[LinuxBIOS] A8N5X port
by Robert Millan
This patch includes config files for the asus/a8n5x port. It is the same as
asus/a8n_e with a different pnp layout, so I used #include's whenever possible.
System boots and is usable with usb keyboard.
works:
- serial port
- vga (old pci card)
- memtest86+ succeeds, but only with Rudolf's patch for unbuffered dimms
in K8. Otherwise you get spurious memory corruption.
- ide disk
- usb
doesn't:
- ps/2 keyboard
- onboard ethernet
- vga pci-e card (??)
- any other pci card I tried
wasn't tested:
- sata
- game port
- onboard audio (not supported by alsa anyway)
- ps/2 mouse

LZMA magic number
by Myles Watson
Is there a magic number for LZMA? Should there be?
I accidentally used an uncompressed payload with v2 when it expected a
compressed payload, and it gave me the message:
Decoder scratchpad too small!!
Decoding error = 1
I think it would be nicer to have an error like:
Payload not compressed with lzma!

flashrom verify fails, CK804, MCP55
by Tiago Marques
On two boards, one MCP55 based and another CK804, if I flash the
proprietary BIOS with: flasrom -wv bios.bin
Verification fails and if I try to boot, it doesn't. Have to flash the
BIOS in another board based on K8T890 that I have. In that one all
works fine, with both BIOS chips I have - one winbond and a PMC.
Haven't tried flashing coreboot due to lack of support.
Since the chipsets are support, this isn't supposed to happen, right?
Best regards,
Tiago Marques

[LinuxBIOS] flashrom support for AMD Geode CS5536
by Lane Brooks
Attached is a patch that enables AMD Geode CS5536 chipset support. I
have tested it successfully on a MSM800 board from digital logic. It
does, however, have a few issues that I would like some feedback on.
In my discussions with Marc Jones, Geode systems write protect the BIOS
via RCONFs (cache settings similar to MTRRs). Unlocking requires
changing MSR 0x1808 top byte to 0x22. Reading and writing to the msr,
however, requires instrucitons rdmsr/wrmsr, which are ring0 privileged
instructions so only the kernel can do the read/write. So my patch uses
the msr kernel module to access these instructions from user space using
the /dev/cpu/0/msr device.
My questions are:
- I do not think this is portable beyond linux. Is that an issue?
- My code assumes the msr kernel module is already loaded. Is there a
way to force a kernel module to load from the C code? My code does die
gracefully with a message reminding them to load the kernel module if
things fail.
- It seems like there should be a way to revert the msr back after
flashing is completed to put the bios back in write protect mode. Is
there a cleanup mechanism available? Something like disable_flash...
Thanks,
Lane Brooks

[LinuxBIOS] flashrom on ga 2761gxdk
by ron minnich
It now finds the part, and gets ready to program it, but exits
instantly without doing anything. I think this is the culprit:
void generic_spi_page_program(int block, uint8_t *buf, uint8_t *bios)
{
if (it8716f_flashport)
it8716f_spi_page_program(block, buf, bios);
}
i.e. the flashport is not set. So, before I dig too far into this, is
there some simple thing I should look at to get flashrom working on
this board?
Also, seems to me it's a pretty serious error if this can not be
determined, ... anyone mind if I add an error message? right now it
exits with no error, having done no work :-)
thanks

[PATCH] CN10K patch, FILO ide discover patch.
by Urbez Santana Roma
Note: for install this patch, you must download the last coreboot SVN,
and install first the patch posted by Corey Osgood, that includes
CN700/C7 and jetway mainboard.
The filo patch is for correct a problem with FILO when tries to find the
IDE disk, if more that
one IDE interface is on, and no all IDE's are in native Mode. The count
of compatibility
interfaces are wrong, and not finds the interface that is marked as a
IDE 0x0101 or SATA 0x0180
and not all are native, the search of the io base and control, are
wrong.
If this is not correct sorry :)))
If in VT8237R have SATA as an 0101 and the IDE too 0101 class, with this
patch, works, because
counts corectly the unique non native interface IDE, as the first.
NOTE1: in the epia-cn/Config.lb the IDE and SATA are enabled.
NOTE2: in epia-cn/auto.c the values of PCI_DEV(0,0x11,0) 0x50 and 0x51
are different, for have IDE and SATA enableds at function
enable_mainboard_devices
NOTE3: Here is a file base.c that haves a udelay with use of rtdsc
NOTE4: another function via_cn_fixup, fixes the use of PCI devices
access to the memory. Must be improved, and not use a fixed value.
NOTE5: have a change in cn700/raminit.c for configure in CN the memory.
NOTE6: vt8237r configures the SATA device as an IDE class 0x0101 must be
0x0180?????
