Bad news: I got burned on that Voodoo 5. First time in over two years in this hobby I've made an advance payment and of course it turned out to be a scam. Speaking about that, I had to buy three Voodoo2 cards in the last weeks to get one that was actually working. The first two were sold as …

Done mostly with putting all parts back together. Added an ESS 1869F sound card with a Dreamblaster S2. On the secondary IDE port of the sound card, I'm going to connect a slot bracket with external CF card access (already ordered). Hard disk is still a problem, since the BIOS has E-CHS only, no LBA …

And if the cable is connected backwards, it's not a problem either. Since the inner two are GND, it will only swap the channels.

Depends on the MOD player. The FPU can be used for interpolation or oversampling, for example. But it's not automatically used only because it's there. If the MOD player has no FPU support, it's simply not used. I'm pretty sure Inertia Player uses the FPU if present and also supports Adlib.

Or just use the modern UDVD2.SYS / XDVD2.SYS, which takes almost no memory, supports SATA, caching, and what not. I only use that since I found about it.

Why don't you just try it? Use cutemouse, which will probably detect whatever protocol the mouse uses.

Based on the larger notch that those modules are supposed to have, I found a 4 MB module. May have others, but have to check.

FPM with parity, 36-bit wouldn't be a problem, have many of these. But what else? 5V or 3.3V? Single bank or dual bank? (not to be confused with single-sided or doubled-sided)

No, the brown slot is VLB and for a PCMCIA controller only. Well, it could be used for other cards, but the connector is custom due to the size of the whole thing and EPSON only made a PCMCIA controller card for it. There's no L2 cache, but that only costs about 10% of performance. It's something …

It has two chips in order to support 4 displays. There's no SLI or something (the G450 has no such feature).

Not sure how rare they are. I own one with the FDIV bug as well. But given that Intel replaced them for free with bug-free ones, I assume there aren't that many still around.

Although the motherboard has a Turbo LED header, there is no Turbo switch header on the motherboard. However, via the keyboard shortcut (Ctrl & Alt & + and Ctrl & Alt & -) this system did actually slow down to the equivalent speed of around a 486DX 33 MHz. All mainboards with a turbo LED but no …

While this is great, it would have been so easy to find out which voltages go to which pins without having a working PSU, since it's known where the voltages are used on the ISA slots: B01 GND B03 +5V B06 -5V B07 -12V B09 +12V One minute with a continuity tester and you have it.

The CPU is from my own collection however... Does that one have the FDIV bug? IMG_0660r.jpg Yes it has. Try Dr. Hardware, which actually tests for the bug. In that screenshot, it seems the tool doesn't even detect the presence of the FDIV opcode. Could be of course that the BIOS knowns about the …
