[ANNOUNCE] mkelfImage-2.2
by ebiederman＠lnxi.com 06 Feb '03

06 Feb '03

mkelfImage 2.2 is a bug fix release, available at: ftp://ftp.lnxi.com/pub/src/mkelfImage/mkelfImage-2.2.tar.gz rpm -bb mkelfImage-2.2.tar.gz builds a binary rpm. In some cases when working with the latest versions of etherboot the i386 stub code would get confused and use the wrong table address. The result is that the kernel image would just hang. That problem is now fixed. Eric

more on objcopy

ok, I think objcoyp is doing the right thing. Whew! Here are the sections: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .rom PROGBITS ffff4000 001000 002400 00 AX 0 0 8 [ 2] .payload PROGBITS ffff6400 003400 0049b3 00 WA 0 0 1 [ 3] .reset PROGBITS fffffff0 007ff0 000010 00 A 0 0 1 [ 4] .id PROGBITS ffffffd3 007fd3 00001d 00 A 0 0 1 [ 5] .text PROGBITS fffffff0 007ff0 000000 00 AX 0 0 4 [ 6] .data PROGBITS fffffff0 007ff0 000000 00 WA 0 0 4 [ 7] .bss NOBITS fffffff0 008ff0 000000 00 WA 0 0 4 [ 8] .shstrtab STRTAB 00000000 008ff0 000045 00 0 0 1 [ 9] .symtab SYMTAB 00000000 0091f0 0010e0 10 10 bf 4 [10] .strtab STRTAB 00000000 00a2d0 0010f8 00 0 0 1 The .rom starts at 0xffff4000, which gives you a 49152-byte section. I think the .ldscript is giving a fixed-size linuxbios without regard to how big it actually is, which means tuning via things like max log message etc. is no longer a real option. It also means my etherboot, which is 17K, no longer fits together with linuxbios into 64K. OK, back to the drawing board :-) ron

objcopy -O binary behaviour
by Ronald G. Minnich 05 Feb '03

05 Feb '03

this is interesting and I just hit it. objcopy -O binary appears to be rounding the output to the page size. So, in some cases, your binary will GROW, not shrink, when you do this: objcopy -O binary linuxbios linuxbios.strip So for example I have a 46024-byte linuxbios, which grows to 49152 bytes AFTER it is stripped. most inconvenient. I'm trying to figure out what makes this happen. It's not a great thing, however. Even older objcopy's do it, e.g. 2.13.90.2 does it, but so does 2.11.90.0.8 I love BFD but somedays I think it wants to kill me. ron

X and linuxbios
by Alessio Sangalli 05 Feb '03

05 Feb '03

Are there known problems with XFree86 and linuxbios? I use a pcchips motherboard with linuxbios from cwlinux.com, and when I start Xfree86 it says 'v_bios not found' and refuses to start. Any hints? -- How to build a lirc receiver http://www.manoweb.com/alesan/lirc

Maybe it's offtopic (sorry for that), but i don't know other list to ask this question. How many time can you burn a DoC? Thanx Paulo Richards

440BX
by Jeffrey Knight 04 Feb '03

04 Feb '03

Some questions from a newbie .... I have an Intel motherboard with PII and a MP440BX PCI chipset. I know that I can do a software upgrade my BIOS using the iflash.exe util from intel. I'm trying to figure out if I can make linuxBios work. The motherboard is listed as supported. There's no docs under freebios\freebios\HOWTO\ for 440BX; is building for the 440BX analogous to building for the L440GX? (I see the l440bx-test12.config file in the util directory.) Thinking that steps for 440BX might be similar to those for L440GX, I followed the HOWTO for L440GX and grabbed a 2.4.0-test12 kernel. But according to the HOWTO for L440GX, I need to patch the kernel with: freebios\src\kernel_patches\linux-2.4.0-test12-l440gx.patch which doesn't exist. Yet according to the HOWTO at \freebios\src\kernel_patches\HOWTO: "For 440BX users: irq_route.diff is Tyson Sawyer's patch to properly handle LINUXBIOS kernels. It has been tested on 2.4.0-test6 kernels." ... so should I use a 2.4.0-test6 instead of a 2.4.0-test12 kernel, and patch it with irq_route.diff for a 440BX? Thanks for your help!

mainboard sub-type support
by Ronald G. Minnich 04 Feb '03

04 Feb '03

We have a mainboard called the p4dpe-g2. It seems to be almost identical to the p4dpe. I was faced with several options: - have a directory named p4dpe and a directory p4dpe-g2, with almost identical files - Have a directory for the p4dpe, with #ifdef G2 in many files - an interesting trick that works: have a directory p4dpe, and a directory p4dpe/g2 Populate p4dpe/g2 with the files: cmos.layout, Config, mainboard.c, irq_tables.c, and mptable.c in other words, the files that will change with mainboard revs anyway This last option works. The only change to the config file to build a -g2 motherboard is to change the line: mainboard supermicro/p4dpe to mainboard supermicro/p4dpe/g2 Now this is kind of interesting. For a vendor like supermicro that spins lots of boards that are very similar, we can take this further: have supermicro/mainboard/p4d/pr for the p4dpr and supermicro/mainboard/p4d/pe for the p4dpe. These are similar boards, lots of shared code, and this structure shows that. Comments? is this good, bad, or indifferent? ron

kernel config for linuxbios
by Alessio Sangalli 03 Feb '03

03 Feb '03

Hi. I've examined kernel patches freebios/src/kernel_patches and the patched kernel 2.4.20 avaiable at cwlinux.com. I've noticed that there is a way to configure linuxbios support and linuxbios power management if I apply linux-2.4.19-sis.patch to a vanilla 2.4.19. On the other hand, cwlinux's kernel has some great patches (like preemptive kernel) and a 2.4.20 version, but no "linuxbios support". Which one should I use? perhaps it's only a matter to apply linux-2.4.19-sis.patch to a 2.4.20 kernel (some work is needed) to have the best kernel for linuxbios. bye thank you as

Via EPIA
by russell＠abc9986.demon.co.uk 03 Feb '03

03 Feb '03

I've spent tha last couple of days working on an EPIA motherboard. I currently have a build that will warm boot provided the initial boot was with the original bios. On a cold boot the kernel crashed at diffrent stages. I see some errors relating to the ram setup, and Linuxbios is only finding 64Meg I have 256meg! Could someone please tell me what i need to do to get the RAM configured correctly. Thanks Russell

acpi shutdown + cool logo + nvram
by Alessio Sangalli 02 Feb '03

02 Feb '03

Is it possible to shutdown the pc with an actual powerdown with linuxbios on a pcchips810? I've flashed linuxbios from cwlinux.com (I boot from an IDE hard disk) and I've enabled acpi on the kernel. However the command 'halt' didn't shutdown the machine. I had to keep pressed the power switch few seconds for it to turn off. Is it allowed to insert a custom logo, instead of the tux one which is displayed on the first seconds of the boot? Which file is the definition of the logo, and is it the same format of the kernel? Is it possible to set the nvram values to have the pc being powered up at a specific time using nvram-wakeup or similar programs? Sorry for the massive amount of questions but linuxbios is *very* cool! bye as
