I was looking at this modification which seems to make coppermine possible on slockets with this board (assuming you up date the bios to ones new enough to support) http://krick.3feetunder.com/370mod/

This was my main rig from 1999-2001. Mine also didn't support Coppermines. (I found out the hard way. I had to return an upgrade CPU because it wouldn't work.) Mine ended its life as an audio/video capture machine running Windows 2000 with a 1.4 GHz Celeron (on a PL-iP3/T), 768 MB RAM, a Matrox …

Hi, Was in need of a project so got a ms 6119 motherboard. Have updated the bios to the newest version (slightly unnerving as wasnt 100% sure of model but all's well that ends well!). Mine is not natively coppermine compatible - it's the older revsion. My question is, using a slocket adapter, should …

Hi, Does anyone know if the MSI 6119 intel 440BX-2 ver 1.1 motherboards can be adapted to work with ~1GHz coppermine based P3s/celerons? The MSI site says that if there is a sticker with a 'c' on it near the IO chip it is fine out of the box -- this board doesnt have that. There seem to be some …

Adjusting the input voltage wont change anything as the voltage regulation circuit will regulate it to 3.3v (or 5v). On 486 boards the voltage regulator does not always extend beyond the cpu AKA ISA, Memory and other motherboard components are many times run right off the tap even if the CPU is on …

4v is a little high for a mild OC, I would start at 3.6-3.8 (even 3.5 if it’s there) My experience is that if it’s unstable at 160mhz with a small amount of extra voltage it’s either 1. Motherboard/Cards don’t like 40mhz 2. Memory or Cache doesn’t like 40mhz 3. Inadequate Cooling 4. Motherboard/PSU …

An AMD 5x86 133 (4x33) should be overclockable to 150 (3x50) or 160 (4x40) MHz without overvolting. You'd better try to continue your experiments by under-over-clocking to 120 MHz (3x40) to find out whether your motherboard runs flawless with a 40 MHz FSB or requires some waitstates. Do not forget …

I think this feature will be good and easy to implement. But currently I have too small free time to work even on major functionality, so I am not planning to add POP3/SMTP/IMAP support in nearest releases. The project is open source, and any contributions will be greatly appreciated. Just wanted …

Works well How did you do the power? Did you refit the case for an AT power switch or did you use an ATX power with adapter and use the existing power switch? I used an atx supply with an atx-at adapter. Swapped out the switch in the case button from a momentary switch to a latched switch (just …

Theres several protocols that often use the DE25 connector. Its hard to guess how it was utilized in the facility you reference. RS232 would be point to point and would probably have an endpoint computer with a ton of RS232 ports like you suggest. Such serial hubs do exist. More likely is RS422 or …
