I have got two cpus and four dimms for every CPU. YH _____ From: David Aubin [mailto:daubin@actuality-systems.com] Sent: Friday, July 09, 2004 12:07 PM To: YhLu Cc: Hendricks David W.; ron minnich; LinuxBIOS Subject: RE: Filo Error Help Hi, Yes, I did, but I don't have a DHCP environment so it kept searching at the DHCP phase. This problem is odd. I can boot my elf fine with etherboot, but not with filo. I can boot my kernel fine with filo, but not the initrd. I can even boot your kernel of the ram.elf you sent me, but when it hits the initrd it fails with the same error as mine. I suspect either my filo is not configured like yours or that there is a problem loading a mulitpart elf (kernel & initrd in filo). I'm confused as to why filo didn't just use the etherboot portion of elf_load. It could be you were on the, "bleeding" edge? ;) Can you tell me how much memory you have in your working system? I have just one cpu and 512meg memory. Curious if loading it high & it runs out of memory or something like that.

Finally, I got filo boot into kernel in hard disk, but ...
by Simon Xin Cheng 09 Jul '04

09 Jul '04

Hi, Thanks for everyone who helped me building the LinuxBIOS V2 on epia board. I fixed two problems during trying to use FILO to boot a kernel in hard disk. 1) One memory module is broken. I did not use memtest86. It takes too long time. I just remove a very old memory module, the filo can reach the last step. 2) hard disk should be set as MASTER. It has been set as slave. So I got error message: no IDE dev at channel 0. Right now the booting of kernel stopps at initialize AGP stuff, following is the error message before the kernel crashes: ******************************************** Initializing Cryptographic API Real Time Clock Driver v1.12 Linux agpgart interface v0.100 (c) Dave Jones agpgart: Detected VIA Apollo MVP4 chipset agpgart: Maximum main memory to use for agp memory: 96M 0 LinuxBIOS-1.1.6.0Fallback Fri Jul 9 14:06:03 PDT 2004 starting... *********************************************** I have several questions: 1) DO i need to enable GP_APERTURE_SIZE? And how to set the value? (i.e. by byte or M ) 2) Does the kernel need patch? Right now, I am using 2.6.7 pure kernel. Thanks a lot. Simon Cheng www.msica.com

Status of the EPIA port?
by Adam Hunt 09 Jul '04

09 Jul '04

What is the current state of the EPIA port? I am interested in running LinuxBIOS on a EPIA PD 10000 (as soon as I can find a supplier in the States). Can X be run via the on-board VGA (as apposed to the LVDS). --adam

I could send you my elf, but it is about 6Mb.

Are you certain this initrd is ok? You could try booting the kernel and initrd on a known-good system to make sure the initrd is right. Do you have the right VFS for the initrd build into the kernel? ron

1. which MB? Which USB stick 2. please try .elf at first. It would be uda1:/ram0_2.5_2.6.5_k8.2_mydisk7.elf format your usb disk with FAT or ext2, because it seems reiserfs driver has some problem, and it will not work after abnormal shutdown. 3. I guess td is not be freed right after use. Regards YH

答复: CPU refactoring status....

The hardwaremain become more tidy. How about the progress about the romcc? I hope I can enable debug info while include all ati support stuff.

My gut feel is that I want to > incorporate the sizeram functionality into the resource allocator, Moving sizeram into read_resources/set_resources comes out fairly clean, but it did require some grunt work. That has allowed me to sort out the device tree and have a fairly generic method of initializing cpus. Cpus don't fit into device model methods as nicely as I would like (largely because their methods have to run on the cpu in question). But it does work well enough I can remove the special case from hardwaremain. I still have a special case in the root_device methods but that can be overridden, if necessary. Because I have restructured where things fall in the device tree. Because I have removed the sizeram call. Because I have refactored x86 cpu handling. Because I have removed the array initial_apic_id. Every port in the tree is likely to break when I check this code in. I have the arima/hdama working and I can with a little care fix up the k8 based ports. I can also likely fixup the recent e7501 forward port from the freebios tree. However beyond that I don't have testing resources to fix things up so I am looking for some feedback before I break everything. When in the next week or so is a good time? Does any one have concerns about this set of changes? I have attached my current version of hardwaremain below to give a feel of what the changes look like. Ok now I am off to bed.
