Bios passwords are stored on the CMOS, not the Rom itself, so no, it 
doesn't have to be.
On the other side, if you can flash your ROM, you have iopl(3) hence 
root privileges or
at least enougth privileges to get those passwors back (1). So that's 
really no bid deal.

the main source of postings on this list.
