by Diarmid Vaughan 13 Mar '03

13 Mar '03

I am new to linux and to linuxBIOS. I am interested in linuxBIOS. Can someone tell me how to start with my make of Motherboard. My motherboard is as follows: Jetway 694TAS with: VIA 694T/686B chipset Socket 370 Intel celeron (i have windows xp and mandrake linux 8.1 on it) The link about my board is: http://www.jetway.com.tw/evisn/product/socket370/694tas/694tas.htm i need to know what i need to do in order to start and where to go from there. Thanks Vaughan Diarmid

Missing file from download page on website
by Gregg C Levine 12 Mar '03

12 Mar '03

Hello from Gregg C Levine One of the files isn't available from the download page for the Linux BIOS website. Which is http://www.linuxbios.org/developer/download/index.html The file name, is tboot.c. It's my guess, is that particular file wasn't brought over, when the new site was constructed. It's not important. But it is an interesting bit of code. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

I don't have ICE (Could you recommend one ?) . Therefore I printed post code at several point of bochs code. And I think it stop during VGABIOS execution because it works before option rom scan procedure. I think EPIA bios do something on northbridge settings which VGABIOS require. How do you think? I found some VGA related registers on northbridge such as 0xfb register which have 'VGA Enable' disable bit. However When I enable it, strangely etherboot doesn't works and system restarted. (My boot configuration is linuxbios -> etherboot -> ADLO payload ) Hmm.. > > -- > Adam Sulmicki > http://www.eax.com The Supreme Headquarters of the 32 bit registers >

Booting VxWorks from LinuxBios - success
by Felix Radensky 12 Mar '03

12 Mar '03

Hi, I've finally managed to boot VxWorks from linuxbios using old (non-elfboot) method. This required placing linuxbios itself to other memory location (0xC0000 instead of 0x4000) and reducing it's heap size to 64K, so that data, bss, heap and stack could be placed between 0xC0000 and 0xF0000. To make these areas mapped as DRAM and not PCI, I had to initalize PAM registers differently. After I've managed to relocate linuxbios code, booting vxworks was easy. The VxWorks bootloader is uncompressed to 0x8000 and jump is performed to 0x8010 (protected mode entry point). If anyone is interested in more details, I'll be glad to provide them. I'd like to specially thank Peter Fox and Cristopher Stutts for their help. Felix.

I mean I did as Slumicki suggested. First I booted with original EPIA bios. Then changed image with linuxbios and did soft-reset while power is on. This can be done because I have rom-emulator. > -----Original Message----- > From: Andrew Ip [mailto:aip@cwlinux.com] > Sent: Wednesday, March 12, 2003 1:22 PM > To: hcyun(a)etri.re.kr > Cc: adam(a)cfar.umd.edu; linuxbios(a)clustermatic.org > Subject: Re: ADLO for EPIA > > > > I tried but no success. > In the current cvs tree, vga is not enabled.

Both keyboard and mouse are plugged and of cause I can boot linux with LinuxBIOS. Is there any board depedent part other than shadow memory control? For now, I just want to see screen output from VGABIOS or BOCHS BIOS.

I tested ADLO on EPIA but it failed on the first try. I grapped vgabios using your Makefile target and modified loader.s to enable shadow ram control registers of EPIA. However, it hang around post code 0x96 and nothing is shown on the CRT. Do you have any idea what 0x96 post code means. Is it a bochs post code or vgabios postcode? > -----Original Message----- > From: Adam Sulmicki [mailto:adam@cfar.umd.edu] > Sent: Tuesday, March 11, 2003 4:13 AM > To: hcyun(a)etri.re.kr > Cc: linuxbios(a)clustermatic.org > Subject: Re: ADLO for EPIA > > > > I'm trying to bring up VGA on EPIA board. > > >From the list, EPIA board is supported and I've tested > with Angrew's image. > > However, due to full support of VGA is necessary, I'm > trying to figure out > > ADLO to run binary only > > VGABIOS rom image. > > Can I acomplish this with ADLO?.

ADLO for EPIA

Hello, I'm trying to bring up VGA on EPIA board. >From the list, EPIA board is supported and I've tested with Angrew's image. However, due to full support of VGA is necessary, I'm trying to figure out ADLO to run binary only VGABIOS rom image. Can I acomplish this with ADLO?. If yes, how much extra work will be needed you think? Thanks, - HeeChul Yun, Embedded S/W Team at ETRI phone: +82-42-860-1673
