Well, safe-texture-manager was in the thief2 user.cfg for some possible incompatibilities with TNT2 and old detonators drivers, so problems could always arise even with older hardware/drivers, you have to tinker at least a bit with old software/hardware. In my experience Forceware 45.23 is great for …

I'm using DirectX 8.1 on Windows 98. Thief 2 version is 1.18. Given that 45.23 driver works fine, there is definitely a compatibility issue in 5x.xx drivers. I was able to reproduce the black screen in Thief 2 with 53.04 and 56.64 drivers on my GeForce FX 5900XT. As you say, sometimes Windows will …

I've verified that all the jumpers and resistor networks are configured correctly. I'm using a DX/50, which has been tested in another 486 board, along with the parity RAM and …

V0 was the first released Deskside (1992), dual pentium CPU board does not work on it, for that to work you need a later rev. AM0 or AK0, which have a plcc socket near the bottom right corner of the motherboard, you need to put there a smp enabler pal (it was sold with the dual pentium CPU board) to …

Thank you for the help, the PAS has been fixed and it works quite well, I replaced C92 with a 68nf ceramic cap, there were also a scorched tantalum cap and a 74hc4316 not working properly, replaced both and now the card is working again and the volumes are well balanced. Tested both the pas section …

I acquired a Pro Audio Studio, which sounds almost muted but it is indeed working, I noticed a broken ceramic cap in the op amp lf353 section and it is indeed open circuit. I hope someone here can measure his working cap value so I can fix my card. The cap is C92. Screenshot_20210102-190208_Chrome. …

Old thread resurrection but PC Chips m321 should be based on 82c391/82c392/82c206 Opti-386WB Chipset, here is the datasheet for future reference. The Bus divider options are clk2in/8 or clk2in/6, so with an am386dx40 (80 Mhz crystal) and the 8 divider the actual isa bus is 10Mhz. Input PIN 14 ( …

How do you know ? Can you test the m321 with a bios for that chipset just to make sure ? ^^ If you hex edit a m321 rev.2.7 bios dump you will find references to 82c391/82c391b, regarding the ISA Bus dividers: " This is valid only for 82C391B Chipset. The options are: -Jumper : AT Bus Clock is CPU …
