Considering the photo on theretroweb is not showing a 3v VRM. Could you post a photo of your mainboard front & back, just the mainboard, no cpu, no memory, no expansion cards? thanks. Ok, so from the photos, it's clear there is a vrm onboard, an MIC 29302BT and the memory module is FPM, siemens …

the way I see it brown is Mouse data red is ground green is mouse clk yellow is +5v The way the ps2 connector mainboard plug is populated should be fine.

One more photo of the back ( were the wires come in ) of the ps2 connector would've made it possible to verify the connections.

I wouldn't. your dx4 cpu says 3volt. I do not see any VRM on your mainboard, nor any option for it, nor any mention of support for 3v cpus in the manual. edit: the max FSB supported by the mainboard might very well be 66MHz. but the DX4 cpu only has an FSB of 33MHZ, same as a DX2 or a DX running at …

Will you post a photo, front & back, of the dx4 cpu ? fyi, a 100MHz cpu is just a triple clocked 33MHz one. and The manual mentions the mainboard supports 16MB simm modules, both 30 pin & 72 pin as well as dx4 cpu support on both the VL and VL/PCI version.

2. most likely those voltages were used for the serial ports. and likely also for the expansion unit ISA slots.

Out of curiosity... can you post a photo of the mainboard and indicate which one of those is the turbo button connector? edit: nevermind, had another look at the TRW page and found it 😀 and, speedsys is a nice test. ( n )

Have you tried a CD-image file ? What info you just gave lends me to think you selected dvd image file which could have some filesystem software issues.

? Do you mean win98 doesn't support USB CD/DVD drive ? The iodd normally emulates a usb cd/dvd drive and/or a usb hdd, with the contents of the cd/dvd drive being dependent on what image is selected for the drive on the iodd device.

I have a question about this case, and I'm glad you had it as well. I haven't had that case for years so can't remember the specifics, but yeah it doesn't seem to be standard. Usually how it works in my experience is that the case switch connects to the motherboard's 'turbo switch' header, and the …
