OT. I have a R440LX which has a 24-pin power connector which is the same physically as a modern ATX connector, but which is wired differently. Presumably anyone who plugged a modern PSU into it would blow up the board or the PSU or both. Intel why yuo do this????

Yes, as some as I get this NOS PSU I will check the wiring and make sure all the voltages are correct.
The motherboard has a detailed manual with all the connector wire voltages listed.

Okay, I put in the NEW PSU and its booting now. It boots into bios on its own.
But the PS/2 keyboard does not work.
I tried both PS/2 ports.
I get a “keyboard error” on boot up.
I think it was error code 0211
The manual reads you can use either port.

Any ideas on how I can get the motherboard to work ?

Well at least the new psu has it booting (of sorts)

What happens if you now set jumper J7E1 to pins 2-3 (forces the system into configuration mode) - does the keyboard work now?

Merged four threads belonging to Intel486dx33 that were all related.

Thank you so kindly...😉

Give a small live linux a shot booting from optical drive or usb port.. It give more info why things aren't. My even pick up a usb keyboard.

Looks like needs the bios configured.

Yeah, setting that jumper has it booting into bios. But the keyboard is not working.
If I put the jump back to 1-2 the computer boot a black screen with error some kind of error.

Any other way to reset the bios to default settings ?

It won’t boot from any device.

Do you have a floppy drive? The earlier screen shot I'm not sure you hooked one up. I don't remember at what point BIOSes became compatible enough to use CD and USB. Right around that time I always carried a floppy for starting an OS install. In fact a few days ago, I installed Win2000 on a dual P2, and I needed the floppies because the CD did not boot on it. Circa ~1997 board I think. But the BIOS has date codes from '99. I think I had updated the BIOS back in the day.

Bah, and when I pulled out one old my Win2000 boot floppies, one of them did not work... oh memories. At least it was a quick fix.

And one more thing, most Linux OS boxed from the store from back then would give you a setup floppy too... just a hint, this was still frequently needed.

Edit: But yeah, if you try to boot modern Linux OS from a live CD/USB, you may need a boot floppy.

Lots of questions. Do you have a suitable ide hdd attached? I don't see any errors for one. Invalid drive type, non operating system etc.......

I tried other single CPU’s of different speeds but the bios still sees them as 133mhz ?
Dual CPU’s appear to be working but at 133mhz too.

The keyboard does not appear to be working at all.
The keylock and num lock dont work either.

USB keyboard does not work either.

Was there ever such a thing as a Pentium II @ 133mhz ?

Do all the keyboard LED's flash shortly after powering on ? If not maybe they are not getting the +5v. Even when KB controllers fail the AT and PS2 KB will usually (but not always) flash all LEDS once if they are getting power.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor.

The keyboard lights flash quickly then turn off. But the num lock and caps lock don’t work ?

How many ps/2 keyboards did you try?
