BIOS password and hardware clock problems
- by Slartibartfast
I have HP 6730b lap top. I've bought it used and installed (Gentoo) linux on it. BIOS is protected with password, and guy I bought it from said "I've tweaked BIOS from Windows program, it never asked me for password". I've tried to erase password by removing battery, but it's still there. What did get erased obviously is hw clock. This is what hapends:
a) I can leave lap top in January 1980 and it works
b) I can correct system time, but boot wil fail with "superblock mount time in future" from where I need to manually do fsck and continue boot
c) I can correct system time and sync it with hwclock -w but than it will behave as b) and it will reset BIOS time to 1.1.1980 00:00
So I need either a way to bypass a BIOS password (wich after lot of googling seems impossible),a way to persist a clock, or a setup that will enable hw clock in eighties, system clock in present time and normal boot.
