Dean; Try this site; http://www.intel.com/support/motherboards/identify.htm Your board is identified by the bios number that comes on the screen at boot up, or you can enter setup and see the board number. I believe you can hit the pause/break key to "freeze" the bios screen. You may have to press shift+pause/break, can't remember. the Se440Bx should have B0X1 in the number The Se440Bx-2 should have B2X0 in the number. If I remember right on the boards with onboard sound, the BX-2 board has onboard Yamaha sound as opposed to Crystal sound on the BX <>< Larry Fisk Fisk Computers Fruitvale, Idaho ----- Original Message ----- From: "Dean Kiley" <[log in to unmask]> To: <[log in to unmask]> Sent: Sunday, April 27, 2003 8:48 AM Subject: [PCBUILD] motherboard identity Good day list, I am working on a machine that has an Intel "slot one" motherboard, and there are no specific identifying features anywhere on the board. (bios upgrade is what I have in mind) Recently I visited the Intel website and found a utility that was able to determine the exact board by using the BIOS string. With outside distractions, I failed to save the web page into my favorites list, and now I can no longer seem to locate that page. During POST, the bois string is not displayed long enough to copy it down. I have the board narrowed down to these two, but can't be sure: Intel SE440BX Intel SE440BX-2 The bios upgrades are different for each board, so getting the exact upgrade is what I have in mind instead of ending up with a rather large paper weight!
