Hi guys, I've finally built linuxbios for my SC1200 based board. I've written my own flash programming utility so I can program the "romimage" file produced into my flash part from Linux command line. This all seems to work fine. On my board, I have the ability (with a jumper) to direct the ROMCS# signal to one of 3 chips on the board. One is a Disk on Chip which currently has a DOS filesystem on it, one is a 2Mbit flash chip which has the original Insyde BIOS, and the 3rd is a 16Mbit flash part soldered on the board where I'm trying to put linuxbios. This 3rd chip is at 0xffe00000 - 0xffffffff, in order to enable this addressing I must hit bit 2 in F0 offset 0x52 to enable the Upper ROM size based on the ROM Mask at F0 offset 0x6e. This isn't enabled by default so I think as the chip comes up only 0xfffc0000 - 0xffffffff is visible. I'm not 100% sure, but I assume as the chip comes up it starts trying to fetch instructions from 0xfffc0000, is this true? My question is, where should I program the "romimage" file that comes out of the build process? It would seem to me that the linuxbios.rom part would have to start at 0xfffc0000. Other notes: I've set up my PMR and MCR registers correctly for my target. I figured them out by hand and then verified their values when I run with the Insyde BIOS. So I'm 100% sure the values I'm using are correct for my target. I've set the SCx200_DOCCS_BASE to 0xffe00000 for the moment and the CTRL to 0x070007ff I'm not sure if the BASE value is correct due to the questions I pose above. All of my efforts have resulted in nothing happening at startup. Nothing out of the serial port nor are the Port 80 codes moving after the board is reset. Any ideas/help would be appreciated. Thanks and have a happy new year. Adam

Why bios(generic) is slow?

Hi Can you tell me why generic bios is so slow compared to linuxbios. In other word, why linuxbios is fast? I think "do little thing" is not enough to explain x10 time difference. What does bios do other than linuxbios does and where it spend so much time? Regard, Heechul - HeeChul Yun, Embedded S/W Team at ETRI phone: +82-42-860-1673

Hi, Please find the details of the motherboard as requested. Could you Please let me know if linuxbios would be supported and how to go about it. ****LOG*** [root@pc5585 /root]# lspci 00:00.0 Host bridge: Intel Corporation 82810E GMCH [Graphics Memory

Documentation
by John Allen 03 Jan '03

03 Jan '03

All, I have been working with LinuxBIOS on my Geode for several weeks now. I would first like to say, "I love it!". If does what it is intended to do very well. The only drawback I see is documentation. After watching the mailing lists for these past few weeks, I believe that most issues could be solved with some updated and decent docs. As a LinuxBIOS newbie, myself, I found trying to determine the correct option flags nearly impossible. It would be great to at least have something that described what each option did. For example, BOOT_IDE, BOOT_TFTP, USE_ELF_BOOT, USE_GENERIC_ROM, and others could be grouped together to decribe where LinuxBIOS gets the kernel image. I would be willing to help get the docs inorder, but as a relative newbie to LinuxBIOS, I probably know only a handful of options anyway. Any Thoughts? John

Hi, I want to understand the flow of the following piece fo the code. It is for copying the Linuxbios image from Flash ROM to RAM. Here I want to what is the value of the _liseg, _iseg, _eliseg segment address. Can any one explain the following code. My system hangs in this part of code (i.e. at rep and movsb instruction. As per the Ron's SUGGESTION I also used spd to get the value for RAM intialization. But still it loop at this point jz .Lnocopy movl $EXT(_eliseg), %ecx CONSOLE_DEBUG_TX_HEX32(%ecx) subl %esi, %ecx jz .Lnocopy /* should not happen */ rep movsb CONSOLE_DEBUG_TX_STRING($siva_debug5) .Lnocopy: Thanks, Siva.S /* * Copy data into RAM and clear the BSS.

Adam, I am also working on a board that integrates the Geode SC2200/SC1200 chip. I am not sure if I can answer your questiuon, but I am interrested in how you programed your flash. I was planning on trying the /dev/bios utility before I attemted to do it on my own. Have you look at this utility? http://www.freiburg.linux.de/OpenBIOS/development/devbios.html John

booting from usb?
by Nicholas Mistry 02 Jan '03

02 Jan '03

As being a novice when it comes to linuxbios, i was wondering what would need to be done to have linuxbios be able to boot from a usb device? IE: usb cdrom, usb HD, usb CF reader, usb pen drive, etc.... Is this something that would have to be done (or would be better accomplished) after linux loads its usb drivers, etc.. ?
