In an example I have here it is like this for keys 1,2,3,4,5,s,x: "CHOICE /C:12345sx /N" There are different implementations of 'choice' in Windows. Edit: removed attachment, did not notice this is DosBox specific.

The intel motherboard autodetects the CPU to fit with a 100MHz bus. See: SR440BX review on vogons On the MS6905 slotket, the only Bus speed related jumper is for forcing a 100MHz bus request. Three options: 1) Modify motherboard like I did. 2) Modify slotket to do the same (preferable) (3) …

There is also a "PowerWave 32 Pro" out there with just the CS9233 on it. That card's driver would be good to have. Found the PowerWave 32 Pro driver here: ftp://ftp.dyu.edu.tw/pub/Hardware/stuff/multimedia/PowerWave32/ Like I said, it is a midi-only ISA card based on the CS9233. The DOS driver name …

This SC8000 has quite a diferent chipset compared to any SC8500. Drivers are badly needed for both of the cards but it seems impossible to find them. I always wondered if it would be possible to make a standalone SAM9233/CS9233 DOS initializer tool. By maybe running the Terratec Maestro 32/96 driver …

The way I understood it; Creative labs could not get a SB16 software emulation ready. Put their bets on the AWE64D with SB-Link instead, then urged motherboard makers to support the SB-Link interface. Around that time they sued and then bought Ensoniq. Ensoniq had their AudioPCI with legacy software …

You may be talking about something different. I meant to say that at full processor speed the SB16 emulation was fine. Then disabling L1 cache on such a fast system gives a 486 like system speed, which is useful in DOS. It is with L1 disabled that the SB16 emulation became garbled.

Some PCI sound caveat, that I could not find in my quick reading of this topic. I had this Athlon XP on a VIA motherboard with a SB-Live! PCI soundcard. The SB16 emulation actually worked, until you tried to disable the L1 cache for a CPU slowdown; then the SB16 emulation gave garbled output. …

The analog circuitry of this card is on an analog 'island' on the PCB, which has a different ground plain. On the picture that is on the top right. You can see there is one small chip bridging over to this area, which should be a DAC (8 legs). Then between the DAC and the Jackplug is another chip …

@m5215tx The CPU is not unstable, since an unstable CPU would have locked up. What particular SetMul switch causes the problem, is it the downclocking or the disabling of caches?

Neither seem to work; my video options are still limited to those that shipped (640x800, 800x600, 1024x768).

@Ampera It is never really about what multipliers a particular motherboard supports, it is about what multipliers a particular CPU supports. If you can get a 486DX4-100 running at 1x or 2.5x I would love to see details and/or a SpeedSys screenshot of that.

So I don't think you can downclock at DX4/100 to DX2/66 or DX/25. As you and Ampera can see here: 486 VLB UMC-Chipset, what is it? . Both my Intel and AMD 486 DX4 can be jumpered for either 2x or 3x clock, so 66 or 100MHz. 33MHz was only possible with my true 486DX-33 and with the Cx5x86-100GP ( …

The PII is kind of underwhelming compared to a 233 MMX or SS7 options The Klamath PII core itself is practically still a Pentium MMX. Not much benefit in itself. The Deschutes is the same but runs cooler, which is a very welcome feature. The main Pentium II selling point for gaming is not the CPU …

It should work. In this topic: VIA C3 Nehemiah vs. Coppermine(-128) and Tualatin. The VIA C3 compatibility of the SE440BX-2 Motherboard is demonstrated. With BIOS version P13 that is. For earlier VIA C3 models 'Samuel' and 'Ezra', like yours, most Slotkets will work.
