Grub 2 and PCI serial adapters

[Jan Krocker]

Hello,

i'm currently planing to migrate a PXE environment from grub 0.97 to
grub 1.99. In my current setup, i have several machines, using PCI or
PCIe cards to provide a serial I/O. Those Ports are recognised as Com 0
or Com 1 by grub 0.97. Grub 1.99 doesn't recognise all of the cards we
are using. Especially non of the PCIe cards is working.

How does the recognition work? Where is this part documented? Do you
have a list of known good devices?




Kind regards,

Jan Krocker
