That was my plan - wait for POS updates to cease, then look for some unofficial service pack - I figure some enthusiast will be porting Win7 updates to XP. Until then, I'm content to follow nd22's dialogue of which updates do not work on SSE1 machines.

I have this Tyan S2567 motherboard running dual Tualatin CPUs. While there is an ACPI option to enable in the BIOS, Windows (w2k & XP) complains that my motherboard is not fully ACPI compliant and will not install. To install Windows, I need to tell the Windows installer that I'm using an MPS …

DId you try a slower CPU in the slocket? How about conservative memory timings? EDIT: I had a 440BX system which work stabled with up to dual 850's, but dual 1 GHz chips caused stability issues.

I checked the 3.3 V pins on the entire PCI slot and 3.3 V is reaching the slot, so there must be some other check that the POST card is performing prior to engaging the 3.3 V LED. On the Tyan board, I've noticed that the +12 V LED comes in about a half second before the 3.3 V LED. So there must be …

I put the PCI POST card into another motherboard of the same chipset (Tyan S2567) and, both, the +12V and +3.3V LEDs illuminate. Note that the POST card is installed into a 3.3V PCI slot. There are two 5A linear voltage regulators on the board: RC1585M and SPX1581T5. The 1585 outputs 1.5 V and the …

Motherboard doesn’t show any signs of life. Motherboard is a P3TDE6 (dual Tualatin). It worked a second ago …

I think some chipset sheets mention this, though I haven't found a comprehensive table. Maybe someone can spoon feed us the information. I don't really have motivation to thoroughly research this topic at the moment, nor do I anticipate such motivation being fostered anytime soon.

Many retail boxes can be a kind of compacted to save space. I mean unglued and flattened. Some boxes have a lot of free space inside which can be utilised to store related parts. That is, in fact, what I did 17 years ago. I kept them compacted for a 1 year, then thought to myself, "this is silly - …

Boxed items are great, but the storage space required is 4-fold. At one point in the past, I just said to hell with it, and threw out all the boxes and kept the parts. That was 17 years ago. I'm slowly holding onto boxes again until the point in which my closet won't close, then who knows.

I'm going to try it without a heatsink first and measure the temperature. I see many 486 boards with linear regulators and no heatsink. On this particular board, the adjacent components make it so that I"d need to bend the VRM way down like BastlerMike, or have the heatsink rise up vertically quite …

I decided to map out all 3 options for the VRM (attached) because I was determined to find a VRM in my bin which fit the default pin spacing. I ended up having several which had the same pinout, however Q48 and Q4A have a tighter pin spacing than the units I had. I found one which fit Q4, however …

BastlerMike. OK, so your board didn't naturally come with that LT1584, that is, you added it later and don't recall how you arrived at this part number? 7 A is way overkill. I've seen Am5x86-133 interposer boards with 1 A VRMs. I haven't yet looked at datasheets, but you're saying that the the 1085 …
