back when, people sold
BIOS upgrade cards that provided a BIOS extension so that you could use hard
drives not originally designed for the computer. What were these boards

An ability to add an extra ROM chip is handy.
You COULD edit your existing BIOS, and burn a new ROM.
In the 5150, there was room for 48K of ROMs, with 40K being used. There
were a few aftermarket add-on ROMs.
An extra board with ROM(s) would be handy.
But, if you can manage to boot an OS with the existing hardware, it is
trivial to write a TSR that can augment or supplant part or all of the
ROM(s)
