Did you look at the second image? It has a Dallas chip. You can desolder it and put in a socket.

OK NOW I see 😦

I am not sure I would want to get into soldering and desoldering things on a motherboard - you are braver than I would be!

Can anyone who has this board test it with HIMEM for errors? Many thanks!

My one loads HIMEM just fine. Seems to support EDO memory as well.

Thank you. Could you let me know what RAM you are using and which Advanced Chipset BIOS settings you've setup.

This seems to be the memory i'm using: http://www.alldatasheet.com/view.jsp?sSearchw … =KM416C1204AJ-6
Just a pair of 8MB EDO sticks. They are Samsung and have a sticker on them that says "SEC KMM5322204AW-6; KOREA 9631 H"

The CMOS setting I'm using are just the optimal defaults. (The RTC battery is dead.)

Interesting... I'll check my solder work and try putting 256KB of cache back in.

You should desolder your RTC and put in a RTC socket with a new RTC.

I'll probably do that after i get my dual P3 rig working properly.

Well, it wasn't my solder job that was the problem. I swapped out the 15 ns cache for 10 ns cache and no more HIMEM errors. It is possible that the 15 ns modules weren't making great contact with the DIP or that this board is very particular about cache speed for the 512 KB configuration.

My main gripe now with this board is that the BIOS seems to be PS/2 mouse unaware. Be careful not to plug in the ps/2 cable backwards! I thought maybe the manual had reversed the pins, and that is why the mouse wasn't working, so I flipped my cable around, powered up, and saw what I thought was smoke. Since I was specifically watching/smelling for smoke, I was able to power down within 1 second. Everything seems to work still.

I just can't figure why Shuttle put PS/2 headers on all revisions of the HOT-433 but never implemented its function. Did they run out of flash space in the BIOS?

Only $146 for Voodoo cards!! I got five, maybe I should sell them and pay off one of my credit cards 🤣

Edit: whoops! Sorry guys, meant to post in the Outrageously priced retro gear Humor thread.

Yes, please repost to the other thread. This topic has nothing to do with the HOT-433 v4. Btw, all items from that particular seller are ridiculously priced.

There was a guy in Russia on there selling an Asus 486 board with a SIS chipset - one of the nicest 486 boards I have seen - for a reasonable price, but I have pretty much decided not to pursue a 486...

Saw that, but did you check his shipping prices? Ouch!

Could turn out to be a nice deal for someone ( European especially ) looking for a good MPU-401 clone.

Yeah I did - the shipping was as expensive as the board. Still, it would have been cheaper than the $200 I see some board being sold for.
