I'm trying to setup a DOS disk (well it's a CF card but still) that I can use to test various systems with regards to DOS compatibility of PCI cards.
The initial system that I chose as a baseline, to make sure that everything works as it should, is:
motherboard: QDI PlatiniX 4X, chipset i850, with a 1.8GHz P4 and 512MB RDRAM, has PC/PCI connector (which is why I chose it)
sound card: Yamaha DB-XG, YMF744
video card: ATI Rage II AGP and TNT2 M64 AGP (not both at the same time of course)
The SB-Link cable is installed of course.
I'm using the driver from Vogonsdrivers, https://www.vogonsdrivers.com/getfile.php?fil … 693&menustate=0
It installs fine but after reboot when it goes into configuration mode, it allows me to chose only some of the options; many are greyed out. For instance it allows me to choose the base addresses for the SB emulation, FM, MPU401, joystick. But other options for the above, such as the IRQs are greyed out and cannot be altered (all the IRQs in this test system show as 9). More importantly, the DMA channel for the SB emulation is also greyed out and it shows as "disabled", i.e. no DMA channel is assigned for SB.
The sound tests in the setup program pass fine - had to alter the mixer settings a lot, the defaults sounded way too loud and distorted - but I'm worried that with no DMA channel I'll run into trouble when testing with real games. Already I tried X-Wing and it doesn't run unless I disable sound.
FWIW the BLASTER variable that the installation program inserted automatically into autoexec.bat includes a "D1" however its own setup program still shows no DMA channel.
It's off to disk I go,
With a bit and a byte
And a read and a write,
