I've been playing around with an ASUS VL/I-486SV2GX4, Pentium Overdrive 83 @ 100Mhz, Sound Blaster 16 PNP CT2940 and most recent addition ARK1000VL VLB graphics card.
The recent addition of the ARK1000 graphics card proved nice and speedy for DOS, but Windows 3.1 and the ARK1000/2000 driver would cause sudden pauses and slowdowns in any colour mode (higher colour depth = more slowdowns) - the system became unresponsive all of a sudden, you could see graphics being slowly drawn to the screen before suddenly reverting to normal after 30 seconds or so. After some trial and error, disabling hidden refresh in the BIOS ceased the slowdowns in Windows.
A consequence of disabling hidden refresh, however, is playing any sound through the SB16 would lock or crash the system in both DOS games and Windows 3.1. Moving the card around caused some games to run a little longer but would crash within 30 seconds with sound playing.
A similar issue is documented here (same motherboard, same graphics card but more related to noise not lock ups)
I'm a bit stumped, wondered if others had any further suggestions or workarounds with SB16 crashes and/or experiences with the ARK1000 graphics card.
