In a previous email message
http://www.clustermatic.org/pipermail/linuxbios/2003-November/005891.html
I wrote
In V1 the file to modify is src/superio/via/vt1211/setup_serial.inc
That code sets up ttyS0 which is the VT1211's logical device 2. You
want to add some similiar code for logical device 3 to get ttyS1 working.
Assuming you want it to be at 2f8 you'd merge in these lines:
OUTPNPADDR($7)
OUTPNPDATA($3)
/* set the enable in reg. 0x30 */
OUTPNPADDR($0x30)
OUTPNPDATA($0x1)
/* Serial Port 2 Base Address (BEh) */
OUTPNPADDR($0x60)
OUTPNPDATA($0xbe)
/* Serial Port 2 IRQ (03h) */
OUTPNPADDR($0x70)
OUTPNPDATA($0x3)
/* Serial Port 2 Control */
OUTPNPADDR($0xf0)
OUTPNPDATA($0x2)
...then do the turn off pnp
/* turn off PnP */
OUTPNPADDR($0xaa)
...then duplicate the serial setup except the address goes from 3f8 -> 2f8
There is a piece missing. I had to enable the second serial port on the VT1211
and although linux recognized it, there was no serial activity on the lines.
These lines need to be added during the vt1211 configuration:
/* Allow serial port 2 (ldn 3) pins to come out */
OUTPNPADDR($0x27)
OUTPNPDATA($00)
This has to be before the $0xaa write to turn off configuration mode.
The default value on powerup for this register on the vt1211 is 0xff.
There are multi purpose pins on the chip and this connects them to the second
serial port.

Yeah, Slasdot obviously is not intended to be used as a message forum for
lingering discussion.
Ron has a working image that was used for what I gather is a similar
mainboard. Output from lspci would also be helpful so that we can make
sure the hardware on your board is the same as the hardware on ours
(Whatever came in the ITuner Minibox M-100's).
P.S. I cc'd this e-mail to the mailing list (
http://www.clustermatic.org/pipermail/linuxbios/2003-December/ ) since
the EPIA is a rather popular platform and others might be able to offer
help in this matter.
Etherboot can boot a kernel over a LAN, and IDE disk, floppy, and probably
some others too. Are you using an ethernet bridge like a Linksys WET11
or an add-in PCI or USB wireless device?

hi, I'm new for LinuxBIOS. I have problem about my
mainboard(VIA-EPIA) Now I'm use LinuxBIOS but I want
to customized it to chang payload from etherboot with
my program about serial port(now this mainboard use
serial console) how can I'change it(my program use
assembly). Thank you for answer

Hi,
I like to have my linuxbios, linux OS, filesystem in the same
diskonchip millennium. If I have to use diskonchip millennium with
linuxbios, to which physical address should the DOCM should be mapped in
hardware ? Is any driver should be loaded before the OS gets loaded? I have
mapped in hardware 0xFFFFFFFF-0xFF800000. Is this correct? Does any
remapping is to be done in hardware afer this?
Which file system should I use?

Hi,
This is my first posting to this list. Before posting this mail I
searched for any support of net 4501 soekris box.
Is net 4501 soekris box is supported by linuxbios?
Thanks in advance,
Best Regards,
Ravi
