now i can boot my ec3 mainboard, but linuxbios can only find 32M ram, but I have 256M RAM. do you meet such problem? ec3 mainboard specification: processor: on-board NS GX1 233MHZ(fanless) chipset: NS CS5530A System Memory: one SDRAM DIMM BIOS: 2Mbit Flash BIOS solid state disk: support diskonchip 2000 --------------------------------- Do you Yahoo!?

2 questions.. 1. laptops and linuxbios, 2. bios-savior for laptops?
by Nicholas Mistry 21 Feb '03

21 Feb '03

ok, sorry for the dual post, but they are somewhat related. 1. I havent really put much thought to using linuxbios on a laptop, but a recent post has planted a bug in my brain to try and get it to work on some of the older laptops i have laying around. How many people have tried to get linux bios on their laptops, and how well does it work. this issue now prompts this quesion: 2. What type of "bios savior" options are there for laptops? or is that just a pipe dream at this point? -N

Hi, i'm new in the list and i'd like know more things about put Kernel Linux in flashrom. 1) i'd like know a right map of a flashrom.At the moment i know that Bios code start at 0xf000h in 16 bits mode, in 0xc000h, there is VGA bios. 2) i want test your work with simulator like bochs, is there some document to try it ..? Yes, i well-read the information in your web. And all aditional docs will be a good thing. Thanks. Xavi.

RE: how to choice fallback or normal image?
by Terry B. Chen 21 Feb '03

21 Feb '03

I read the code in cmos_failover.inc But I don’t understand that RTC_BOOT_BYTE bit 1 gets the value from bit 0, the program clear bit 0 every time. But When to set the bit0 to 1, it will make the code jump to normal image next time? I search 0x70(cmos index) in all but I cant find when set bit 0 to 1? -----Original Message----- From: steven james [mailto:pyro@linuxlabs.com] Sent: 2003年2月20日 23:27 To: Terry B. Chen Cc: linuxbios(a)clustermatic.org Subject: Re: how to choice fallback or normal image? Greetings, Several conditions need to exist for the primary image to be used. The code looks at the RTC register to check for indication of power failure (either battery dead, or clear CMOS jumper set), then the CMOS checksum is checked. If both tests show that CMOS is valid, then check the RTC_BOOT_BYTE. First, bit 0 is moved to bit 1 and bit 0 is cleared. Then, if bit 1 is set, call the primary (normal image), That is done so that if the boot fails for some reason, it will choose the fallback image next time. It is also possible to cause a fallback boot by setting the clear CMOS jumper. The RTC_BOOT_BYTE is not included in the checksum since it will be changed wi8th every boot. Note that on some boards, the CMOS checksum is skipped. G'day, sjames The RTC_BOOT_BYTE On Thu, 20 Feb 2003, Terry B.

How to initialize USB controller in LinuxBios?
by riskin＠263.net 21 Feb '03

21 Feb '03

Hi,ollie, My kernel is "2.2.14",so I need to initialize USB controller in LinuxBios. But,I don't know how to correctly initialize USB controller in LinuxBios on the sis630e chipset. I have checked the USB pci config space on the sis630e chipset, so I assigned "I/0" addresses "0xd001<<12" and "0xd8001<<12". And,the function number of the tow USB controller is 2 and 3. So,I modified LinuxBios like following: void pci_usb_enable(unsigned bus, unsigned slot, unsigned int irq) { unsigned functNum; struct pci_dev *pdev; unsigned char line; unsigned char readback; u32 io[2]={0xd001<<12,0xd801<<12}; for (functNum = 2; functNum < 4; functNum++) { pdev = pci_find_slot(bus, (slot << 3) + functNum); if (pdev) { pci_read_config_byte(pdev, PCI_INTERRUPT_PIN, &line); printk_debug("USB PIN: %d\n",line); pci_write_config_dword(pdev, PCI_BASE_ADDRESS_0, \ io[functNum-2]); pci_write_config_byte(pdev, PCI_COMMAND, \ PCI_COMMAND_IO | PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER); if ((line >= 1) && (line <= 4)) { printk_debug("Assigning usb IRQ %d to %d:%x.%d\n", \ irq, bus, slot, functNum); pci_write_config_byte(pdev, PCI_INTERRUPT_LINE,\ irq); pci_read_config_byte(pdev, PCI_INTERRUPT_LINE, \ &readback); printk_debug(" Readback = %d\n", readback); } } } } ... pci_usb_enable(0,1,0xa); ... After done this,I looked up /proc/pci: PCI devices found: Bus 0, device 0, function 0: Host bridge: Silicon Integrated Systems Unknown device (rev 33). Vendor id=1039. Device id=630. Medium devsel.

