    IBM 5150 08/16/82 BIOS - Has anyone ever seen this?

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

    IBM 5150 08/16/82 BIOS - Has anyone ever seen this?

    @ 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)

    IBM 5150 08/16/82 BIOS - Has anyone ever seen this?

    @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.

    IBM 5150 08/16/82 BIOS - Has anyone ever seen this?

    @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...

    IBM 5150 08/16/82 BIOS - Has anyone ever seen this?

    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...

    PS/2 does not seem to like OAK VGA

    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...

    MartyPC, IBM PC 5150 / XT 5160 emulator

    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...

    @GloriousCow I use PCE 5150 emulator. The format of Disk copy protected sector images are various. I use .PSI image mainly. In general, Disk Copy Protected Disk takes an image dump from FDC connected to USB and floppy drives such as SCP (Super Card Pro), Greaseweazle, and Kryoflux, and...

    IBM PC 5150 Rev.A (Early S/N : 0101876)

    There is even an offer option, so if you do well, you can buy it even cheaper,. But the downside is that seller can't ship it, so you have to go to New Jersey to pick it up.
