    Well, I am not suggesting to switch distros for upgradability. It's just my experience that upgrading is what I usually do but not a big deal either way.

    However, in my experience, I'd be wary...

    Yes, I am aware of the formats. I didn't suggest that a slackware package is just a tar xzf on upgrade either, and I know rpm's and deb's capabilities.

    I've always upgraded from version to version on Slackware Linux. I've been doing it for nearly 20 years, no problem. Being able to upgrade or move hard disks to other machines seemlessly was one of...

    I have come across IBM software that requires PC-DOS 3.3. But if that is something you need, you'd just deal with it.

    It's easy to keep a boot disk for 3.0 and 3.3, if you have both anyway; that's...

    When the school shutdown started here, the lessons were developed in the realm of what the teachers knew what to do, but now online. This is because they had to...

    It might depend on what it's equipped with and what you want to run. I had a Turbo XT with 20MB HD with DOS 3.1/3.3. When DOS 5 and 6 came out, it ran that too. So I don't think it really matters....

    I have seen a CGA card from a 5155 or Compaq that has an internal composite port for this purpose. Is it a composite CRT then? It's what the 5155 had.

    Most EGA cards come with a feature connector header. Is that what you are looking for? What does the connector look like? I'm guessing it uses an RGB signal capable to 15khz/21khz horizontal. Because...

    Yes. The machine will boot to DOS. The POST failure is in the tests performed by the EGA ROM. The machine proceeds and I can use the machine with a second display card, and right now I am using it...

    Yes, it's not hard if you enable USB in the BIOS, install the drivers, and do not have resource conflicts. So for all we know, he just has a bad board.

    OP: I've never seen jumpers needed for USB....

    The github page seems quite useful. But I am a little confused by the write-up. It mentions IRQ 2 as available but "Not allowed by 3C5X9CFG". Actually it is usable by setting IRQ 9, and sticking it...

    I can only run the EGA diagnostics telling the program that I do not have both monitors hooked up. Otherwise it will try to prompt for things on the EGA screen I cannot see.

    Then how can an EGA co-exist with CGA? The manual does say to always set SW1 5=ON 6=ON when the EGA is installed, even as secondary. I think the EGA ROM is supposed to initialize the primary card.

    MD5 of my ROM is the same as yours.

    I can read the switch block setting from RAM. I think the ROM will run, but I think the EGA card is not taking all the initialization settings.
