Hi, because 440LX Boards have AGP and I want to design a Retro-PC with a main PCI-Gfx Card and do not want to wast a slot,
I am currently searching for an 440FX Mainboard for a Pentium2 Klamath (300Mhz), I want to change the settings through the
bios from 2x66 (133Mhz) to 4,5x66 (300Mh).

Do you know a Board for my purpose?

Thx
Doc

I know Intel had such a board. I found one at a thrift store a couple years ago. It came with 4 SIMM sockets and no AGP.
I packed the board away, but it was probably something with 440FX.

I do remember something about this board officially supporting 266MHz at the most, but perhaps a 300MHz will work just fine anyway (Intel boards can be picky regarding newer CPUs, but since there was indeed a 300MHz Klamath, it might simply work...or it wont 😜).

MOBOT-Search-Engine only shows one intel440fx Board.
Can someone confirm, that it can use a PII-300 Klamath and does not require Jumpering on the mainboard for changing between 2x66 and 4.5x66?

Thx VERY MUCH!

It has to be jumpered, so no manipulation of the cpu-clock and bus-speed over the bios 🙁

What I need is a Bios feature that is called "SOFT CPU MENU". I think Abit has some Boards with it.
I do not need an AGP Port, but I need the full 7 expansion-slots. PCI/ISA (5/2; 4/3; 3/4).
I can change between Catweasel ISA or PCI, or Network-Card ISA/PCI, so ever combination
is possible.

AFAIK the boards from that era will not give you the full 7 slots (apart from AGP). There are many boards with 5PCI+2ISA, 4PCI+3ISA, 6PCI+1ISA, but usually you can't use all 7 at the same time, as the last PCI and the first ISA are usually shared, i.e. you can use one or the other but not both at the same time. In other words, you can use a maximum of 6 of the 7 slots at the same time. I don't know of any motherboards where you can use all 7 slots simultaneously, unless you look into server boards that have more than one chipset and thus have overall more than 7 slots. I may be wrong though.

Check eBay for Tyan boards and go from there, they are not cheap but sometimes you can get lucky. Got one of these and the onboard ide doesn't do ata spec but only pio mode and it absolutely crawls so you will want a ide or a sata card. http://www.tyan.com/archive/products/html/tahoe2atx.html

Look for a Intel AL440LX as it might be what you need, try to find one with the onboard yamaha as it has real opl3 and some boards will have the general midi option as well (hell of a lot cheaper than other good dos gear).
