Wenas. I have a couple of c-media CMI8738/PCI-SX cards one it's the 037D-GS revision (Hercules gamesurround muse LT) and the other one is the 037D revision (chinese clone).
My motherboard is an intel 810 based soyo sy-7iwm/l. I don't get FM neither in dos nor on windows 98 with the VXD driver. I'm initializing the card with setaudio in dos before loading windows. SFX (PCM) work with some games even in dos. I cannot get FM to work using remapcmi either, my base address is c000.
Now i want to enable FM writing to the pci register using peritool.
According to the datasheet (CMI8738_spec_v06_reg.doc)
Micellaneous Control Register Address 18H
Bit(s) R/W Name Description
19 FM_EN Legacy FM enable
And according to this Re: I've got the OPL3 synth from a CMI8738 working in Windows 7 x64
i need to poke 08 to the c01a address. Is that right? And why? I still don't know how to use peritool. Thanks.
