Ok, I will add my 2 cents. This is my setup. 1. Linux bios configures the MB (takes about 1-2 seconds for me and my Tyan) 2. Then it loads etherboot (add maybe another second here) 3. Etherboot remotely loads Kernel from a machine already running thus saving disk spin up time (4-5 seconds) A. I suppose you could have this in RAM and send over a gig pipe or 10 gig pipe if speed is an issue 4. Then Kernel runs (5-10 seconds later) 5. Bash prompt with a well configured linux system What is great about Linux bios is it is flexible. It is also faster than my standard bios as it doesn't Do memory checks and such. It just get's right on to it. Although you can add in your own tests in the Bios or in the payload area. FYI: I've heard a bproc setup gets going in about 10 seconds from power on to running. Here is an even faster plausible setup, you can't do this with a proprietary bios;) 1. Linux bios configures the MB (takes about 1-2 seconds for me and my Tyan) 2. Then it jumps to the linux kernel itself embedded on the BIOS itself 3. Kernel is done loading about 5 to 10 seconds later and you're at cli prompt. This is an ideal case for speed if you have a big enough bios size. M-Tech is Supposed to have an LPC interface to their DOC (disk on chip). This would have made My life so nice, but as far as I know it isn't ready yet. Hope this helps. Oh and the support from this email list is quite awesome. People Here always help me so I try to return the favor as much as I can. Dave -----Original Message----- From: linuxbios-admin(a)clustermatic.org [mailto:linuxbios-admin@clustermatic.org] On Behalf Of linuxg33k Sent: Thursday, September 09, 2004 9:59 PM To: linuxbios(a)clustermatic.org Subject: about linux, linuxbios and bootup times Hi everyone. I'm a new member, I joined the list to learn more about the Linuxbios project. A question for anyone that can point me in the right direction to information: Q: I read everything on linuxbios.org as well as googled until i got a nosebleed, but i can't find any real world examples of linuxbios + linuxdistro setups. I am looking right now to purchase a linux bios compatable mobo based on the list from linuxbios.org to play around with, but what i was wondering is, just how can linuxbios speed up the boot process of a linux based system? Pardon my newbieness, but I have never had a bios be anything more than a fraction of the total bootup time on any linux system, so does linuxbios have the capability to litterally boot a linux system to cli login prompt of any distro within seconds or not? I realize it's a general question, assume I'm running debian base install ( no x, no desktop environment, boot staright to command line), most of the bootup process is taken up by the bootup scripts checking the hardware and starting up various services (I probably have too many and unoptimized i'm sure but thats another issue alltogether). From everything that I have read, I am understanding that basically its a faster bios that jumps to the distros bootloader when done? Or does this redefine the bootup process where the linuxbios is the bootloader and upon coming to life jumps straight to the distro kernel? If it jumps to the distro bootloader surely the time savings are a few seconds at best? If linuxbios takes over some of the bootloader functions, how does this affect a typicall install if at all? Sorry for the overgeneralized questions, I just need a few answers here, even if vague to help me create a knowledge sandbox into which i can then drill down to proper understanding. By the way, i read an article recently of an interview with the president of Tyan. According to the interview Tyan will be shipping all motherboards with Linuxbios. I have no idea if they are using the real deal from cvs, or forking it, or what, but goddamn that really cool stuff. I'm hoping some of the answers to my question will mean that linux on the desktop has a bright future vis a vis Tyan at least. If anyone wants a copy of it, email me and I will attach the html document - I knew they would take it down as indeed they have. Thanks aforehand!!!! - Rob _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

epia m vga XFree86 4.3 works update
by Trellix78＠aol.com 09 Sep '04

09 Sep '04

It's obvious that something strange is happening with AGP and XFree86 4.4. The latest patched driver for the epia M crashes in backend.c, function agp_backend_initialize() of the agpgart driver, at bridge->driver->configure(). Commenting out that line will enable the driver to be installed but Xwindows will crash hard while attempting to play mpeg videos. I was able to use AGP stuff posted by Dave Ashley in "Question about AGP (epia-m)" post but my system will not crash everytime will attempting to set the graphics aperture size. Since this is getting into kernel issues, I'll simply post the log that I have, grab V2 and start from there. Thanks.

port linuxbios(v1) to i845GV based MB
by zhu shi song 09 Sep '04

09 Sep '04

intel i845GV is very popular now. I've got P4i45GV MB based on i845GV(northbridge:i845GV, southbridge:82801db, superio: winfast w83627hf ). I try to port linuxbios(v1) to this board. Today I have built my first romimage for it. There met one problem when using it to boot. Serial output is unreadable code. I have checked the baud rate it's ok. Maybe setup_serial has some bug. tks zhu _______________________________ Do you Yahoo!? Win 1 of 4,000 free domain names from Yahoo! Enter now. http://promotions.yahoo.com/goldrush

Well, I'm definitely making some progress with the epia m vga. I downloaded the very latest freebios from CVS and I see that I was indeed missing the shadow copy stuff in mainboard.c and also, I was using the wrong value for the vt8623 PCI id. Now, I have a different problem. I'm able to get XFree86 4.3 to start up on tty0 but it complains about AGP, DRI and linear memory. I believe there's a post about that but it didn't mention a fix. I get no output on the monitor until then. Adding AGP support in the 2.6.6 kernel causes the system to hang after the driver is loaded. I'll compile a 2.4 kernel + maybe enable framebuffer support in the kernel to test. Other things that I've tried so far is to enable VIDEO_CONSOLE and the fixup code but I still don't get any output prior to X starting up. I'm currently clueless about why video mode + PCX loading stuff can be done even before the PCI stuff. The upside to all this is that I'm now very familiar with the code. I know there's stuff in the FAQ, but would anyone object if I posted a map of the code for the epia m from entry16 all the way to elfboot() as an example? I've drawn such a map to help navigate through the directories and code and IMHO all the cool stuff happens at hardwaremain(), anyway. Cheers and thanks for all the help.

RE: Windows over LinuxBIOS

Hi, Read this: http://pcburn.com/article.php?op=Print&sid=62 ________________________________ From: linuxbios-admin(a)clustermatic.org [mailto:linuxbios-admin@clustermatic.org] On Behalf Of Dave Belt Sent: Wednesday, September 08, 2004 9:02 AM To: linuxbios(a)clustermatic.org Subject: Windows over LinuxBIOS I have a customer building a custom PC based board. I have been presenting LinuxBIOS as a viable BIOS option; however, they have a serious interest in running Windows, likely 2K & XP, on this board. Does anybody have experience in this area to share? I'm currently trying to get a grasp of the effort required beyond the LinuxBIOS port itself. Also, what kind of reliability are you getting with your implementation? Any info you could provide would be much appreciated. Thanks

RE: port linuxbios(v1) to i845GV based MB

I suggest you start the work from freebios2. The similar northbridge E7501 is already there. You may just need to change some pci_write_conf32 to mem io for memory controller initialization. Other 82801er and Winbond 83627hf is there too. The Mainboard is tyan s2735.

I've got P4i45GV MB based on i845GV(northbridge:i845GV, southbridge:82801db, superio: winfast w83627hf ). I try to port linuxbios(v1) to this board. Today I have built my first romimage for it. There met one problem when using it to boot. Serial output is unreadable code. I have checked the baud rate it's ok. Maybe setup_serial has some bug. tks zhu _______________________________ Do you Yahoo!? Win 1 of 4,000 free domain names from Yahoo!
