Yes, I saw this serial card from lspci output. But I haven't found how
to display detailed information for certain card. Sooner I'll give you
output from lspci -i.
With best regards

Well, assuming BIOS did initialize this card it may use different port
address. The one you see in setserial output is assigned by Linux
driver. I do not know how flexible it is, but I presume they may
Try lspci command in GRUB. Does it show your card at all? It also
displays some details of current card setup.
You may want to use "set pager=1" otherwise output will scroll too
If you see your card could you send screenshot of information GRUB
pulled out this adapter and inserted this pci serial adapter to the

Hi thank you for helping me!
Unfortunately I haven't got serial access to the grub after adding
piece of configuration:
###serial --speed=115200 --port=a880 --word=8 --parity=no --stop=1
serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1
May be I need some sleep time after inserting pci.mod. How I can do
You can pause with "sleep NN" but as I already wrote this is not
to work anyway - either GRUB needs code to initialize your PCI card
BIOS should do it. Try BIOS settings, in the past it was common to
something like "PnP OS" where "no" would cause BIOS to initialize all
available hardware and "yes" would leave it to operating system.

When I tried to manually type a "serial --speed=115200 --unit=0
--parity=no --stop=1" in the grub command line it complains that
port don't exist. I have played with unit and port attributes
without any luck.
Does "serial --port=a880 ..." work? If not, what exactly happens?
Note that you may need to load at least PCI bus driver (insmod
this to work.
I've tried to use it that way but it didn't find com port again.
I'll try to do insmod pci and write to you tomorrow.
help either. Card likely needs to be initialized first, and this
requires driver that knows how to do it. serial driver in GRUB
hardware is in working state already. Someone would need to
By the way is it possible to share documentation about some useful
modules in the grub? I havn't found any information using google.
