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 the BIOS battery, but it's still there. What did get erased obviously is hw clock. This is what happens:
- I can leave lap top in January 1980 and it works
- I can correct system time, but boot will fail with "superblock mount time in future" from where I need to manually do fsck and continue boot
- I can correct system time and sync it with
hwclock -wbut than it will behave as 2) and it will reset BIOS time to 1.1.1980 00:00
- EDIT: I can set any time upto 1999??? I've tried with small time changes, then with bigger, then after many restarts I've figured out I can go from 1980 to 1999 directly, but If I go to 2000 from 1999 time is lost again.
So I need either a way to bypass a BIOS password (which after lot of googling seems impossible: http://www.techspot.com/vb/topic134536.html ),a way to persist a clock after year 2000, or a setup that will enable hw clock in nineties, system clock in present time and a normal boot.
