Etherboot ...
by Denis Pilon 14 Apr '03

14 Apr '03

OK. Got an image built using etherboot-5.0.8 I think it works, but the e1000 driver is to old so it can't network boot. Using the etherboot-5.1.3, the elf image is to big. How do I shrink the romimage to fit 524288 ? Denis

RE: Still not having success with SM P4DPE
by Atherton, Stephen 14 Apr '03

Linuxbios.strip is 49152 bytes, and eepro100.elf is 22368. So that gives a total of 71520...larger than 65536. So one of them is too big. Any idea which? -Steve -----Original Message----- From: steven james To: Atherton, Stephen Cc: 'linuxbios(a)clustermatic.org' Sent: 4/11/03 9:25 AM Subject: Re: Still not having success with SM P4DPE Greetings, It looks like the fallback image is being built wrong. This can be hacked together manually. linuxbios.strip should be the actual LinuxBIOS code. The objective is to assemble a 64K (exactly) block containing: 1. etherboot 2. null padding (can be generated with dd if=/dev/zero) 3. linuxbios.strip. I just use calctool to figure out how much padding to use and cat eepro100.elf pad linuxbios.strip >fallback.bin the 64K fallback.bin can then be appended to the primary image to get the full rom image. That's a little ugly, but it should get the job done. Just as a final verification, in linuxbios.map, ZKERNEL_START for the fallback image should be 0xffff0000. That is whjere it will look for the fallback etherboot. Also, it will ljmp to ZKERNEL_START-8 to transfer control to the primary image. I'm slowly trying to disentangle that on the boards I have. Unfortunatly, I don't have a P4DPE. G'day, sjames On Fri, 11 Apr 2003, Atherton, Stephen wrote: > Ron and James, thanks for clueing me in on the fallback image stuff.

Got linuxbios coming up on a x5dpe-g2, but it will not grab an IP. It just sits there looking for dhcp server. Looking at the dhcp logs, the etherboot never sends the DHCPACK. What do I do ?

Hi, I am using geode sc1200 chip. I have to do some initialization to my sc1200 and then load my linux OS from hard disk to SDRAM. Can linux bios satisfy all these? What else can linux bios do? Catch all the cricket action. Download Yahoo! Score tracker

Kernel exec functions and new problems (long)
by Gregg C Levine 13 Apr '03

13 Apr '03

Hello again from Gregg C Levine Well, switching to the latest of Eric's kernel exec tool, has made a difference. Instead of getting those annoying "oops" messages, I am now getting something far more meaningful. Although it means nothing to me, (or it should and I don't know what to look for), it does indicate, that your assertions Andrew are leaning towards being correct. Here's the message: Script started on Sun Apr 13 11:36:57 2003 root@who4:/usr/src/LoBos/work# ./kexec kernel.elf kexec_load failed: Function not implemented entry = (nil) nr_segments = 4 segment[0].buf = 0x80a8ee8 segment[0].bufsz = 158 segment[0].mem = (nil) segment[0].memsz = 158 segment[1].buf = 0x80a3888 segment[1].bufsz = 55e0 segment[1].mem = 0x10000 segment[1].memsz = 55e0 segment[2].buf = 0x80a8e70 segment[2].bufsz = 0 segment[2].mem = 0x91000 segment[2].memsz = 0 segment[3].buf = 0x40001008 segment[3].bufsz = b48dc segment[3].mem = 0x100000 segment[3].memsz = 700000 root@who4:/usr/src/LoBos/work# exit Script done on Sun Apr 13 11:37:15 2003 At a guess, I'd say, it is telling me that the function was not correctly implemented on this kernel, which is 2.4.20. So, this does backup that notion that I should grab a copy of the raw 2.4.19 sources. I'll do that later today, and try again. However while building the version 1.8 tool, I received a number of warnings, nothing severe just simple warnings. I'll post them after the signature block. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

Kexec and kernel oops
by Gregg C Levine 13 Apr '03

13 Apr '03

Hello from Gregg C Levine Here is a strange bit of events, I just finished recompiling my Linux box's 2.4.20 kernel, after applying the kernel patch supplied by Andrew Ip. The patch applied with the usual amount of fuss. No problems surfaced during the build process. Nor with anything else. Except for the kernel exec tool. Since I wasn't sure if Andrew had back ported the ones from the 2.5 series to the 2.4.20, and 2.4.19 ones, I chose the original command line one, and built that. I chose the original 2..2.19 kernel as the one to exec. Original that is, because this version of Slackware is 8.0, and that's the version that works for it to install correctly here. Also the tools that I have used, are from that release version. Each of the different versions of the make elf Image tools from 1.6, to 2.0 that I tried,. gave me an oops message, and caused the program to abort with a segmentation fault. Here's a cut and paste of my oops message from the dmesg log: Script started on Sun Apr 13 02:36:24 2003 root@who4:/usr/src/LoBos/work# kernel BUG at slab.c:1437! invalid operand: 0000 CPU: 0 EIP: 0010:[<c012b79a>] Not tainted EFLAGS: 00010016 eax: 5a2cf071 ebx: c10b6020 ecx: c105f2c0 edx: 6444c888 esi: c10b6f18 edi: 0002df48 ebp: c0eafd40 esp: c0eafd20 ds: 0018 es: 0018 ss: 0018 Process kexec (pid: 131, stackpage=c0eaf000) Stack: 04000000 00010740 c10b6f9c c0eafd9c 00000080 c10b6f1c 00000282 c105f2c0 c0eafd9c c014f00e c10b6f1c 00000080 c0eafdd0 c0eafe9c 00000000 00010740 00000004 c10b6f1c 464c457f 00010101 00000000 00000000 00030002 00000001 Call Trace: [<c014f00e>] [<c014b903>] [<c012041d>] [<c01bdfbd>] [<c0186c38>] [<c017f32f>] [<c017b02e>] [<c017f14c>] [<c0132e27>] [<c0108a73>] Code: 0f 0b 9d 05 80 89 22 c0 8b 7d fc b8 71 f0 2c 5a 89 f2 03 57 kernel BUG at slab.c:1437!

This time I tripped the kernel exec on a remote console, and watched the main one. The main one displayed the oops, and the remote console gave a segmentation fault as its error. So? Anybody out there, recognize the fault? I personally think it has to do with my choice of kernel exec command line tools. Also, versions 2.1, and 2.2. and 2.3 of the make elf Image too, didn't work here. I'll grab that as a script file for the latest release, and present it later. Andrew did you indeed back port the 2.5 series of kernel exec patch functions to the 2..4.19, and 2.4.20, as I have now decided? ------------------- P.S. If that's the case, then don't worry about it any. It is my fault for choosing the wrong tool to use first. --------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

How does the OS boot OS
by Shubhangi Jadhav 13 Apr '03

Hi, I'm trying to understand the working of LinuxBIOS. The FAQ says that it uses a real OS is used to load the OS. Can someone elaborate on this ? Is it that the kernel image which you burn along with linuxbios on the BIOS Flash ROM is copied to RAM, performs the hardware initialization and then it invokes the other OS which in my case would be linux? How is the other OS invoked ? Thanks, Shubhangi
