Hi all,
I'm looking to run some firmware under QEMU.
But currently it hangs at early initialization.
It uses timer (i8254) operations to calibrate some internal variables.
The main drawback is that it uses output 0x80 to port 0x61 to clear
IRQ0 state.
QEMU (0.14.5) have only PC Speaker attached to this port, so it
ignores any writes to higher bits...
Are there any options to correctly emulate PS/2 compatibility?
wbr,
Dmitry.
