Thread: Windows 3.0 VGA color driver for 8088/XT

  1. #1

    Default Windows 3.0 VGA color driver for 8088/XT

    I've patched the Windows 3.0 VGA color driver to work on the 8088/86. The file in the ZIP is named VGATEST.DRV and is just a drop-in replacement for the standard VGA.DRV. If anyone tests this or runs into issues let me know and I'll see what I can do.

    I'm assuming it was patched because the stock driver required a 286? V20? Extended ram?

    That is correct, the original driver has 80186+ instructions in it.

    Yea, V30 was required for my model 25 to use the VGA driver when I had a VGA card installed (and hooked up to it's internal CRT).

    Oddly it says MCGA requires a 286 also, but that is definitely NOT true. Works fine with a regular 8086.

    Wow, that sounds great to me.
    I'll install Windows 3.0 on PCE Emulator (IBM 5150 BIOS with Standard IBM VGA Mode) later.

    Hey that's what I used, along with a bunch of other tools.

    I just found a bug in another BitBLT stack compiler. It'll take some time for me to fix it, so refrain from using this in the meantime.

    FTFY.

    Does it just lock up on an 8088/8086 or does it actually give an error message?

    The bug's been fixed; you may use this updated driver.

    The MS driver doesn't push an error message though, it just loads the splash screen and hangs.

    I know this is a bit of a gravedigging post, but I've just tried this driver on actual hardware (an Amstrad PC 5086, 8086 CPU, 640kB ram, VGA card and Windows 3.0) and it actually worked. I'm impressed, and thanks!
