It seems the last 64Kbytes is write_protected by GPIO. YH

You need to check if your kernel has 1. correct partition type support 2. correct fs type support ( like rich said, ext3 etc) YH -----Original Message----- From: Myles Watson [mailto:myles@mouselemur.cs.byu.edu] Sent: Friday, October 13, 2006 12:11 PM To: Lu, Yinghai; myles(a)mouselemur.cs.byu.edu; 'Richard Smith' Cc: linuxbios(a)linuxbios.org Subject: RE: [LinuxBIOS] Tyan s2892 the OLPC way >You need to enable smp in the kernel to get apic enabled.

You need to enable smp in the kernel to get apic enabled. And use maxcpus=1 if you only need one cpu running.

It works for a different kernel through the filo etherboot pathway, so I'm wondering if I've misconfigured the kernel. Do I need to explicitly support the Opteron? I'm using a 32-bit kernel because there are no linux-tiny patches for 64-bit. Myles -- linuxbios mailing list linuxbios(a)linuxbios.org http://www.openbios.org/mailman/listinfo/linuxbios

You kernel command line may need to include "apic" to enable the apic mode. YH ________________________________ From: linuxbios-bounces(a)linuxbios.org [mailto:linuxbios-bounces@linuxbios.org] On Behalf Of Myles Watson Sent: Friday, October 13, 2006 9:42 AM To: linuxbios(a)linuxbios.org Subject: [LinuxBIOS] Tyan s2892 the OLPC way Pointers? I've used OLPC buildrom as a base, customized the kernel to include the SATA drivers, IDE, EXT2, EXT3. I removed the boot menu and successfully boot into a shell with pciutils. I can't mount my IDE hard drive, even though I can see it in the /proc filesystem. I'm trying mount -t ext3 /dev/hda1 /hdd. When I do an lspci, all the IRQs are routed to IRQ 0. I don't know if this is the root of the problem, or a symptom. How can I make sure that the PCI settings that I set up in LinuxBIOS get passed on? Thanks, Myles An unrelated note for those that are into OLPC: in linuxrc two of the device files get made as text files because they are not there early enough in the process /sbin/makedevs /dev < device.txt > /dev/null is bad because it creates a text file where /dev/null should be. The same thing happens to /dev/console in a different place.

Try adding delay(5); (5 second delay) in main in filo.c (if you use grub). Put it after the init() call. If that does not help, try 10 or 15 seconds. Thanks, Ward.

It turns out FILO need 45s to find the WD 40G HD, and Kernel need 15s. For the 200G WD HD, FILO and Kernel need less 1 second to find it. Looks like CK804 SATA is picky for SATA disk too. It can not find some sata disk.

I didn't notice that. I booted with Etherboot from network, and the kernel can find the HD and mount it. I will check if my filo like the IDE. YH
