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

Level 2 cache activation code?
by Svante Signell 04 Dec '03

04 Dec '03

Hello, I have recently upgraded my dual MSI-6120 from 2xCeleron (Mendocino) 300@450MHz with 2xMSI-6905 slot 370 to slot 1 adapters to one Celeron2 1.3GHz (Tualatin) using a Slot-T adapter card. The plan is to equip the mobo with 2xPIII or preferably 2xVIA C3 Nehemiah (when SMP capable). The problem is that the latest MSI BIOS (v2.0) for the mobo does not support Coppermine/Tualatin processors. The single GNU/Linux kernels boot without problems but _extremely_ slowly, at least with a speed reduction by a factor 10. hdparm -tT gives around 20/2 compared with 250/25 with the Mendocino CPU(s). For example uncompressing the kernel takes minute(s) compared to seconds. After some trials and web searching I suspect that the problem is with the level 2 cache not activated by the BIOS. I see the you have code in the linuxbios for activating caches. i) Does this code work for 440BX motherboards? ii) Is it possible to extract this code and try out after the kernel has booted (slowly), to verify my assumption? iii) Is there some other tool available for cache activation? iv) One interesting continuation would be to try to replace the MSI (AMI) BIOS with linuxbios, but as a first step I think this would be a little risky. Any ideas? Thanks, Svante

Hi linuxbiosians, Heard and Read that Windows 2000 can be booted using Linuxbios. Keeeeeeen and Interested in entering linuxbios. Could i get the list of OS's booted using LINUXBIOS and a brief explanation document along with it ? or links plz.... I am stilll looking for a motherboard in Chennai,INDIA Has anyone tried linuxbios in CHENNAI,INDIA ? need your support to start linuxbios with.

So need one customerization Installation image to execute the sh to install conf file. Also the kernel in the installation image should support X server without VGA init.

If the user writes the FILO configuration file. It will be possible that FILO loads the configuration file from distribution CD and boot from the CD almost automatically, and the distribution installer creates the FILO configuration file on the hard disk, so the machine will boot from hard disk next time. (the default location of the config file can be saved in CMOS) So the LinuxBIOS pre-installed workstation will be possible. -- Takeshi

SONE, What is the FIFO URL and the status? Is it some kind payload for LinuxBIOS?

Sone, So if the user installed the Linux Distribution to HD in normal BIOS and after that he flash the ROM to LinuxBIOS with FIFO and the system call work without any problem.

FILO loads vmlinuz and ELF kernel from filesystem (like ext2) on the local IDE hard disk, CD-ROM, CompactFlash, or ROM. It's working well on my EPIA, and also reported to work with K8 based boards including Tyan's. See this for details: http://te.to/~ts1/filo/ My plan is to add support for configuration file, so the default kernel location and parameters will no longer be hard coded in the Flash, and Stephan told me maybe he can support this config file in the future releases of SuSE installation CDs. -- Takeshi

Re: running out of registers

To confirm where you are running out of registers I would suggest commenting out the code in question to see if it compiles without it. Knowing that should help craft a solution. Depending on the nature of the problem and how we are running out of registers it might make sense to store a couple of values in a single variable. If you want to keep it from running forever before it gives up I suggest -fmax-allocation-passes=8 -fdebug-live-range-conflicts. The -fdebug-live-range-conflicts is not terribly interesting except it tells you how many passes romcc goes through before it gives up. The -fmax-allocation-passes=8 sets the limit on the number of register allocation passes romcc will use. The most I have seen it make and succeed in my regression tests is 6. And the default is 100.

help with filo
by Russell Gower 30 Oct '03

30 Oct '03

I'm trying to use filo to boot from a cdrom which is on hdb, it looks to me that using boot: hdb1 should do it but i'm getting Unsupported sector size 2352. Eltorito is enabled in the Config file. any suggestions? ICQ 4186920
