so far gameplay has been great with EGwhaven... I have found a few very localized places where it slows down. It happens it seems at defined areas and is reproducible. However I am not able to reproduce it in DOSbox... changing the speed of the CPU or disabling cache doesn't have any impact.

I recently purchased an AT power supply like that off Ebay, brand new with better internal protections over buying an old used one... Paid about the same. Depends on your use, for me I was wanting to maintain period correctness. https://www.ebay.com/itm/Replacement-Power-Supply-AT-for-FSP-SPARKLE- …

After some careful reading of this document, it seems that the multiplier bits in "Power-On Configuration Register" (bits 22-25) are read only. They are set according to the CPU pins during power up. This implies that they are set by the motherboard upon booting, perhaps using some external …

Sorry, I meant that neither is able to set the multiplier... Is your PII-400 an engineering sample? Because as far as i can remember, Intel started locking their CPUs from PII Deschutes onwards, and max frequency of Klamath is 300MHz, so your 400MHz CPU should be Deschutes or later which is …

Setmul does seem to change my CPU multi, and running your program with the a switch reports the same... Hi SuperSirLink, Does that mean CPUSPD couldn't change the multiplier but Setmul can? Or do you mean it works the same as Setmul? Hope it's not another bug... Sorry, I meant that neither is able …

just get a cheap multimeter if you don't have one, a $10 one is enough for simple continuity testing don't just "try" with mains voltage :p exactly... It is not like an ATX soft switch you connect to a motherboard... Connect it wrong, best case you blow up the PSU, worst case you start a fire or …

The protrusion is the switch, so black and white are away from the switch... But again, don't assume the position of the terminals on both switches are the same...

You will have to identify what those conductors are. Do you have a multi meter? Please be careful and don't apply mains power till you know for sure what you have. At least one of those lines is high voltage.

I would unscrew the switch from the case, there is a screw holding the silver plate to the face. Then remove that silver plate from the switch. That copper/gold plate of the switch is a standard mounting surface. If you get a new AT power supply it will have that same switch, then screw on the …

I guess it depends on which power supply you want to switch it with. but, I think the on/off switch belongs to the case, not the PSU. I have seen on/off switches that have a special "tiny cap" on the actual on/off switch pin to reach the button on the case and without that tiny little cap, any …

Another stupid question now that i am asking them.. if i want to switch power supplies.. do these 4 things at the power button come off or should i remove the screws and move the entire black box with the 4 still attached? If they come off does it matter in what order i attach them in the other …

You have to remove thrat switch... Any AT power supply will have a switch like that since those lines are A/C... So i do not need to remove the 4 parts connected to it, i have to remove the full black box? I would... keep the switch with the PSU. Not sure if all the pin outs are the same between …

You have to remove that switch... Any AT power supply will have a switch like that since those lines are A/C... Some have spade connectors, but some are hard soldered, so I would just keep it with the PSU... Edit: you could fix that P9 connector if you are comfortable with a soldering iron. There …

Pull the PSU out and see if you can rotate it and lift the rear edge along the rear of the case maybe? Edit: side note, I like the mobo display!

Try putting the screwdriver vertical between the connector and the vertical part of the socket and separate them some. It may be the guide pin is catching and not releasing...
