Does linux care the PCI IRQ tables created by LinuxBios? I thought it only look at the MP-table. gin

totalimpact briq?

Hi, how should the totalimpact briq target work? When I build it, I get an elf image as the resulting linuxbios.rom. Is this intended? Stefan

That could solve some problem about font memory initilization. But I guess the problem is about Emulator, and Ron is digging that on S2885 now. With LinuxBIOS (enable VGA and copy that to RAM but don't run_BIOS) + test bios. Stefan, What's the onboard VGA? are your talking about onboard one?

Hi & 440lx chipset
by Paul Millar Feb. 12, 2005

Feb. 12, 2005

Hi, Quick (cheeky) question: does LinuxBIOS support the 440LX chipset? MSI/AMI no longer support it (probably for some time now), and the most recent BIOS has some difficulty with "large" disks: anything much over 3G kills the boot sequence. Cheers, Paul. PS I'm getting a 404 when trying to fill in the help web-form: /cgi-bin/linuxbios/help.cgi not found.

VIA EPIA FILO boot problems

Re: Via EPIA-MII ROM speed?

FILO load is very fast. FILO can be 32KB and it's coming out of flash. I would say for your purposes it is 0. FILO scanning for IDE will be fast on EPIA. The only real time kill is "spinning" up the hard drive, which on CF is also pretty quick. ron

-Richard. Thank you for some real numbers. Ok, a few note to add to your very good description of the issue at hand. I found that my hard drive has a spin up time of about 3~5 seconds so thats out of the picture. Solved that issue by switching from a HDD to a Compact Flash (CF), no spin up, almost no seek time. The board (Via EPIA-MII) has a built on CF slot. Linux bios allowed me to boot from the CF. Also there is one other number we need to look at. How long does it take for FILO to load? I have no clue on numbers for FILO. The 2 step process LinuxBios à kernel (LBK), or the 3 set process, LinuxBios à FILO à kernel (LBFK). In the LBFK process all the transaction are faster, but the second step my slow down the process long enough to make the LBK process faster. I am not very sure here and there are still just ideas and I need to do some real testing. In the long run I may be forced to use LBFK as the smallest 2.6 kernel I have been able to compile comes in at 404k+linuxbios > ROM. I think 512KB is the biggest ROM chip out there that will work with this board. -Adam -------------- Original message -------------- > On Fri, 11 Feb 2005 08:32:43 -0800, Adam Talbot wrote: > > How fast is the ROM chip MB/s.
