IBM PC 5150 Rev.A (SN101761) is listed on eBay. https://www.ebay.com/itm/126249846768nordt=true

@compaqportableplus Great, thanks for helping! Now, your dumped BIOS image is working on another IBM PC 5150 or emulator correctly.

@compaqportableplus I couldn't even explain that part. ㅑ apologize for any inconvenience, hehehe.

@ compaqportableplus Oops. After running RUN, you may have to wait a few minutes for the results to appear. (Expected to be about 1-2 minutes)

@modem7 What's disappointing is that it doesn't work if you install an EGA/VGA card using extended BIOS, but it works if anyone installs MFM HDC or XT-IDE.

@compaqportableplus Yes, the result is the same as the one I gave you by running the BASIC program. The reason is that I am confident that the sum of the BIOS parts will match the actual machine and the emulator, but I still want to check. When I looked at the checksum byte in the BIOS dump...

@compaqportableplus Thanks. By the way, can you run this BASIC Program on IBM PC 5150 (5000024) finally? I've maid simple BIOS sum program on BASIC. 10 CLS 20 DEF SEG=&HF000 30 A=0:FOR I=&HE000 TO &HFFFF 40 A=A+PEEK(I):NEXT 50 PRINT "SUM : E000-FFFF is";A 60 PRINT "BIOS version is ";:FOR I=0...

Thanks very much! This BIOS may be the 3rd BIOS version. After doing some testing, I found the following. 1) Partial support for expansion cards with BIOS ---> For example, devices such as HDC (Hard Disk Controller) are supported, EGA / VGA cards are not supported. This symptom is the same...

It figured out that MartyPC (8088) emulator doesn't run on Windows 11.

In my opinion, if the graphics card does not fit the PS/2 8530/8525, MDA / CGA / Hercules cards or VGA/SVGA cards that support only 16bit ISA slots are common. OAK OTI-037C chipset-based VGA cards are designed to run smoothly even in 8-bit ISA slots, so in most cases they can be resolved through...

Okay. Personally, it's not because I don't like MartyPC's range of screenshots. As I said, taking a screenshot of the entire area, including overscan, is even more welcome. For reference, I have an IBM PC 5150 / PC XT 5160 motherboard with an 8088 (4.77MHz) CPU and an MDA / CGA / EGA / VGA...

This is screenshof of 8088MPH / PC-Tools R4.30. *From MartyPC emulator *From PCE IBM PC 5150 emulator *From 86box emulator It's a slight difference of 1%, but I'm looking forward to seeing the same results as actual results with a little more modification. But the interesting...

Oh, that's great! Now it works. martypc --configfile 5150128c1.toml

This is an example of a batch file running in my PCE emulator. Example: 5150064c1. BAT --> IBM PC 5150 / RAM: 64KB / CGA / 1st Rev.0 BIOS bin\pce-ibmpc.exe -v -c ibm-pc-5150-1981-04-24-64kb.cfg -g cga -r In the case of PCE, after creating a batch file in this way, in Windows, the batch file...

I edited martypc.toml as follows to add IBM PC 5150 (with Rev.1 BIOS) rom_override = [ { path = "./roms/5700019.u29", address = 0xF6000, offset=0, org="Normal" }, { path = "./roms/5700027.u30", address = 0xF8000, offset=0, org="Normal" }, { path = "./roms/5700035.u31", address = 0xFA000...
