A while back I "finished" (does one ever really ?) setting up the hardware side of my "does-it-all" attempt at a retro PC .
Specs : Re: Jack of several trades, master of some (hopefully) .
It seemed to be working well enough, save for lack of NMI support, until I tried Doom and Doom 2 (gog.com purchased versions) with GUS effects and music and realized they always freeze at freeze at "calling DMX_Init" .
On this machine
- there are 3 ISA sound cards (Audiotrix 3DXG and CT3670 being the other two besides an 8MB GUS PnP) with no apparent IRQ or DMA conflicts .
- ISA slots are handled by an ITE ISA bridge
- No ISA bus speed setting is present in BIOS
- Video runs through a PCI Voodoo 3 3000 (also tried with the AGP 6600GT also in the machine)
- OS is Windows 98SE 's pure DOS mode (tested both with and without himem.sys and EMM386)
- Doom works fine with sound effects through either Audiotrix 3DXG's or CT3670's SB compatibility and music through either one's OPL3 implementation (both OPL3s play simultaneously since they both listen on the same port address)
- DOOM midi music works fine through CT3670's MPU401 to an SC88
- GUS compatible demos like Second Reality, Airframe, Dope and EMF's Verses play fine with sound in GUS mode. Vertigo's Nature produces no sound in GUS mode, however .
- GUS PNP uses ULTRASND=240,6,7,11,11 (SB part is disabled, as is CD interface) and second IRQ is set to 0 in iw.ini
- IW.ini is set to legacy mode
- ULTRASOUND patches are installed in c:\gravis\ultrasnd\midi and ULTRADIR=c:\gravis\ultrasnd
- A valid ultrasnd.ini is present and the paths within it are valid .
- Doom is version 1.9 and prepgame.exe has been run .
- Invoking doom.exe through DOS32A does not help .
- Clam AV running under Windows does not find any viruses (viri ?)
Does anyone have any ideas before I start taking out sound cards and pulling out hairs 😀 ?
