device driver and BIOS

[rookie1010]

Hi
Is it true that all SCSI drives aren't controlled and managed by the BIOS?

Do all devices which are not controlled by the BIOS require a device driver and all devices controlled by the BIOS do not require a devicce driver?

umm.. wight want some more input on this, but i believe that ALL HARDWARE is managed by the bios.

software tells the hardware what to do. EVERYTHING REQUIRES A DEVICE DRIVER. It just depends if ur os supports it.


Hope I helped.
dont know what u mean about the scis though?

A microprocessor interperets machine code.
nvmnd w/ the machine code.
ok im not explaining this very well...

you could plug in some random circut or chip, bios NEEDS to see it in order for drivers to work IN the OS.
sry 4 the lousy explanation

but you could also have a piece of hardware that is supported by the bios, and is not supported by the OS.

more input?

is there a primer out there which illustrates the interaction between os , bios, hard ware and applications.

anything with illustrations would be great
