Building filo

Maybe you will find our FILO config for DK8-HTX helpful:

1. !!! NOTE !!!
2. Do NOT add spaces or comments at the end of option lines.
3. It confuses some versions of make.

1. Use grub instead of autoboot?

USE_GRUB = 0

1. Image filename for automatic boot and optional command line parameter

AUTOBOOT_FILE = "hda1:/boot/bzImage syscrtc=/dev/hda1 initrd=hda1:/boot/image.minix.gz clocksource=pit video=gx1fb:monitor:800x600@60,mode:800x600-8@60,crt:1 ide=nodma ide-delay=2 hdb=none ide1=noprobe"

1. Time in second before booting AUTOBOOT_FILE

AUTOBOOT_DELAY = 1

1. Driver for hard disk, CompactFlash, and CD-ROM on IDE bus

IDE_DISK = 1

1. Add a short delay when polling status registers
2. (required on some broken SATA controllers)
3. NOTE: Slows down access significantly, so disable
4. whenever possible.

IDE_DISK_POLL_DELAY = 0

1. Serial console

SERIAL_CONSOLE = 1 SERIAL_IOBASE = 0x3f8

1. if SERIAL_SPEED is commented out, the speed will not be changed.
2. SERIAL_SPEED = 115200

1. Filesystems

FSYS_EXT2FS = 1

1. i386 options

1. Loader for standard Linux kernel image, a.k.a. /vmlinuz

LINUX_LOADER = 1

1. Boot FILO from Multiboot loader (eg. GRUB)
2. MULTIBOOT_IMAGE = 1

Building coreboot

$ cd targets
$ ./buildtarget iei/juki-511p
$ cd iei/juki-511p/juki-511p
$ LANG=C make

The LANG=C is only for those users that uses a localised system.

Using the hardware with a current kernel

The current 2.6.23 kernel does not know the CS5530 interrupt router. So it is impossible to let the kernel itself setup PCI's interrupt routing. Even if you provide the kernel with a valid interrupt routing table (PIRQ). No interrupts will work as the interrupt routing registers are still left at their reset values. The small patch below solves this issue (it was rejected in mainline as it breaks various standard BIOS based Geode systems, as they were shipped with broken PIRQ tables [1]).
