That is due to the type of flash memory used in the era, you see there are two types of BIOS flash memory, EPROM (which your board has) and EEPROM EPROM requires a UV light in order to erase it and EEPROM is reprogrammable (aka when you update the BIOS, the old one gets erased and the new one is …

The lowest processor you can go to play some really good quality MP3's in mono and downsampled is a 486/66 in my case

Nope, I just setted up the board to run at 3.3v via the jumper settings and both AMD's I have do work in an other board that I have iirc, maybe the power is not sufficient for the CPU to warm up I guess And tomorrow or the Wednesday I'll try the 25 megs setting to see what happens

What happens when you refit the 486dx2/66 cpu? When I configure it for a 486/66 runs great but that is because I'm using the real 486/66 is your board set to 5v or 3.3V? because the dx2 66 come in 5v and 3.3V so not sure which one you running, 586 is 3.3V only hope your not trying to run them at 5v …

Two weeks before I decided to grab a case that had a 486 motherboard inside, the infamous PC-Chips M919 rev. 3.2 When I got the board from a friend in 2017, it did not work so I putted on a case and forget about it until this year where I installed a 486/66 and most of the components that came from …

According to the service manual, that thing allows use for hard drives up to 2 GB in size, that one being the limit for the BIOS I highly suggest a 4 or 6 gig drive since they have a special jumper config to set them for only two gigs only, same thing happened with the 32 gb limit in later years :3 …

Yes and has to do with the reason that it acts like a computer to manage via a Terminal app by the AUX (Serial) or via the manufacturer's software Also this kind of thing is still going as of today with the newer switches, although they are web based instead of using a software to manage 'em I'm not …

That's a nice piece of network gear you got there. How does it do with switching performance? Well, is not that bad, the issue I have to deal with is the IP issue since unlike my 3com switch, this one assigns his own IP instead of using the one generated by the ICS option in Windows The thing has …

On a real computer use a program called DiskExplorer, it has an option to see the partition of a 9800 hard drive, just hook it up and when you start it from the first time it will tell you to find an image, just click on Cancel, then go to the Extend menu and there's a way to open a physical drive …

Continuation from the first post So, the Seagate drive was a nice upgrade, so what I did is I used a PIII computer to run Acronis on it to copy the contents of the Quantum to the new one and then I installed NFS II (I love Rom Di Prisco's songs on it) to test if the paper jig that I made resisted …
