Is the IRQ properly set? com2 normally uses irq 3, while com1 is on irq4 IRQ is set properly, to 3. (COM1 is set to IRQ 4) Once, to be sure I disabled COM1, it didn't help. maybe the 188 or 189 chips are faulty... Both are tested and they work in other card. Besides I tried several sets of those …

BX300A, could you please attach the BIOS and driver that you used to one of your messages? Thank you. I realize I'm half a decade late to this thread, but windows 98 is more than two decades old, yet we still talk about it. I got it working and thought I should share the files and exact steps here. …

Just throwing this out there... I don't know anything about this particular system. What wattage power supply does the system have and have you tried a different one? I don't think that's the case. I have got a 200W PSU here. And its always not working on the twisted side of cable. I can swap …

Have you set the dipswitch correctly to enable the use of the FPU? I never had any problems with them in any XT motherboard. Yes I did. But PC don't start no matter what position dipswitch has. I bought two 8087-1 on Aliexpress from two different vendors. I saw videos on YouTube that they worked …

You have a good memory. Yeah, I do own it (attached is the dump from this exact machine). It's just a basic Phoenix BIOS, like you said. Any will do. However I would go with Super PC Turbo XT BIOS (https://www.phatcode.net/downloads.php?id=101 https://github.com/virtualxt/pcxtbios ) as it's semi- …
