I am trying to get Kali to run on a PC with 6 COM Ports. It is seeing four of them but the 5th and 6th appear in DMESG as disabled. I have tried using setserial but it never creates ttyS04 and ttyS05.

I have tried various grub boot modifications but most things I have found want you to recompile the kernel which I am not sure how to do.

The serial ports are onboard and it is an Intel Serial Card. In lspci is says that it is an 8 port card and is using IRQ19. In the Bios and in logs each port has it's own IRQ and hardware number none of which is IRQ19.

Any suggestions?

Thanks in advance.
