Folks, I wonder if you have any advice for me. I've got an IBM 5160 board (the 64-256KB variant). After replacing one tantalum cap that was shorting 5V, the thing finally gets to POST. However, it always stops after testing first 64KB RAM. I've tried various configurations of the SW1.3 and .4 switch …

Folks, does someone happen to have BIOS binary for this board? MS-4131G (VLB 486 ALG) ver:2 Friend of mine has it and believes the BIOS might be corrupted. Unfortunately, so far we were not able to find a working BIOS for this board. Thanks!

Some experiments and advanced googling revealed that this is actually an 386SX machine with Tandon's proprietary add-on board for 486. I've plugged in an 486DX2 / 66 and the computer sprung to life. Some facts: - entering setup via Ctrl-Alt-Esc - despite using 486 processor (on the add-on board), it …

Folks, I have purchased relatively cheap Tandon 7488, that was sold as non-functional. First, it was obvious it won't work as it had no memory which was clearly visible on eBay picture - that's why I decided to buy it, hoping it might be relatively easy to fix. However, after the thing arrived, it …

Folks, does someone have the Supersoft ROM post diagnostics for common PC XT? I was able to find versions for IBM machines (https://ibm.retropc.se/supersoft_landmark/Supersoft%20Landmark%20ROM.html) but it seems to be specific for IBM models 51xx. I also found a forum that links the PC XT versions …

It turned out that the setup floppy comes with an install program that allows to change the language after all 😀 So there's no special English setup floppy, it's just one that's multilingual 😀

OK, thanks, I'll look into that document. I was able to boot off the hard drive before it was reformatted. I expected the BIOS will skip the drive as it cannot boot from it and continue with other boot devices, but it obviously doesn't work that way 😀

Folks, do you happen to know how to force XT-IDE BIOS to boot from CF even when a local hard drive is attached? I am reviving another PS/2 Model 30 / 8086. Floppy drive is dead, so I don't have the luxury of booting from it. I have low formatted the hard drive in the system, and now I can't boot …

Folks, does anyone have some more details on Seagate ST-1771? I am guessing it's ESDI for MCA based PS/2 machines, but it would be great if someone could confirm that. Thanks!

Thanks, guys, it looks like I have to stay with DD and eventually add 3.5" DD drive, because I am not sure I'll have enough ISA slots for another controller.

Folks, does the floppy controller in PC-10 support HD floppy drives? I am wondering if it makes any sense to try one of the HD floppy option ROMs, but if the HW shouldn't support it, it would be a waste of time. Thanks!

In the worst case, copy the WinXP files to bootable USB HDD, boot from USB HDD, prepare the HDD (partition/format/sys) if necessary, copy the install files to HDD and start installation from there. I've done something similar in the past.

I'm using 44pin IDE to mSATA convertor in one of older thin client machines, that's probably the cheapest solution (8GB totalled to under 15 bucks or so). https://de.aliexpress.com/item/HIPERDEAL-Advanced-Adapter-mSATA-SSD-To-44-Pin-IDE-Converter-Adapter-As-2-5-Inch-IDE/32818544589.html?spm=a2g0s. …

If you mean the MO drives, I do remember them, I even have four drives (3,5", 230MB and 640MB) and a box of medias. I have used one of the drives recently to install MacOS on an older Mac (Performa 475 or something similar).

Thanks, I vaguely recall seeing that page before. Unfortunately, it didn't help, my PC10-III has totally different mainboard. However, the links lead to some interesting pages where I was able to find something that looks like schematics of my PC10. I didn't have time to analyze them yet, though.
