ROM-Size-Problem
by Thomas Leidenfrost 07 Aug '04

07 Aug '04

Hello list, here's my actual config-file, but somehow the resulting linuxbios.rom is only 64 kB instead of 256 kB, although setting: "option ROM_SIZE=262144" Filling the Linuxbios.rom to 256 kB with zeros (dd if=/dev/zero bs=1k count=192 >> linuxbios.rom) or with itself three more times (cat linuxbios.rom linuxbios.rom linuxbios.rom linuxbios.rom > bios256.rom) doesn't work, the monitor displays nothing (is framebuffer neccessary for that?!). So, how to make the generated linuxbios.rom will be 256 kB? Thx, Tom target testawb651 mainboard ics-d/awb651 # Enable Serial Console for debugging option SERIAL_CONSOLE=1 option TTYS0_BAUD=38400 option VIDEO_CONSOLE=1 option DEFAULT_CONSOLE_LOGLEVEL=9 option DEBUG=1 # option HAVE_FRAMEBUFFER=1 option USE_GENERIC_ROM=1 option USE_ELF_BOOT=1 option ROM_SIZE=262144 option STD_FLASH=1 linux /stuff2/Linuxe/kernel2422 commandline root=/dev/hda1 console=ttyS0,115200 FS_MODE=ro hda=flash

Freebios2 amd/serenade keyboard init error
by Stephen.Kimball＠bench.com 02 Aug '04

02 Aug '04

I have built LinuxBIOS for the amd/serenade target and I get about 600 lines of good output to the serial port, which ends with Initializing devices... PCI: 00:18.0 init PCI: 00:18.3 init NB: Function 3 Misc Control.. done. PCI: 00:19.0 init PCI: 00:19.3 init NB: Function 3 Misc Control.. done.

PC80/keyboard.c is trying to initialize the keyboard. The code that is running is /* empty input buffer or any other command/data will be lost */ while ((inb(0x64) & 0x02)) post_code(0); The inb(0x64) reads 0xff forever. I heard that the keyboard initialization may not be needed. How can I fix this? Thanks. Steve

Linux from NTLDR
by Digital Infra, Inc. 31 Jul '04

31 Jul '04

(Doublely posted to Grub and LinuxBIOS ML. Tell me which is appropriate.) Hello. I am working on booting Linux from NTLDR. I mean, you dont have to install a Grub on your MBR. Check this: http://denbbs.angelskyarea.com/YaBB.cgi?board=discuss;action=display;num= 1087892282;start=180 First, I want to hear your opinion about it. And I appriciate much if you give me even hints of development. Second, Do you know a small Linux kernel build which runs as one relocatable binary file? In other words, vmlinux.com. Of course, I use .com here as not internet, but MS-DOS word. Okajima, Jun. Digital Infra, Inc. Tokyo, Japan. (Japanese native can mail me directly with Japanese lang.)

Tony, Thanks. It worked. Instead I commented out the code in keyboard.c inside init_pc_keyboard(), since there are several versions of superio.c. Not sure which is used.

A quick question...
by Mike McWhorter 26 Jul '04

26 Jul '04

I checked the LinuxBIOS status page to see if my motherboard is supported, but I found it to be a little confusing. I'm using an older Dell Optiplex and (based on the lspci output) I believe it uses the Intel 440BX chipset. Does anyone know if this board is supported?

RE: AMD 8111 GPIO
by Jay Miller 26 Jul '04

26 Jul '04

The GPIO pins are I/O mapped at an offset from the Power Management base address. The PM base address is at the second PCI device, function 3, offset 0x58. On a typical PC-BIOS this value is usually 0x5000. But when I do an lspci -xxx on a system running LinuxBIOS the value at offset 0x58 is 0x0000. I guess the question now is, does LinuxBIOS setup the PM base address?

You can use FILO in Etherboot to get boot from USB (UHCI and OHCI). https://sourceforge.net/tracker/?func=detail&aid=943300&group_id=4233&atid=3 04233 Next step maybe EHCI support.

RE: sis630et memory init problem
by zhu shi song 25 Jul '04

25 Jul '04

Sir, (1) On my sis630et board P6STMT, bios value of 0x8E is 00 (2) if I set 0x8E to 00 in IPL, ipl hangs on using stack to read linuxbios from DOC to ram (3) if I set 0x8E to 03 in IPL, linuxbios can start linux image successfully, but linux hangs at random time. (4) conclusion IPL init SDRAM has some trouble, memory can't work stably. It's so strange I have setted the values after the bios values. Is there any trick to init SDRAM on SIS630ET? tks zhu Nick Jarmany <nick.jarmany(a)densitron.co.uk> wrote: Zhu, On SiS630ET x8Eh has two active bits:- Bit 0: SDRAM synchronous mode. 0=Enable, 1=Disable Bit 1:Relationship between CPU & SDRAM clocks. 0=CPU>SDRAM, 1=CPU<SDRAM Default value of this register at POR=00h Regards, Nick -----Original Message----- From: linuxbios-admin(a)clustermatic.org [mailto:linuxbios-admin@clustermatic.org]On Behalf Of zhu shi song Sent: 25 July 2004 11:10 To: linuxbios(a)clustermatic.org Subject: sis630et memory init problem Hi, lists, I've got one ECS p6stmt motherboard based on sis630et.
