RE: [LinuxBIOS] Intel E7501 Northbridge head-scratching
by YhLu
What i did about Intel LinuxBIOS support
1. change ICH5 to ICH5R in v1.
2. move E7501 and ICH5R from V1 and V2.
For SB, documentation should be enough.
For NB, I guess there is some undocumented info, and you may talk to intel
directly or hack it out.

No.
Acctually you should select that according to your applicance....
Maybe change to use AMD or other platform, or even PowerPC.

[LinuxBIOS] How is 'arch' working for you?
by Ronald G. Minnich
Are folks getting along with 'arch' ok? Are you able to download as
needed? How does it compare to CVS? Is there a different SCM you would
like to see used?
thanks

It should be working. But I wonder some AMD check in about MTRR or CPU
initialization would break it.

why still waste time on Intel platform? They will not support LinuxBIOS,
because they have EFI....

[LinuxBIOS] Intel E7501 Northbridge head-scratching
by Steve Magnani
Hi,
Does anyone (Steven James? yhlu?) know what registers 0x14, 0xD8, and 0xF4
in the E7501's D0:F0 PCI configuration space are for? I know that 0x80 and
0x88 are undocumented, but I didn't see anything in the code
(northbridge/intel/e7501/raminit.c) that said these others were
undocumented. Unfortunately, they seem to be; at least, I can't find any
mention of them in any of the Intel documentation I have.
Also, if I am reading the code correctly, the last entry in
register_values[] will update D2:F0:0x50. That register is also undocumented.
Any help would be much appreciated...
Thanks,
Steve Magnani

Re: [LinuxBIOS] Is any notebook with Nvidia NForce4 or Ck804?
by YhLu
ATI Xpress 200M in HP ZV6000 support pci-e.
I wonder why there is no Nvidia CK804M for NB. Too hot?
First NB support LinuxBIOS?

[LinuxBIOS] CK804 hard_reset
by Stephen.Kimball＠bench.com
One of the hard_reset() functions are wrong. The two files don't agree:
src/mainboard/tyan/s2895/auto.c
src/southbridge/nvidia/ck804/ck804_reset.c
I think auto.c is correct, but I'd suggest changing it to:
static void hard_reset(void)
{
set_bios_reset();
pci_write_config32(PCI_DEV(1, CK804_DEVN_BASE + 0x1, 0), 0xe8, 0x0);
/* hard reset */
outb(0x0a, 0x0cf9);
outb(0x0e, 0x0cf9);
L1: goto L1; /* loop till reset */
}

We have the CRB working. We'd like to work with you and nVidia to
improve what you have released.

You could talk to Nvidia to see if I can release support code for their
CRB....
It seems that you have spend lot of time on it.
