Does anyone know what files are used for usb disks? I’m thinking I need to copy another file from 2003 to make the usb work. Did you get this to work? I'm confused what your situation was. Were you able to read GPT partitioned USB drives, JUST not of a certain size, or you could not read any USB …

I ended up finding a GA-7VT880. It's a super rare board, but I found it on a Polish site (I don't read Polish). I didn't have the equipment to replace the caps on the MSI at my new place and didn't want to buy stuff just to find out it doesn't fix the problem anyway. Considering that the MSI board …

It's still not resolved. I just ignored it for a while after trying everything apart from replacing caps that ALL look completely fine. Not to mention, why would it then be 100% stable once inside Windows. Makes no sense. It's got to be some weird BIOS thing. I've had other MSI boards with BIOS …

I have a Windows XP system on an Athlon XP with a Radeon 4670 AGP. I just recently got a CRT to use with the system as I had just been using an LCD that was kind of out of place. The CRT is certainly capable of higher than 60Hz at 1024 x 768. In Windows, I can go to the refresh rate window under …

Because bad caps get better when warm. You can test this theory by unplugging it from power for a day, using hair drier to heat cpu power area and then power on Thanks, I'll try that. I'm also going to try to check the caps. I should mention none of them look bad. But does anyone else here have a …

This motherboard is very annoying! I read one other post on google about someone having a similar issue that was not resolved. Basically what happens is about 50% of the time, the board will lock up on boot or when trying to enter the BIOS. Once the thing boots up, it's perfectly stable. Sometimes …

A problem I always seem to run into is not finding a suitable power supply. I'm doing an Athlon XP system right now. In the past I bought a couple new old stock PSUs on ebay. All had bulging caps. NONE of the sellers ever check. The Athlon XPs need especially large amps on the 5V rail. A new power …

So PCem is a pretty good emulator, but there seems to be no ability (in the menus) to manually enter a CPU speed. You have to select from the pre-defined speeds. I want to know if there's some configuration or hack that will let me enter the exact CPU speed? I want to emulate a 486 AMD Overdrive 133 …

There are examples (in a lab) of relatively low tech (simple) silicon circuits oscillating stable at around 10ghz, that is where the upper wall seems to exist until you get into 3D circuitry. The only argument that holds water is that the architecture would not run the piss poor bloated 64bit code …

If it was possible to run a 386 at several GHz, it would still be slow, as it would spend vast majority of time waiting for memory. 386 lacks cache, and DRAM is still relatively slow. Also, manufacturing a 386 using 7nm technology wouldn't be enough for it to run at GHz frequencies. Yeah, no on- …

The Itanium is about the opposite of the 386 or 486, with completely different architecture and (unlike P6 and later) not even trying to translate that effectively into legacy x86. The 386 and 486 are native CISC CPUs where more modern (P6 onwards) x86 CPUs are RISC with an interpreter shell around …

You mean the little locking nubs on the adapter's AT side? Yes, you should be fine to gently shave them off with a knife. I do it all the time personally. Makes connecting and unconnecting power a breeze. Just make sure when you insert it into the board you use a bit of gentle force to make sure …
