LinuxBIOS + Etherboot Problems
by Jeff Stevens 15 Sep '04

15 Sep '04

I am trying to load a kernel over Etherboot, and am having some problems doing so. I am using etherboot version 5.2.2, and mkelfImage 2.5 released 24 April 2003. Here is the output I get: --> Welcome to elfboot, the open sourced starter. January 2002, Eric Biederman. Version 1.3 Loading Etherboot version: 5.2.2 ROM segment 0x2e81 length 0x7938 reloc 0x00020000 CPU 1664 Mhz Etherboot 5.2.2 (GPL) http://etherboot.org Tagged ELF for [3C90X] get_memsizes | linuxbios Relocating _text from: [000244e0,00034330) to [efef01b0,eff00000) Probing pci nic...

I have booted this kernel on this machine fine before (when it was burned into flash and booted directly from LinuxBIOS). Do I need to change anything in the targets Config.lb when I run etherboot, or should it be the same as when I burn the kernel into flash? I am also able to boot the kernel over Etherboot fine on another one of my machines booting etherboot from a floppy. On the machine in question, Etherboot is the payload of LinuxBIOS. Please help!

How can I had the broadcom NIC ? When I comment out this in Config.lb (mainboard)? dir /drivers/broadcom/tg3_ipmi the buildtarget utility says it is not in the Sourcetree. When I change this line to be: dir /drivers/broadcom/tg3 (existing dir in the Sourcetree) there is a make error. I tried it with gcc-3.3.1 and gcc-3.3.2 I have binutils 2.15. Did you ever succeed to build an image supporting broadcom NIC ?

epia m vga + memcpy update
by Trellix78＠aol.com 14 Sep '04

14 Sep '04

hate to be clogging up the list but memcpy works!! It looks like the VT8622/8623/8635 all have the same way of dealing with this shadow copy stuff. After losing a couple of hours sleep, I've hit another snag here (partial log): ==================================== setting pci slot setting vt8235 slot Assigning IRQ 5 to 0:11.1 Readback = 5 Assigning IRQ 12 to 0:11.5 Readback = 12 INSTALL REAL-MODE IDT DO THE VGA BIOS found VGA: vid=1106, did=3122 Setting up VGA, VGABIOS_START: 0xfffc0000 write_protect_vgabios Looks like VGA_ROM is good: 0x55 0xaa VGA copy looks good bus/devfn = 0x100 biosint: # 0x15, eax 0x5f00 ebx 0x100 ecx 0x100 edx 0x12 biosint: ebp 0x138dc esp 0xff2 edi 0xf934 esi 0x141f8 biosint: ip 0x637f cs 0xc000 flags 0x46 calling handleint21() done with handleint21() returning from biosint()...ret=-1 biosint: # 0x1a, eax 0xb108 ebx 0x0 ecx 0x0 edx 0x3d5 biosint: ebp 0x138dc esp 0xfcc edi 0xf6 esi 0x155eb biosint: ip 0x40da cs 0xc000 flags 0x46 calling pcibios() 0xb108: bus 0 devfn 0x0 reg 0xf6 val 0x3 done with pcibios() returning from biosint()...ret=0 ================================================= I've tried to put some debugging outputs but the system just grinds to a halt after the second call to biosint(). It's now my belief that directly manipulating the registers on the Apollo CLE266 northbridge might yield better results for the epia M. VIA doesn't seem inclined to give out the datasheets or source code, as the posts on viaarena indicate. I wonder if looking at the linux driver patches for kernel 2.4 and greater might offer some clues. Any help would be greatly appreciated!

I try to build bios for tyan s2850 with broadcom NIC. This is the ERROR I got: [broadcom_nic.c] /tmp/ccXAyjD1.s: Assembler messages: /tmp/ccXAyjD1.s:39: Warning: setting incorrect section attributes for .rodata.pci_driver /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.3.1/../../../../i686-pc-linux -gnu/bin/ld: warning: cannot find entry symbol _start; defaulting to 08048074 /tmp/ccavzIGX.o(.text+0xb): In function `broadcom_nic_init': : undefined reference to `pci_read_config16' /tmp/ccavzIGX.o(.text+0x1a): In function `broadcom_nic_init': : undefined reference to `pci_write_config16' /tmp/ccavzIGX.o(.text+0x26): In function `broadcom_nic_init': : undefined reference to `do_printk' /tmp/ccavzIGX.o(.data+0x0): undefined reference to `pci_dev_read_resources' /tmp/ccavzIGX.o(.data+0x4): undefined reference to `pci_dev_set_resources' /tmp/ccavzIGX.o(.data+0x8): undefined reference to `pci_dev_enable_resources' collect2: ld returned 1 exit status What is the problem ?

How open is scitech to a restructure of their work? We could simplify things a lot.

Good luck :-) I have plenty of things on my todo list, too. I will create a repository within the next 1-2 weeks, so until after 9.2 we can start with major spring/winter cleanup ;) Stefan

Oh its far worse than that. They actually have special extensions that the OEM has to support so that they can do special stuff for TV out or LCD panel type detection. And of course this is all Mfg specific and only the info only acessable under NDA. > I would prefer to do this stuff myself as Jon is mostly working on > top of my old code.

So you want to seed the repository with the stuff from X.org and let everyone else re-implemnt thier stuff on top of that and then feedback what changes they had to make?
