Ok, the battery should be 3.3v if it's the "button cell" type, and anything over 3.0v should be enough. So.....your BIOS is probably bad. Flashing usually won't help, you probably need a new chip. I don't see where you tried to clear the CMOS, so do that first. Short the appropriate jumper for several seconds with the PC UNPLUGGED.
You can't "recover" from it, whatever the settings were in the BIOS is lost, they just have to be entered again (if flashing fixes it) or after you get a new chip. Now getting a new chip can sometimes be more expensive that the board itself. You'll have to contact Tyan and see what the $ would be. First try and flash it. You need to get the .exe flash program from Tyan, as well as the .bin or .rom BIOS file. The exact procedure is at Tyan's website. Be SURE you set the CMOS jumper correctly for flashing, then set it back afterwards. My PC is messed up now and I can't get to any websites. If you can't find what you need, LMK. -Clint God Bless Us All Clint Hamilton, Owner http://OrpheusComputing.com � ----- Original Message ----- From: <[EMAIL PROTECTED]> Clint: Thanks for your reply. I only recorded one previous reply to my message and I did then check the battery. It had more than three volts, and was good. I should have mentioned that in my last message. I was hoping to find someone who had experienced a failed ROM BIOS and could advise how they recovered from it. At turn-on, the only message is that the ROM BIOS checksum has failed. There is no way to get to the CMOS set up by pressing delete etc. All you can do is boot to the prompt from the A: drive. The c: drive is not seen and when you try to extract information to the A: drive, the computer will not let you write to it. ( I tried to use a CMOS save and recovery program). My access to the Internet is tenuous with Juno and a slow 486 computer, but I will try, and see what information I can get from the Tyan web site.
