That was the very first question I had when dealing with "plus" models of K6, actually. I've asked it here , and the consensus of that short thread seemed to be "it's okay as long as you use adequate cooling". Besides, there aren't many SS7 motherboards that support voltages lower than 2.0v anyhow. …

The hard disk is availabe/detected in the fdisk DOS command, but I do some partition, when the computer resets to proceed with the format of the new partitions , there is no partitions: the table of parttions is never saved ¿¿?? I have experienced such, too. Often this can easily be solved by …

There is no way a 286/386/486 will detect the capacity of a SATA drive. This is more a capacity than an interface problem. Your best chance is to make use of the XT-IDE BIOS, can be done on a NIC but better on an actual card since your m/b doesn't have an IDE controller anyway. I do not care that " …

I would like to use a mechanical Hard disk (no SSD) with my older motherboards (286, 386). As you know actually there is not available mechanical IDE Hard disk. I thought in SATA HD with SATA to IDE adapter. It works properly in my Pentium / 486 motherboards with integrated IDE controllers, but if …

From practical experience If you use an old configuration program , you can only select 8, 16 or 32k devices. If you use an old configuration program on a 509B, chosing 32k device will result in a 16k window as per the hardware design. mdog69, where can I get the "new version"? I have got the old …

Hi again!! First , thanks a everyone to respond. I think there is a problem with these "bigger" chips.

Hi! I got negative result with compatibility W27E512-70 and 3COM 3C509B-C . I programed the W27E512-70 with the BIOS (version BETA 2.0.0.3+). This picture was taken when I read the chip to verify. https://i.ibb.co/hR24XcB/Chip-Grabado.png The chip was plugged in the 3COM boot socket: https://i.ibb. …

Is it possible to use a W27E512-70 (64k x8) chip in the 3COM boot ROM socket (32kx8) to store Universal XTIDE ROM? If the answer is YES , is it neccesary to copy 12KB ROM four times to fill the 64KB memory or it is enought with filling with "0"s?

Did you try simply hitting F1? Might simply be due to CMOS without valid data. Else you should trace the connections from the keyboard connector to the keyboard controller with a multimeter in continuity and see if there is some broken trace due to battery corrosion. The board hasn't got a jumper …

SIPP will be tough. But you can take 30pin SIMM modules and solder pins to them...

Before doing anything else you shoudl remove the battery ;-) Although the battery is working properly (the mobo saves the date/time/settings OK) , Yes, I'm going to change it tomorrow.
