Try resetting the BIOS by removing the CMOS battery for a few minutes...make sure to unplug the power cord 1st, or the BIOS may not clear. Reinstall the battery, then try to bootup...

I have removed the cmos battery and then reinstalled it. But I am still unable to cross the initial booting screen. Keyboard is not getting activated. I could find a difference in the display when booted the system with out keyboard.

Hi All, I could solve my problem with connecting a usb keyboard and was able to access the bios. But, If I connect usb keyboard , bios is not detecting the 40 gb hdd. I could restore my old bios. Please let me know the bios update for '07/10/1998-i440LX-8679-2A69JT19C-00'. Thanks for the support. --Ramki.
