As BigV described, BIOS is a program that exists only in the motherboard. BIOS then loads other programs from the hard drive, from the CD-Rom, or from a memory stick.
Programs it can load are comprehensive hardware diagnostic (from hard drive, CD-Rom, or from what was downloaded from the Sony web site), Console Recovery program (from the Microsoft CD-Rom), PTDD (from that CD-Rom), disk drive manufacturer's diagnostic (downloaded from the disk drive web site), DOS, or Windows (from hard drive or Microsoft CD-Rom). You choose what BIOS will load and execute by what you put into the CD-Rom or memory stick. Or by pressing F2 to select what you want to execute from that menu (same menu that jinx choose to boot with or without network support).
Fixmbr is only one of many repair programs available on the Recovery Console (one a Microsoft and Sony provided CD-Rom). It will fix software on the disk drive.
However if a diagnostic does not first confirm disk drive hardware is OK, then fixmbr might cause permanent data damage. That is why more responsible computer manufacturers (ie Dell, HP) provide comprehensisve hardware diagnostics for free. And why everyone knows Gateway and E-machines are crap.
Provided are numerous options. Same thing is posted by so many with different words. Every post at layman's level.
All solutions load and execute only when the BIOS does so. You select what the BIOS loads either by installing the appropriate CD-Rom (or memory stick) or by using that F2 key to select what to load.
Everything you have posted implies the motherboard CPU is talking to the disk drive's CPU.
