So the header add by mkelfImage, bypass the int 15 e820h.

It does not have any mkelfImage bypass that piece of kernel code. We read an equivalent table out of the LinuxBIOS table and pass it to the kernel instead. Eric

Because the NUMA is not mature in Linux, or just X86-64?? YH -----邮件原件----- 发件人: ron minnich [mailto:rminnich@lanl.gov] 发送时间: 2004年4月6日 10:04 收件人: YhLu 抄送: Eric W.

This is the idea behind Eric's linuxbios tables. Also IIRC we do have e820 tables in memory: has linux stopped using them? Linux used to say: "We don't need no steenking BIOS". With the later 2.4.x and 2.6, they seem to be saying "We really need the steenking BIOS". What is going on with Linux? They're moving backwards. We really don't want to support INT type stuff. ron

5705 support

Eric, Etherboot 5.2.4 can recognize the 5705, but when download elf, it does not end. 5.3.7 has the same problem, even in Normal BIOS.

You must prepare 1024 IDE flash one by one at the beginning. It took one week to get it done? YH -----邮件原件----- 发件人: ron minnich [mailto:rminnich@lanl.gov] 发送时间: 2004年4月6日 11:19 收件人: YhLu 抄送: Eric W.

choose_stream can be moved into freebios2. hardware main can call that before elfboot. Need to get boot_order from CMOS and device load which pay load first.

So you must use filo as normal payload and Etherboot as fallback payload. Then if I want to boot from network in normal mode, how to do? Why just merge filo into Etherboot? So we can use tg3--filo.zelf instead of tg3--ide_disk.zelf. Regards YH -----邮件原件----- 发件人: ron minnich [mailto:rminnich@lanl.gov] 发送时间: 2004年4月6日 10:28 收件人: Eric W.

We are using FLASH-based FILO to replace FLASH-based Etherboot on Pink and will be using FILO to replace Etherboot on Lightning and Blue Steel to load images from IDE-FLASH. We are very happy with its capability in that mode. It's just a ton easier for a sysadmin to mount the IDE-FLASH as ext2 and change kernel file names instead of dd-ing raw kernel images onto an IDE-FLASH. FILO lets us treat IDE-FLASH as a file system, and Etherboot had us treating it as a raw disk. We prefer FILO at this point, and I think we will not be the only ones. Also we have found the build procedure for FILO to be less prone to error and problems than for Etherboot. That's not to say Etherboot does not have *many* applications: it is terrific for lots of things, just not for our clusters right now. > Right now I think a bootloader of this type with a config file is > not terribly useful. It is all context. I think we need to turn our thinking a bit. The BIOS you use is going to become more application-specific. What you have in an embedded "black box" will not need to be identical to what you have on your desk or your cluster. I think this is all to the good. ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

FILO 0.4
by SONE Takeshi 06 Apr '04

06 Apr '04

I just released FILO 0.4. http://te.to/~ts1/filo/ It can boot distro CDs if you give a proper command line. SuSE 8.2 LiveEval CD worked without a glitch, I enjoyed the KDE desktop, OpenOffice, etc, from the CD on an EPIA booted from LinuxBIOS. Also added support for booting from BIOS flash, to boot an alternative bootloader like Etherboot. PCI support in IDE driver is also added (or recovered), but the native PCI mode is not fully tested. I tried to configure EPIA (V1) code to use native mode, and the ports read something not 0xff, but the drive doesn't respond to soft reset. I don't know the bug is in FILO, LinuxBIOS, or the hardware. I'll work on config file support next time. Version 0.4 ts1 2003-10-15 * Support for ATAPI CD-ROM. * ISO-9660 filesystem is taken from a GRUB patch by Leonid Lisovskiy <lly(a)pisem.net>. The filesystem code was originally written by Kousuke Takai <tak(a)kmc.gr.jp> for GRUB/98 project. * Support for mounting boot disk image of El Torito bootable CD-ROM. ("hdc1" means the boot disk image of the CD-ROM at hdc.) * Support for memory as device, raw device as image, and user-specifiable device offset and length. (eg. boot: mem@0xfffd0000,0x10000) * PCI support in IDE driver. Now it by default uses PCI enumeration to find the PCI IDE controller, and can use native PCI mode if the controller is configured to this mode by BIOS. To disable this, turn off SUPPORT_PCI. * Fixed Linux loader to boot RedHat 9 kernel properly. -- Takeshi

Eric, Sorry for not replying soon. I've been busy with real job and life, config file support is not yet written, though I'm still willing to do it (+ USB support etc..)

int 15 e820h

Ron, When kernel is loading, it will call int 15, e820h to get memory map. Where does LinuxBIOS put the int 15 e820h processing code? Regards YH

Largest BIOS Workspace
by Don Brown 06 Apr '04

Within BIOS in general and LinuxBIOS in particular, what is the largest workspace available. Are we limited to a 4 meg chip to store LinuxBIOS? Can we build or lever into some larger area? Don Brown, Atlanta GA
