FILO 0.4
by SONE Takeshi
I just released FILO 0.4.
http://te.to/~ts1/filo/
It can boot distro CDs if you give a proper command line.
SuSE 8.2 LiveEval CD worked without a glitch, I enjoyed the
KDE desktop, OpenOffice, etc, from the CD on an EPIA booted
from LinuxBIOS.
Also added support for booting from BIOS flash, to boot an
alternative bootloader like Etherboot.
PCI support in IDE driver is also added (or recovered), but
the native PCI mode is not fully tested.
I tried to configure EPIA (V1) code to use native mode,
and the ports read something not 0xff, but the drive doesn't
respond to soft reset.
I don't know the bug is in FILO, LinuxBIOS, or the hardware.
I'll work on config file support next time.
Version 0.4 ts1 2003-10-15
* Support for ATAPI CD-ROM.
* ISO-9660 filesystem is taken from a GRUB patch by
Leonid Lisovskiy <lly(a)pisem.net>. The filesystem code was originally
written by Kousuke Takai <tak(a)kmc.gr.jp> for GRUB/98 project.
* Support for mounting boot disk image of El Torito bootable CD-ROM.
("hdc1" means the boot disk image of the CD-ROM at hdc.)
* Support for memory as device, raw device as image, and
user-specifiable device offset and length.
(eg. boot: mem@0xfffd0000,0x10000)
* PCI support in IDE driver. Now it by default uses PCI enumeration
to find the PCI IDE controller, and can use native PCI mode
if the controller is configured to this mode by BIOS.
To disable this, turn off SUPPORT_PCI.
* Fixed Linux loader to boot RedHat 9 kernel properly.

NXTV's current linuxbios patch
by Dave Ashley
I did a clean cvs checkout of freebios, then updated to 2003/7/5, and
did a diff between what's in our cvs and that, and this is the result.
It appears to be everything I touched. I got rid of all the CVS tree
differences.
Hope this is useful...I'm including a uuencoded gzip file. Sort of
dating myself here...

Re: IDE on s2885 and LinuxBIOS -- FILO
by YhLu
Ron,
I have checked pci.c in fifo. It need to be changes as follow.
It seems otherwise it can not scan the peer root bus.
Maybe someone need to make it can handle peer root bus refer to the code in
Linux kernel or Etherboot.
Regards
YH.
void pci_init(void)
{
/* Count devices */
dev_list = 0;
debug("Scanning PCI: ");
pci_scan_bus(0);
pci_scan_bus(1); // For Tyan s2880,s2881,s2882,s2885,s4880
// pci_scan_bus(3); //For Tyan s2885
debug("found %d devices\n", n_devs);
/* Make the list */
dev_list = malloc(n_devs * sizeof(struct pci_dev));
n_devs = 0;
pci_scan_bus(0);
pci_scan_bus(1); // For Tyan s2880,s2881,s2882,s2885,s4880

How to use Filo as a payload ?
by Peter Fox
I'm trying to get the STPC Elite development board to use
linuxbios with Filo, but after elfboot announces itself
the board reboots:
----------------------
.....
Welcome to elfboot, the open sourced starter.
January 2002, Eric Biederman.
Version 1.2
LinuxBIOS-1.0.0 Thu Nov 6 16:13:37 GMT 2003 starting...
Copying LinuxBIOS to ram.
....
------------------------
My config file looks like this:
target /home/fox/build/freebios1/stpc
mainboard stpc/elite
biosbase 0xffff0000
option CONFIG_COMPRESS=0
option SERIAL_CONSOLE=1
option TTYS0_BAUD=38400
option DEFAULT_CONSOLE_LOGLEVEL=9
option DEBUG=1
# option ROM_IMAGE_SIZE=131072
option ROM_SIZE=131072
option USE_ELF_BOOT=1
option PAYLOAD_SIZE=65536
payload /home/fox/build/filo-0.4/filo.elf
Any ideas as to what I've missed ?

IDEA: Linux kernel and pcbios compatibility...
by ebiederman＠lnxi.com
Brainstorming earlier today I think I have found a way to use
an linux kernel for the boot loader and to implement pcbios
compatibility without too much cost. The idea is to use
a uclinux kernel. And implement a ``user space'' aplication
that is a user space shim that makes kernel calls.
There are a few nasty details to work out like how to handle
services that are expected to work in vm86 mode. But I'm
not certain I care.
Other thoughts?
After I come back from my christmas vacation I am going to have to try
it and see how will it will actually work.

ide emulation based on network block device for arbitrary OSes?
by Adam Megacz
I've heard that you can use LinuxBIOS to bootload other operating
systems (like Windows, etc). Is it possible for LinuxBIOS to boot the
device and install a block of code in memory that handles BIOS disk
requests using some sort of network block device protocol?
Failing this, does anybody know of a cheap hardware device that would
do the same thing?
Thanks.

The power-up reset address for the Geode is FFFFFFF0h, you can't change
that.
Your only strapping options are:
(1) Enable either an 8 bit or 16 bit boot ROM access
(2) Enable either a LPC or ISA boot ROM access.

Re: Flash mapped to lower address?
by Devi Priya
Hi,
>From the AMD data sheet:
The Core Logic module positively decodes memory
addresses 000F0000h-000FFFFFh (64 KB) and
FFFC0000h-FFFFFFFFh (256 KB) at reset. These memory
cycles cause the Core Logic module to claim the cycle, and
generate an ISA bus memory cycle with ROMCS#
asserted. The Core Logic module can also be configured to
respond to memory addresses FF000000h-FFFFFFFFh
(16 MB) and 000E0000h-000FFFFFh (128 KB).
8- or 16-bit wide ROM is supported. BOOT16 strap determines
the width after reset. MCR[14,3] (Offset 34h) in the
General Configuration Block allows program control of the width.
Flash ROM is supported in the Core Logic module by
enabling the ROMCS# signal on write accesses to the
ROM region. Normally only read cycles are passed to the
ISA bus, and the ROMCS# signal is suppressed for write
cycles. When the ROM Write Enable bit (F0 Index 52h[1])
is set, a write access to the ROM address region causes a
write cycle to occur with MEMW#,WR# and ROMCS#
asserted.
The Boot Flash supported by the SC1200/SC1201 can be
up to 16 MB. It is supported with the ROMCS# signal.
As the corelogic module positively decodes the memory
addresses 000F0000h-000FFFFFh (64 KB) and
FFFC0000h-FFFFFFFFh (256 KB) at reset, I can have my Flash memory mapped to
the lower address. Is it?
