That took quite a while 🥳 The memory test was very revealing, six out of eight of the 8MB SIMMs are faulty, but only in a single memory nibble within the entire 8MB stick. The faulty modules are all Kingston KTC-8000N 70ns FP Parity. So I'm left with two KTC-8000N modules and the 4MB on board for a …

If it fits and solders down it's proper. You can't see the bends anymore after that 😀

You don't really need the extra side bracket if your case has the bottom mounting hole. Is there a plastic circle insert on the underside of your chassis? What you're really missing is the black plastic trim bezel that's supposed to snap around the drives after they are installed

Did you ever check the physical dimensions of the existing toggle switch?

You have the original IBM half-height to full-height mounting brackets. These are "rare" and I would strongly advise not removing them from the system. They require the drive assembly to be inserted through the *rear* of the drive bay not the front. As such, only IBM-spec drives from Alps and YE- …

That's not surprising. The motherboard expects to be controlling the soft power of the PSU when being fed through the ATX connector. I think you should just use the ATX to AT adapter (or better yet source a real "AT" (LPX) PSU)

The deskpro/m has integrated IDE in the IO/audio board under the PSU. I can't comment on running an IDE CDROM on it thought, I use SCSI on mine

"C:\windows\net start", however, displays: "Error 2182: The requested service has already been started.", and doesn't map network drives in DOS. I cannot duplicate this, and it doesn't make sense. Are you saying you ran the command "NET START" for the first and only time at bootup and received this …

You could remove the switch and measure the cutout. Most likely it's the Taiwanese "standard" 25x25mm in which case you're out of luck. If however it was the smaller 22x19mm like the classic macs used, then this switch would work as a replacement: https://www.digikey.com/en/products/detail/e-switch/ …

Why not just replace the latching power switch on the AT case with a momentary one? They are available in the exact same form factor from ebay/aliexpress

Try reinstalling 98 but this time run "setup /p i" this will disable ACPI without any changes to the BIOS or CMOS setup parameters
