Does board comes with a one-time-programmable (OTP) EPROM chip? If so, it seems unlikely it became corrupt.

My objective of getting this board was to be able to run a Cyrix 6x86 at 80 MHz. I'm almost there, but not quite. I am stuck again. I think the issues are BIOS related. Does anyone have newer BIOSes for this board? The issues I'm having with the BIOSes are as follows: Original Phoenix BIOS from 1/25 …

How long should liquid metal last on an Opteron 185 in comparison to what was on the Opteron from the factory?

This is useful information, thanks guys. I was unable to remove the heatsink without risking damage. I intend to return the two cards, so I didn't want to push it. Sounds like these cards in particular have passed their shelf life. This is unfortunate. I really hoped to get a fairly high-end AGP PRO …

I was able to boot the system using the latest AWARD BIOS, however, there is a caveat, you cannot use this CMOS setting: L2: Write-back and L2 bit length: 7-bit This is the default setting though. WT + 7bit, WT + 8bit, and WB + 8bit all work though. I'm not sure what is up with WB + 7bit. I then …

If not, you can still run the SXL or SXL2 at 2x20 MHz.

I took the heatsink off just for the photo. Yes, I plan on removing the label. Yes, I waited a few minutes. I waited an hour even. It just hangs up. The floppy disk light stays on for about 1 minute, then goes out. I've used this boot disk with dozens of other systems without incident. I haven't …

I've tried the RAM that was in the board when I bought it. I haven't checked to see if it is EDO or FPM. I did try two sticks of what I know is FPM. These sticks I use for testing in general and haven't had an issue. Are there some socket 5 boards which only accept EDO? I can hunt down some EDO-only …
ECS SI54P-AIO hangs on boot - help!
Posted on 2018-12-15, 17:55
I'm working on an ECS SI54P-AIO rev 1.3 motherboard at the moment. While on first glance it appears to be working, it won't complete boot. The system passes HIMEM, then just stops. The only item in the startup files is HIMEM, but I've tried bypassing all startup files by pressing F5 at boot and the …

Serpent Rider, I appreciate your valuable insight. My gut tells me its not a motherboard issue (I realise that is not very scientific). I suspect both conditions you mention may be at play. The first pair of cards have fairly common memory related artifact issues. The second pair of cards may be the …

What I have discovered upon probing the CLK2 coming into the CPU is that "clock doubling" really means, "not clock halving". It seems that every 386 CPU is really passing the incoming clock frequency through some sort of PLL divisor of 2. What is interesting is that I think it passes though another …

I'm pretty sure that my dual Tualatin boards (based on HEsl chipset), Tyan Thunder S2567 and SuperMicro P3TDE6, are the only boards I have which sport an AGP PRO slot. I have an Intel S875WP1-E motherboard, but it only contains a regular AGP slot. One other interesting factor about the second pair …
Re: Resistor pack soldered to IDE connector on socket 5 motherboard
Posted on 2018-12-15, 00:33
The black wire just connects to Vcc, so the resistor arrays are pull-ups as Tiido suggested. I'm just wondering why its there. My first thought was also wondering if it was some hack to lessen or prevent the CMD corruption bug.

I have been having the most difficult of times getting an ATI FireGL X1 256M APGro card working. I have had 4 cards in total.

Resistor pack soldered to IDE connector on socket 5 motherboard
Posted on 2018-12-14, 12:50
I have an Asus PCI/I-P54SP4 Rev. 1.5 socket 5 motherboard. On the bottom of the motherboard, there appears to be two resistor packs soldered to the pins of the primary IDE connector. It looks like some kind of after thought, either by the end-user or the factory. Does anyone else have a motherboard …
Re: Date of last update for XP Pro on non-SSE machines
Posted on 2018-12-14, 06:33
Although I still use older systems on relatively recent OS, I've never been aware about a SSE1 CPU requirements for any Microsoft . This is probably because almost nobody would have been running a K6-III on XP this late in the course of time - something you've already alluded to. I don't recall if …

My best guess is that the heat transfer compound used on these particular series of CPUs was more prone to degradation with time. But why more so than others? Perhaps AMD realised the heat generation potential of these chips and used a compound with greater thermal transfer properties at the expense …

Dang, that sucks but great to see it repaired and working again - could you post a picture of the traces/fix? This is what the board looked like on eBay. It has these red arrows pointing to something on the PCB, however I am unable to determine what, or even if there was damage. Arrows_1.jpg Arrows …

Interesting to see the subtle differences. Yours has a blue patch cable near U1E1, whereas mine has a black patch cable near the clock gen chip. Yours is also missing U1E1, while my board has this component installed. Yours has the standard KBC DIN, while mine has the minis. If I ever put mine into …
