What's the board part number? Should be written near the memory slots in a form such as XXXXXX-XXX (all numbers).

Or as a crude but often right rule of thumb, what CPU does it have? If it's a MMX* then it's split voltage motherboard, if it's an older MMX-less Pentium then it's single voltage.

*Excluding later diy upgrades, 2.8V MMXs will fit and work in a 3.3V board, even if you aren't supposed to so such a thing.

Thank you. I discovered that I have Pentium 166 without MMX. I succesfully installed and configured new hard drive. Thank you again for help.
