Re: Is a small increase in FSB speed worth it?

It's a Gateway OEM version of the Intel i815EEA motherboard, swapped into an older Slot 1 P3 Gateway case. I hope that you will benchmark both the 1100/100 and the 1000/133 and report back here - I, for one, am curious after the difference. If you'd like to get an idea of how much a 133FSB Pentium …

I’ve noticed when entering the bios setup instead of showing the setup screen in one go it draws the interface line by line (although it only takes a few seconds).

I measured the voltages from the 4 pin moltex connectors and they were within range. I went and tried the original power supply again and lo and behold... keyboard works So maybe the fault is with the motherboard cap?

Hello fellow vogons I booted up my Am486 DX4-100 for the first time in 12 months and was met with an unfortunate surprise. Up until now the system has been rock solid but on boot the system would not fully complete its POST ritual. I power on the system, and it emits a single beep It completes its …

Greetings fellow Vogons I've got some 72pin ram I might buy for my 486 but I can't determine if it is EDO or FPM ram. I've attached a picture. Anyone know how I can find out? The seller has no idea. Thanks

Bump. This would be great.. I have an MT32 and both versions of the game. Would love to hear the MT32 compositions on the CD version.

It’s a pretty clean board to be honest. No signs of oxidation or corrosion. I’ll clean it some more regardless 😒 An external programmer is way out of my league at this point in my retro career. Maybe in a few years... Does anyone know how to ascertain what KB size those 25 chips will be? There is no …

Ok so I rebooted 10 times. The 10th time it booted fine. All other times I got the XMS errors with the following addresses (in order) 00166794h x3 001663d4h 00166310h x4 00166190h x2 When it does boot successfully and I run cachechk I get these results:

OK I reinstalled the cache. I seem to be frequently getting the XMS error at boot. Initially it was loading dos fine, other times it will error out..

Thanks. The ram SIMMS are definitely all the same type (even when I swap them all out for another brand). I'll give the sockets all a good soaking with ISO Alc. The 386 cache chips which I was considering using as replacements are 25ns but the onces I removed from the board appear to be 15ns. Will …

The turbo headers have nothing attached at the moment. I'll double check the bios, but I am pretty sure having the turbo enabled/disabled has no effect. Also, I tried disabling the internal cache and the "RAM at megabyte #3 is REALLY slow" cachechk message went away... Is this motherboard spitting …

OK so I've removed all the cachechips and still getting the slow RAM at megabyte #3 message. However, when I enabled the external cache in the bios and rebooted it is now saying I have 512KB installed after post!? (prior it was 256KB, when enabled)

OK so I just ran CacheChk with my external cache disabled and internal enabled. Why would it not pick up my L1? Also is the "It looks like RAM at megabyte #3 is REALLY slow!" message to do with my external cache? I tried swapping out all the ram modules and got the same result. Cheers
