Hi, expert:
I have a question about IsaBus driver.

There is a isa bus driver in MdeModulePkg\Bus\Isa\IsaBusDxe.
But i find nobody use it anymore.

Based on current edk2-platform samples, they just use SioDxe driver plus Ps2Keyboard driver, not use IsaBus driver anymore.

So when to use IsaBus driver?

Thanks
