Preliminary doubts
by John Praveen 07 Aug '03

Sorry. I donot know whats the problem. I can get mails properly sent through this id. Hi, I have the custom board (geode sc1200) with peripherals like ethernet, PCI audio video decoder, Tuner, hard disk, SDRAM, Flash memory. I will have to have my BIOS program, linux kernel and specific application program in my Flash memory. I have hard disk only for storing files. My Flash memory is of 32 Mbits and SDRAM 32MBytes. I want to use LinuxBios. I build it for nano mainboard. But still I have many doubts. In normal BIOS, we will say the bios program to load the bootloader from hard disk into location 0000:7C00. What part of the program in Linuxbios will bring my linux kernel image from Flash into SDRAM? Is any options or something to be included in the configuration file to say to boot from Flash memory. In my embedded device the Flash memory is mapped to physical address 00000h to 3FFFFFh. So at what location should i place the linuxbios romimage and linux kernel image in my Flash memory? Where shall my application program be placed in Flash? I hope I should have a filesystem. Is the MTD meant for the filesystem? What part of the program in Linuxbios will bring my linux kernel image from Flash into SDRAM? Thanks in advance. Regards, John. --------------------------------- Do you Yahoo!? Yahoo!

It seems the Kernel clear 0x0--4k. Of course after itself take the MP TABLE. Maybe need to update the kernel.

Under 6G RAM linuxbios_tables occupy 0x500-0xaf4, cmos_util can find option_table after power on but can not find it after rebooting. The only difference should be that rebooting don't execute auto.c again. Any advise.

So you will add one module that will produce PIRQ automatically?

In the cmos_util if it can not find linuxbios table from (0--4k) , it will find that from (960k to 1M). Please suggest where we should preserve second copy of linuxbios table.

I always thought it left that page alone, since it's page zero anyway. Well, that explains a thing or two. ron

In Fallback mode, after power on I can use cmos_util. 2. after rebooting it is still in Fallback mode,and can not cmos_util, it said can not find option table in the ram. And can not access cmos.layout. When I using old tool, I can switch to normal mode, but need to change boot_option and last_boot from fallback to normal. regards Yinghai Lu
