PXE sometimes fails to reboot
...ch method to use.
The reset via PCH register is just a write to IO space register 0xCF9h.
We recommend to perform a full reset via this register. In order to do
this, a value of 0x0eh needs to be written into this location.
I?m not the assembler guru but the following code should do the job:
Mov DX,0cf9h ; load port address
Mov al, 0e ; load reset value into al register
Out al,dx ;execute a full reset of the board
With kind regards,
