Hi all, i got a win98 pc with one of those ALS100 Plus ISA soundcards in it.
sound on win98 works fine, and i edited the msdos.sys in order to boot to DOS and installed the dos drivers from vogons. So pc boots and stays on DOS.

I noticed some issues, the card gets detected on boot and assigns the port irq, but the game detects at random

for example im running commander keen 5, and on the boot screen sometimes it detects the card and sometimes it does not, and says pc speaker.
This is always random, i have to exit and run it again, exit and run it again and sometimes it does say sound blaster detected and sometimes pc speaker only

then i tried commander keen 6 and the card never gets detected

then tried bio menace and sometimes it gets detected and sometimes it does not. It detects pc speaker most of the time..and it gives music! but no special fx.

i have it at:
port 220
irq 5
dma1 : 1
dma2 : unused

mpu selected
port 330
irq 10

i wonder why sometimes it detects the card and sometimes it does not in some games i have to exit and launch them 5 times to actually see the card detected.

anyone got this card? i wonder whats going on
