EPIA-M + second serial port enabler
by Dave Ashley 15 Dec '03

15 Dec '03

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. -Dave

Re: VIA EPIA mini-ITX mainboards

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).

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? _________________________________________________________________ Download cool KHNH ringtones.

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?
