The Pavilion a6345f now has a PCI card with two serial ports. If the
SCSI adapter is not in the machine, kernel parameter
--console=ttyS0,115200 provided the boot sequence via the serial
crossover cable.

If the SCSI card is added, nothing comes from the kernel. Therefore
read
https://www.gnu.org/software/grub/manual/grub/html_node/Serial-terminal.html
and tried to configure output from GRUB.

grub> serial
error: serial port 'com0' isn't found.

The kernel recognizes the serial ports and GRUB doesn't? A
fundamental conflict between the SCSI card and other hardware?
Suggestions for a next step?

Thx,                             ... P.
