[LinuxBIOS] [PATCH] Tyan S1846: Device tree fixes
by Uwe Hermann 03 Jun '07

03 Jun '07

The static device tree of the Tyan S1846 was, um... totally bogus. I'm using the ide0_enble/ide1_enable variables now to enable IDE. Hm, what happens if those variables are not set at all in a Confib.lb file of some mainboard? Do they default to zero?

[LinuxBIOS] which motherboard would be the better choice
by Mike Dilworth 03 Jun '07

03 Jun '07

hi all I am soon to buy a new motherboard and I have narrowed my choice down to 2. I am very interested in the LinuxBios project and am eager to "have a go". My question is whihc of these two motherbords would be better to use for LinuxBios: MS-7327 K9AGM2-FIH http://global.msi.com.tw/index.php?func=proddesc&maincat_no=1&cat2_no=&cat3… or the Abit AN-M2HD http://www.abit.com.tw/page/uk/motherboard/motherboard_detail.php?pMODEL_NA… as you can tell I need the HDMI feature. Other information: On both I will use the AMD Athlon X2 3800+ AM2 CPU MS-7327 uses AMI BIOS AMD 690G Northbridge and SB600 Southbridge integrated ATi Radeon X1250 videocard Realtek High Definition Audio Driver ATI System Drivers for RS480/RS482/RC410/SB600 AMD HDMI Audio Drivers Realtek 10/100 LAN Drivers ATI SB600 IDE RAID Driver Realtek Gigabit Ethernet Drivers from the photos it looks like this uses ??? its nt clear DIP BIOS??? Abit AN-M2HD NVIDIA® GeForce®7050PV/nForce 630a from the pictures i think this uses a PLCC: Plastic Leaded Chip Carrier this is about all i have to go on. Any pointers would be great. tia mike

Hi, Here's a one patch for IEI JUKI-511P and IEI ROCKY-512 half-size boards. This boards are little difference, that's why it has one patch. Linux with patchs from Juergen Beisert (http://www.linuxbios.org/pipermail/linuxbios/2007-May/020932.html) boots and work fine(ide, usb, ethernet, serial, keyboard and sound work normally). Problems: Filo load bzImage only from ide0. Video don't work, no any monitor output. JUKI-511P – PCISA half–size board: Specification: CPU: Geode GX1 300Mhz System Chipset: cs5530 SuperIO: Winbond w83977f-a Ethernet: rtl8100B Memory: one DIMM AC97: AD1881 ROCKY-512 – ISA half–size board: Specification: CPU: Geode GX1 300Mhz System Chipset: cs5530 SuperIO: Winbond w83977f-a Ethernet: rtl8100B Memory: 64MB on board and one DIMM AC97: no sound chip Here's also dmesg output. -- Nikolay

[LinuxBIOS] [PATCH] v3: Kconfig payload options and README improvements
by Uwe Hermann 03 Jun '07

03 Jun '07

Hi, here's a patch for v3 which reworks the payload selection in 'make menuconfig'. After the patch there are two simple options you can use: - Payload file You specify a path and filename for the payload. Default: payload.elf in the current directory. _How_ you create this payload does not matter; manual building, using a pre-built image from somewhere, using buildrom or lbdistro to create one etc. etc. - No payload This will create an "empty" image without any payload. You can later add a payload from the command line using the 'lar' utility. Something like 'lar add payload.elf linuxbios.rom' will add it... This is useful for multiple purposes: - Other "payload-projects" such as GNUFI or Open Firmware etc. can use LinuxBIOS as low-level bootstrap and incorporate LinuxBIOS in their own build process. They use the "empty" LinuxBIOS image as a base and use 'lar' to insert their own GNUFI / OFW / whatever image. - Linux distributions can ship 'linuxbios' packages which come with /usr/bin/lar and "empty" pre-built images for all supported mainboards somewhere in /usr/share, e.g. /usr/share/linuxbios/images/lb_empty_asus_a8n_e.rom /usr/share/linuxbios/images/lb_empty_tyan_s2882.rom /usr/share/linuxbios/images/lb_empty_gigabyte_ga_6bxc_256k.rom /usr/share/linuxbios/images/lb_empty_gigabyte_ga_6bxc_512k.rom etc. The user can then use those pre-built images and the 'lar' tool to insert any desired payload into the "final" image before flashing it. Heck, the distributions could even ship default payloads in /usr/share/linuxbios/payloads. We definately need some more discussion on the payload handling, but I think this patch is a good start. This system is flexible enough to manage any use case you can imagine, IMO. I documented the proposed procedure in the README in the patch, comments welcome. Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org
