Grab a PS/2 port with bracket from eBay and move the pins in the plug to match your board, should work fine.

Wow, nice find.
What junkyard did you rescue it from? a metal recycle yard, a domestic recycler?
I wish i could find stuff like that, or own a HOT433, seems a great board.

Oh duh! Thanks a bunch! I am a big old dummy and forgot these even existed/it was a standard port. I ordered a PS2 to AT adapter already so I assume i'll use the KB in that and the mouse in the bracket.

It's a general recycling/trash dump which is half commercial and half owned by the town, so it's weird. I happen to live in a part of the USA where people hold onto their old electronics for a long time, I guess. We have a recycling/trash dump near me where people can dump TVs etc, often times people drop off old computers thinking they're worthless. I've gotten a couple loaded Apple II's from there before. This is my first pre-Pentium x86 find there in years and years though. Usually just CRT TVs and one or two P4's.

Hi 2 all, I have Shuttle HOT-433 and try to run Win XP SP3 on 128 EDO RAM, and Pentium Overdrive 83Mhz, but have a problem with DIN keyboard. On the stage after choosing xp core (F5), I change C-Step 486 and copy process begin. After one or two minutes, I take a message "keyboard does not found", but two minutes ago I have pressed OK. So I try native DIN kbd and ps/2 via DIN adapter - unsuccess. In what is the problem? And how to solve it?

^ had the same problem once, keyboard was working during boot but after a while it was dead... I reflowed the keyboard connector on the mobo and all was fixed

So I'm right understand, that you turn off DIN connector from motherboard and then turn it on in it? On what point did this happen? After screen with error or before?

What I mean is that the solder joints on the DIN connector had cracks and the connection to the mobo was lost , that's why I was getting the unresponsive keyboard error. When I applied some fresh solder on the joints all were fixed.

I have a Shuttle HOT-433 v4 as well and although I really haven't had many issues its been reported to be a rather buggy board. don't hold out hope for that PS/2 port because if I remember correctly it just doesn't work.

My Shuttle HOT-433 version without ps/2 port. I have tried two kbd's one native DIN, second ps/2 via DIN adapter, also tried two distributives of Wxp sp2 and Sp3, but the error is the same, - there is no found Keyboard. May be need special driver or try to find PCI - ps/2 kbd/mice card ?

There is no such thing as a PS/2 PCI card. Cards that do offer PS/2 ports are usually just USB cards with a PS2/USB converter onboard. See if there are any broken traces (test thigs with a multimeter), and if not, see if you can replace the keyboard controller. AFAIK the HOT-433 has a socket for an external keyboard/mouse controller, so you could add one and use jumpers to disable the onboard one. Also try reflowing the connector.

But in W98 all is OK, think it is software bug.
About PCI to PS/2 cards, what you say about like this?

Just an USB card with a converter AFAIK. Neither PCI nor ISA exposes some required signals for an external controller. A keyboard there would probably work inside Windows XP (if this board even works on the HOT-443... I have a VIA-based USB card and it refuses to work on my older PCs where a NEC-based one works just fine), but not on DOS or the BIOS.

" I have had nothing but trouble with Shuttle HOT-433 boards. SCSI bus mastering issues and issues with reliable cache operation. I also determined that the HOT-433 boards are not wired correctly for a PS/2 mouse for, neither, the chipset-based PS/2 mouse, nor the dedicated KBC and inverter DIPs." -Feipoa

Feipoa may be the guy to talk to as he has some experence with this board though his opinion of it isnt high. As I said I havnt had many issues with it but then I havnt bothered with the possibly none working ps/2 header or SCSI.

Today or tonight I have tried Win Whistler - no KBD, next w2k - same problem, any ideas :-0

Has anyone seen a photo of a Shuttle HOT-433 v1-3 or v4 with the PS/2 mouse DIN onboard? I have not and am doubtfull that they exist.

No matter what pins you connect a PS/2 mouse to on the "PS/2 mouse" header, it will not work on any version of the HOT-433. The PCB traces to the mouse header do not seem to be going to the right ICs and are missing components. I've been hoping to have time to reverse engineer this, like I've done on other boards, but do not have the time. Read this thread if you think you are up to the challenge. Native PS/2 mouse implementation for 386/486 boards using the keyboard controller

For installation of W2K or later operating systems, there are PCI bus mastering issues which I've noticed with a SCSI controller and, if I recall correctly, a PCI ATA controller. The system will hang up when trying to boot W2K (and probably XP). I beleive the onboard IDE port in PIO mode will work with W2K, but it is awefully slow.

Now I have solve this problem. The last AMI BIOS can detect DIN KBD, but during memory test kbd does not work, but after memory test it works good. Also last Award BIOS detects kbd at any time, but does not support HDD larger then 4Gb, AMI BIOS does not have this bug.

I solved this problem around 2005 because in paper manual wasn't any information about PS/2 port pinout so somwhere on Shuttle HOT motherboard website was this picture

Pin Beschreibung Farbe 1 Farbe 2
1 Data rot weiß
2 nicht belegt - -
3 Ground grün schwarz
4 VCC gelb rot
5 Clock blau gelb
6 nicht belegt - -

And did you get the PS/2 mouse working on the HOT-433?
