Eric, If the put the etherboot and filo in the ROM at the same time for fallback mode, Is it possible to make payload be selected by the elfboot? ( Controlled by cmos layout or key) Or let the Etherboot load another elf in ROM instead of HD? ( in the boot option add BOOT_ELF or BOOT_ZELF together with BOOT_NIC, BOOT_DISK, BOOT_FLOPPY).

What about the following: Currently LinuxBIOS divides into 2 fundamental parts: 1) hardware initialization 2) getting and starting the payload This second part consists of two parts, again: i) elfloader ii) payload Note, this is only one possible design. Maybe, this design is bloated for some application cases. Eric, you want to make a hard cut between what is LinuxBIOS and what is not. This is generally a good idea, as it keeps the different initialization steps distinct from reach other. What, if we add another cut by dividing hardware initialization frin the payload-loader? Instead of packing stuff like filo to util, we could do: * create a directory loader which can hold all "loaders" * move the elf loader with a Config.lb to a subdirectory in there * create other directories for other "loaders" like filo. If done right, filo can still be compiled as a payload, or built in if the win in size is noticable. A target config file could probably choose which method to use, without overhead. Also, syncing with other trees, like Takeshi's filo tree could be fairly easy, too. I don't think we really have a conflict in direction here at all. LinuxBIOS itself should be as small as possible, and the different parts should be as independent as possible. But we also want to be a lot more flexible than the existing solutions.. > In addition we have had way to many questions of what is the right > policy for a bootloader to implement, on this list.

Please explain, how is filo worse here than putting linux in flash? Stefan

Sone, You may add the zelf make option as Etherboot to make payload smaller.

Can I execute a linuxbios image from linux?
by Svante Signell 02 Apr '04

02 Apr '04

Hello, I'm trying to upgrade the CPU on a 440BX dual board MSI-6210 from dual Celerons (Mendocino) to a single Celeron2 (Tualatin) using a socket 370 to slot 1 adapter, SLOT-T from Upgradeware. On other 440BX based motherboards, this works perfectly. Two computers I have upgraded are a QDI BrillianX 1 based box and the Compaq 5670. The lates BIOS for the 6120 does not support Coppermine or Tualatin processors. With the 6120, I get a successful boot too, but the effective speed is 7 MHz as compared to expected 1.3GHz (measured with lmbench). I have made a small kernel module testing the level 2 cache activation code, without any improvements. Also mtrr seems to be set up correctly. Now I would like to execute a full linuxbios image after boot to linux, in order to avoid the problem of re-flashing the BIOS. Is this possible? The Upgradeware support pages mentions that the IO chips have to be of correct type for a similar single CPU board, the MSI-6119 to uork with the SLOT-T adapter. What function does the IO chip have, and how can in be tested? Thanks, Svante

Linux Startup Times
by John Usher (Maptek) 02 Apr '04

02 Apr '04

Hi all, Its a bit off topic, but has anyone here done any work on reducing the Linux startup times? Linux on our systems is taking more than 10 seconds to start, and I guess its due to it searching for devices and the like. Any pointers to any resources or information to assist with reducing these times would be great. ...John...

unreliably booting off a BCM5701.

abit SI-1Ns
by Michael Hale 01 Apr '04

01 Apr '04

Hi all, I have an abit SI-1Ns with an intel 845GV chipset. I would like to put linuxbios on this board... but according to the status page it looks like this board is not supported. I am an applications programmer, not a hardware programmer... so I am somewhat at a loss as to where I should start. Can someone point me in the right direction for getting linuxbios running on this board? Thanks, Michael

VIA EPIA question
by root 01 Apr '04

01 Apr '04

hello, I've been watching an reading a lot in this interesting adventure... I've been trying to get Linuxbios work first on a SiS530 but through mailing list, tree docs, and surroundings i didn't find out enough support on this. So i decide to switch to another board that have been greatly tested. I am willing now to make LinuxBios work on a Apollo PLE133 mainboard, this is a VIA EPIA chipset based motherboard (http://www.viavpsd.com/product/epia_mini_itx_spec.jsp?motherboardId=21) 00.0 Host bridge: VIA 0601 (rev5) 01.0 PCI bridge : VIA 8601 11.0 ISA bridge : VIA 8231 11.1 IDE interf : VT82C586 (rev6) 11.2 USB interf : VT82C586B (rev 1e) 11.3 USB interf : VT82C586B (rev 1e) 11.4 Bridge : VIA 8235 (rev10) 11.5 audio : VIA 3058 (rev 40) 12.0 Ethernet : VIA 3065 (rev51) 1:00.0 VGA Trident: 8500(rev 6a) on a via C3 CPU working kernel 2.4.18 I'am looking for a kernel patch for VIA Epia on this kernel but couldn't find one. Would it mean it needn't a fix ? Also wandering on a "easiest" way to get my config work : on v1 or in v2 (I got to take care of the portability with v1-v2 issues?) Knowing that at the end (of this adventure:) I will make it boot on a M-DoC 2000... yet firstly I'll burn a bios chip and boot a IDE HD... step by step :) This is a RFC, so anything helpful on my methods, developpement risk, wayouts, adviced other docs are very welcome Thanks.
