-16 VGA board. It is also sold 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. My system is a 386SX with Pheonix BIOS (Chicony motherboard). I have disabled bios on my drive controller. When the system boots up a different sound beep sound right before bootup, and when my system is up, I can't write to the drive. 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. +-----------------+---------------------------+-----------------------------+ | Bill Poitras | Polygen Corporation | {princeton mit-eddie | | (bill) | Waltham, MA USA | bu sunne}!polygen!bill | | | | bill@polygen.com | +-----------------+---------------------------+-----------------------------+

As it turns out, old EGA used INT 2, and to maintain full compatibility with EGA, so does the STB VGA card. However, INT 2 is used as the cascade interrupt for the slave 8259. The solution might be to move the IRQ2 jumper on the board. On the EM-16 I have, its jumper J3, check your documentation. -- Jeff White | {amdahl|hpda}!bungia!com50!jwhite Com Squared Systems, Inc. | jwhite@c2s.mn.org 2520 Pilot Knob Road | (612) 452-9522 voice Mendota Heights MN 55120 | (612) 452-3607 fax