how to choice fallback or normal image?
by Terry B. Chen 20 Feb '03

20 Feb '03

Dear all: I was puzzled by the fallback and normal image in s2722 (e7500), I am sorry to ask so simple question. When shall we use the fallback image and when shall we use the normal image? How you control which to run? The register DRC (7c) bit 29(Init complete) seem not to be set after memory initialization complete. am I right? Thank you!

option_table ?
by Terry B. Chen 20 Feb '03

20 Feb '03

Hi all, I have a question about option table; the utility "build_opt_tbl.c" will give us an option_table.c automatically, but where is the option_table [ ] used? How to control my Linuxbios go to fallback or normal image? We always run in fallback image. Can someone give me some suggestions? The code is in file reset_test.inc and cmos_failover.inc. The code total is " #define MCH_DRC 0x7C #define DRC_IC (1 << 29) /* If I have already booted once skip a bunch of initialization */ /* To see if I have already booted I check to see if memory * has been enabled. */ movl $MCH_DRC, %eax PCI_READ_CONFIG_DWORD testl $DRC_IC, %eax setnz %al testb %al, %al jz __failover_boot __failover_reset: movb $RTC_BOOT_BYTE, %al outb %al, $0x70 inb $0x71, %al testb $(1<<1), %al jnz __normal_image jmp __cpu_reset __failover_boot: /* See if the cmos clear jumper has been set */ movl $((RTC_DEVFN << 8) | GEN_PMCON_3), %eax PCI_READ_CONFIG_DWORD testl $RTC_FAILED, %eax jz __cs_test /* There are no impossible values, no checksums * so just trust whatever value we have in the * cmos. */ __rtc_failed: movb $RTC_BOOT_BYTE, %al outb %al, $0x70 inb $0x71, %al andb $0xfc, %al outb %al, $0x71 jmp __cs_test /* test the checksum */ __cs_test: movl $77,%ecx xor %ebx,%ebx movl $RTC_BOOT_BYTE, %edx 1: addl $1, %edx movl %edx, %eax outb %al, $0x70 inb $0x71, %al addl %eax,%ebx subl $1,%ecx jnz 1b not %ebx addl $1, %edx movl %edx, %eax outb %al, $0x70 inb $0x71, %al movb %al,%ch addl $1, %edx movl %edx, %eax outb %al, $0x70 inb $0x71, %al movb %ch,%ah cmpw %ax,%bx jz __rtc_ok /* Set to fall back mode */ movb $RTC_BOOT_BYTE, %al outb %al, $0x70 inb $0x71, %al andb $0xfc, %al outb %al, $0x71 /* The byte is o.k. see where to go */ __rtc_ok: movb $RTC_BOOT_BYTE, %al outb %al, $0x70 inb $0x71, %al /* Transfer the boot bit from bit 0 to bit 1. * And clear bit 0 so that unless we say it works we * fallback to the other bios image immediately. */ movb %al, %bl andb $0xfc, %al andb $1, %bl shlb %bl orb %bl, %al outb %al, $0x71 testb $(1<<1), %al jnz __normal_image
