Thanks a lot! I will try it! :) Lawrence -----Original Message----- From: Eric W. Biederman [mailto:ebiederman@lnxi.com] Sent: 2003?1?10? 15:38 To: LinuxBIOS Cc: Lawrence LL.

The difference is mknbi/mkelf that come standard with etherboot when the process the linux kernel start the kernel in 16bit mode and run it's BIOS code, mkelfImage simulates the effect of the 16bit BIOS code by reading LinuxBIOS tables or making the needed BIOS calls itself, and then it enters Linux at it's unofficial 32bit entry point. mkelfImage can take either a bzImage or a vmlinux.

WANTED: LinuxBIOS capable rack mount servers
by Jeremy Jackson 10 Jan '03

10 Jan '03

Where can I buy 6 rackmount servers 1GHz+ with LinuxBIOS potential? They are for production website, so must be *stable*, if none available with LinuxBIOS then it's back to the old (BIOS) grind. It's just that I have the opportunity to build this from scratch, and I'd like to go LinuxBIOS if possible. 2 need 3 ethernet + DOC roof fs + no disk - router/apache load bal 2 need 2 ethernet + load kernel over net and do NFS root ) webservers 2 need at least 2 disks hotswap SCSI (small database) It would be wonderful to have all 6 the same chassis/motherboard, with the difference being cards/disk plugged in. Also nice would be ability to fall back to vendor bios in case of trouble in testing phase. Delivery must be in 2 weeks at most. Thanks, Jeremy

RE: about E7501
by Terry B. Chen 10 Jan '03

10 Jan '03

Sorry, I do not mean I have finished the porting, I just read the raminit.inc about E7500, now I am reading E7501 and E7500 Intel bios specification. I try to find the difference between two chipsets. But I am raw in ram initialization. The part is so complex. I want to get help from you.

Hey before you do that could you give me a copy of your E7501 port? Sorry I could not resist. I doubt the differences are especially large but I have not gone through the documents and looked closely yet. Eric

about E7501
by Terry B. Chen 10 Jan '03

10 Jan '03

Is anyone interested in E7501? What is the difference between FSB 533 and 400 in Northbridge? I have a thought to port E7501 to E7500. Someone give me some suggestions! Thank you ! Best Regards Terry Chen

Boot from etherboot - blocked by INT 10
by Lawrence LL. Dai 10 Jan '03

10 Jan '03

Hi, When I try Linux bios to boot from Ethernet, I find it will be blocked by an instruction of INT 10. The kernel downloaded from TFTP server has the INT 10 instruction, while INT 10 has not been realized in Linux bios. So it is stopped. How can I resolve the problem? Thanks, Lawrence

Intel A, B, etc. nomenclature (fwd)
by Ronald G. Minnich 09 Jan '03

09 Jan '03

interesting note on intel speeds that I never noticed. ron ---------- Forwarded message ---------- Date: Thu, 09 Jan 2003 08:45:26 -0500 From: JOHN DEGOOD <jdegood(a)sarnoff.com> To: rminnich(a)lanl.gov Subject: Intel A, B, etc. nomenclature When Intel does a die turn the speed range of the new processor sometimes overlaps with the earlier die, so to distinguish the chips they use "2.0 GHz", "2.0A GHz", "2.0B GHz", etc. The functionality often is significantly different, e.g. the P4 "1.8 GHz" has 256K cache, while the P4 "1.8A GHz" has 512K cache, so the "1.8A" benchmarks much better.

Does anyone knows the proper inicialization sequence for SIS 630 VGA graphics, so I can use it with linuxbios? andre http://usuarios.uninet.com.br/~aod ----------------------------------------------

are there problems with this email? - what is a disc on chip? - beginner's question
by Alessio Sangalli 08 Jan '03

08 Jan '03

Hi, this is not the first time I write but in the past months I was too busy and I had no time to build a nice linuxbios-box! However now I'm going to buy a pchips motheboard so I can start to experiment. I've read the useful guide on the web; however I have some doubts: what about that disc on chip device: how much does it cost more or less? Why can't we use a normal FLASH memory like the ones used to store a standard BIOS? I can think those chips provide particular features, but which ones exactly? Aren't common flash/eeprom chips much easier to find and cheaper to buy? An external programmer could be needed (like for the eproms of etherboot) but most people could have access to such a device. Bye bye and thank you! as P.S. I've read just now that on the pchips motherboard for athlon cpus the L2 cache is not working. Is it true? As the cache is on the processor and not on the mainboard, I thought this wouldn't be a problem...
