intel firmware hub parts

has anyone found a distributor for these parts? this is really amazing, but nobody I have talked to sells them. They get them via hook and crook from intel, but actually buy them? never happens. ron

It doesn't, and this is an important point that I am trying to clarify with their engineers who claim that it will work from 3v3. As I said, if anyone can recommend something better I would love to hear about it.

Re: Linuxbios + Etherboot + tagged Kernel Image
by Yap Ee Huey 06 May '03

06 May '03

Yes, I am going to use etherboot to load kernel image, but I don't know how to link those files. Bendany told me : "etherboot will init the harddisk, and get the linux kernel from the first partition of your harddisk. so you just put the kernel into your harddisk's first partition and the kernel name must be "kernel". filesystem can be ext2. " But I have multiple partitions on my harddisk, Linux is not on /dev/hda1 , is there any other solutions ? Thanks. >From: ron minnich <rminnich(a)lanl.gov> >To: Yap Ee Huey <yapeehuey(a)hotmail.com> >CC: linuxbios(a)clustermatic.org, <etherboot-users(a)lists.sourceforge.net> >Subject: Re: Linuxbios + Etherboot + tagged Kernel Image >Date: Thu, 24 Apr 2003 08:42:08 -0600 (MDT) > > >one quick question: are you using etherboot to load the kernel image? > >ro > _________________________________________________________________ Using a handphone prepaid card?

Delay in copying Linuxbios to ram
by Shubhangi Jadhav 06 May '03

06 May '03

Hi, While trying to boot using linuxbios , I get a message " Copying LinuxBIOS to ram " and then the system pauses for 3-4 secs, before printing the next message - "Jumping to Linuxbios" Could someone tell me what causes this delay, does the process of uncompressing and copying linuxbios to RAM take this long? Any suggestions on how to reduce this delay? Here's the log of the debug messages. ***************log********************************* LinuxBIOS-1.0.0 Thu Apr 24 06:42:06 IST 2003 starting...

Hammer Documentation is now Available at AMD's website
by ebiederman＠lnxi.com 06 May '03

06 May '03

So far I have just skimmed the Documentation but it appears that AMD has now publicly published everything needed to do Hammer LinuxBIOS port. No great surprise but it is nice to actually see it ! Yeah! The chaos with the Dual Athlons has finally paid off :) Eric

low compression of kernel
by Felix Kloeckner 01 May '03

01 May '03

hello, just a simple question: what's the reason for using only a compression level of 3 instead of default or even maximum? 9 works fine for me and give me some additional space for the kernel "makerule linux.bin.gz: linux.bin ;gzip -f -3 linux.bin" in "src/arch/i386/config/make.base", line 39 felix

Re: ADLO is GO
by Richard Smith 30 Apr '03

30 Apr '03

Ok. that fixed it.. ADLO is booting for me. For the list: I had to enable read and write in the shadow memory. I don't think you had to but I enabled the full range from 0c0000 to 0ffffff Adam: I added a macro that does a PCI config space write. Saves you from haveing to do all the calulations. Would you like a diff? It doesn't appear however that my video bios is getting called. I rememember seeing somewhere that I have to enable that? -- Richard A. Smith rsmith(a)bitworks.com

ADLO Video is up

Adam Sulmicki wrote: > can you just diasable/remove debug patch and see what happen? i actually > never used that patch. Thats what it was. I commented out SERIAL_DEBUG and now I have text on my monitor. Dude this is COOL. Ok... Now. This board is a multi-head board so there are actually 2 69000 on the PCI bus. I also need to init the second chip as well. The way we did this under General software was to activate chip 2. run bios. Deactivate chip 2. Activate chip 1 and then re run the bios. Would I have to do such a thing for BOCHS as well or is there a better way. -- Richard A. Smith rsmith(a)bitworks.com

ADLO no go
by Richard Smith 30 Apr '03

30 Apr '03

I'm trying to get ADLO up but once it jumps to adlo nothing happens. I've applied the serial-debug patch to ADLO but still no results. Are there any specific memory region options that I need to have enabled /disabled? Heres the snipit from my serial output. Welcome to elfboot, the open sourced starter. January 2002, Eric Biederman.
