You've established that it should be a 486X25 it will
recognize up to 64 Megs of ram if you want to buy it.
As it has a overdrive socket, if you can get the manual
you should be able to replace the CPU with a 486X100
And I know it will run a 6.4 Gig HD if you use a
software overlay.
You can run Windows 3.11, Win95, are Win98 if you
use a switch to bypass the need for a co-processor.
I have a 486X33 running win98 with a dual boot,that
takes it to Pc-DOS 7.0 with Win3.11 WFWG's.
yes you can install a CD-ROM in it.
You can do allmost anything a pentium can do BUT a
little slower.........

It's a 486 SX-25 CPU. It could possibly run the equivelant of the game "Doom". If it did have Windows 95 on it, then I would seriously consider downgrading to Windows 3.1 for a few reasons. Number one, that motherboard probably can't handle more than 16 megs of ram. Sure Win 95 could run on that, but it would be unbelievably slow when mixed in with the lack of CPU speed. Number two being that the board probably wouldn't be able to recognize more than about 500 megs of hard drive space (I forget the exact number). Windows 3.1 and most of its software are relatively small, so you could still be comfortable with a smaller hard drive. This is just my opinion though, which reflects my needs and interests in a computer. Yours could be completely different.

As for upgrading, it depends on what you are looking for. It sounds like the board could possibly handle a 486 DX2-66 chip, but you still wouldn't be much better off. I had a 486 with the DX2-66 chip once upon a time, which I replaced with a Pentium board and a 233 MMX processor and was able to have 64 megs of ram, guaranteed. It cost maybe 100 bucks for the board and chip, but the 72 pin ram tends to cost an arm and a leg. I'm not exactly sure how well the present system could handle a CD Rom without knowing the amount of ram and whatnot, but a Pentium system like the forementioned would definitely be able to support it.

at, search the support site using "425" without the quotes, and also underneath, there's a box that has a place for the serial number. your serial number is listed above. this will give you an approximate idea of what's supposed to be in it. this is a 486sx computer. unless somebody's changed something in it, this should be what you have. if in doubt, try checking with them, or the place you got it for more info. it's difficult, but not impossible to check the chip numbers out. but there's more room for error of me giving you the wrong info.

good luck!
