{{Status|

|CPU_status = OK
|CPU_comments = Geode GX1, Pentium 1 like, MMX support, no MTRR.
|CPU_L1_status = OK
|CPU_L1_comments = 16kiB unified cache (12kiB when X11 is running).
|CPU_L2_status = N/A
|CPU_L2_comments = This CPU does not support L2 cache.
|CPU_L3_status = N/A
|CPU_multiple_status = N/A
|CPU_multicore_status = N/A
|CPU_virt_status = N/A

|RAM_EDO_status = N/A
|RAM_SDRAM_status = OK
|RAM_SDRAM_comments = Tested with 64MiB and 128MiB modules at 100MHz (CPU core clock / 3).
|RAM_SODIMM_status = N/A
|RAM_DDR_status = N/A
|RAM_DDR2_status = N/A
|RAM_DDR3_status = N/A
|RAM_dualchannel_status = N/A

|IDE_status = OK
|IDE_25_status = N/A
|IDE_CF_status = OK
|CDROM_DVD_status = Untested

|SATA_status = N/A
|USB_status = OK
|Onboard_VGA_status = OK
|Onboard_VGA_comments = VGA support in coreboot works fine (e.g. for displaying a boot logo), for console/X11 you need a special kernel console and Xorg driver.
|Onboard_ethernet_status = OK
|Onboard_audio_status = OK
|Onboard_audio_comments = Tested with a special realtime SMI polling (no regular IRQs from the audio hardware) and Kahlua ALSA driver.
|Onboard_modem_status = N/A
|Onboard_firewire_status = N/A
|Smartcard_status = N/A
|Onboard_CF_status = OK
|Onboard_PCMCIA_status = N/A

|ISA_cards_status = OK
|ISA_cards_comments = Tested with backplane IP-6S.
|AMR_cards_status = N/A
|PCI_cards_status = OK
|PCI_cards_comments = Tested with backplane IP-6S.
|AGP_cards_status = N/A
|PCIE_x1_status = N/A
|PCIE_x2_status = N/A
|PCIE_x4_status = N/A

|Game_port_status = N/A
|IR_status = N/A
|Speaker_status = OK
|DiskOnChip_status = N/A

|Sensors_status = N/A
|Sensors_comments = This CPU does not need a fan.
|Watchdog_status = OK
|CAN_bus_status = N/A
|CPUfreq_status = OK
|CPUfreq_comments = Frequency scaling on this CPU is useless. Stop clock on HLT saves more power (enabled by Linux as default).
|Powersave_status = WIP
|Powersave_comments = Hardware supports dozens of such features, but someone must write the software to control them.
|ACPI_status = N/A

|Reboot_status = OK
|Reboot_comments = Linux supports this chipset to force a hard reset.
|Poweroff_status = OK
|LEDs_status = N/A
|HPET_status = N/A

|WakeOnModem_status = N/A
|WakeOnLAN_status = N/A
|WakeOnKeyboard_status = N/A
|WakeOnMouse_status = N/A
|Flashrom_status = OK
|Flashrom_comments = Works fine, both with coreboot and with the proprietary BIOS.

== Building FILO ==

[[FILO]] config for IEI JUKI-511P (boot from CF):

 USE_GRUB = 0
 AUTOBOOT_FILE = "hdd1:/boot/bzImage initrd=hdd1:/boot/initrd.gz clocksource=pit video=gx1fb:monitor:800x600@60,mode:800x600-8@60,crt:1 ide=nodma ide-delay=2 quiet"
 AUTOBOOT_DELAY = 0
 IDE_DISK = 1
 SERIAL_CONSOLE = 1
 SERIAL_IOBASE = 0x3f8
 # SERIAL_SPEED = 115200
 FSYS_EXT2FS = 1
 LINUX_LOADER = 1
 # 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 [http://lkml.org/lkml/2006/11/24/47]).
