How to a card's BIOS via the system BIOS?

"The system BIOS has the ability to allow other BIOS chips that are located on adapters (such as the video card) to load software that is loaded in the card’s BIOS."


Taken from a computer training manual.


The way that I understand the sentence above is that you can update the video card's BIOS via the system board's BIOS. Does anyone else have a different opinion to my interpretation?


Or you can update the video card's BIOS or other card BIOS via firmware/BIOS updates  of system board.

Unless the system bios knows about the other items bios AND also has the updates for it which is highly unlikely then I believe the manual is in error except for veery limited systems.

I've never updated a computers bios that also upgraded the video card, raid card bios at the same time.  I have also never seen or heard of this happening.

debug c800:5  was the goto command to access the hard drives bios and set the cylinders,head,tracks and interleave and then format
The problem first was you had to set the interrupts to use on the card FIRST had to set the jumpers correctly (you only have 15 that are not virtualized

... and of the 15, most of them were permanently allocated to something else.  This was before shared IRQs and Windows support for same.  By the time a network card, CD controller and a Sound Blaster were in, most systems were already running out of IRQs.

Happy days ...

Software

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.
