Looking in the Chaintech manual, the POST display is on a 5 1/4" tray mounted display device (Digidoc box). http://www.xbitlabs.com/articles/chipsets/display/nforce3-250_5.html http://www.xbitlabs.com/images/chipsets/nforce3-250/board.jpg You can download a manual from here. POST Codes are on page 154 in Appendix A-1 of Znf3-250.rar (a PDF file when decompressed). http://www.chaintech.com.tw/a41_product_downloads.php?mk=322&sk=&type=pro A "POST Code" is a progress code, indicating what the BIOS is doing at that instant in time. "FF" is the uninitialized value for the display device. If you see "FF" and no other activity, that means the CPU is not executing BIOS code. To interpret what "02" means, you'd need to know what BIOS was used. This site has POST Code values, but my experience is, the values actual users find on their display, are seldom documented. A BIOS designer can add additional code values, that are not recorded anywhere. Which makes the POST Code almost useless for detailed debugging. http://www.bioscentral.com/ (left hand column of links) You could look in the Award POST codes. Maybe the "AWARD Version 6.0" at the bottom of the page are the ones. Code 02 is "Reserved", and like most of the postings of POST symptoms, that means we cannot tell. http://www.bioscentral.com/postcodes/awardbios.htm The Digidoc box displays temperature, after the system is booted, if the appropriate software is loaded to drive the Digidoc box. The Chaintech manual states that when the OS is booted, the display should read FF if all is well (meaning the BIOS must write FF to it, when handing over control to the OS, as the last value it writes to port 80). It is pretty hard for me to guess exactly what software might be writing the 02 - it could be the BIOS. But being a progress code, if the OS boots, the last thing the BIOS should do is write FF. It is a good question where the 02 is coming from. Paul | |||||||||||||
