PIRQ checksum drama
by John Usher (Maptek) 10 Oct '02

10 Oct '02

G'day all... I am currently having trouble with the irq_tables.c produced by getpir. I am receiving the following error from the linuxbios boot: Checking IRQ routing tables.../root/aug2002/lb/freebios/src/arch/i386/lib/pirq_routing.c: 24:check_pirq_routing_table() - irq_routing_table located at: 0x0000b0c0 /root/aug2002/lb/freebios/src/arch/i386/lib/pirq_routing.c: 31:check_pirq_routing_table() - checksum is: 0x26 but should be: 0x7a /root/aug2002/lb/freebios/src/arch/i386/lib/pirq_routing.c: 49:check_pirq_routing_table() - checksum error in irq routing table done. Copying IRQ routing tables to 0xf0000...done. As can be seen from irq_tables.c, the checksum internally is 0x26, and getpir did not report any errors when it downloaded the table. Does anyone have any ideas? John... irq_tables.c follows: /* This file was generated by getpir.c, do not modify!

LinuxBIOS instead of Dell BIOS
by Billy Mullins 09 Oct '02

09 Oct '02

Hi, I work with a couple small clusters of Dell PC's, and I'm wondering if someone would be able to give me an educated guess as to whether or not LinuxBIOS will work out of the box for these PC's. I've looked at the supported mb list, and they don't seem to be listed, but maybe... The machines are the Dell Optiplex Gx240, they use the standard Dell BIOS Release A02, and have the Intel 845 chipset. What are the factors that play into whether or not you can use LinuxBIOS out of the box(maybe that is in a faq somewhere)? For example, just the chipset, strange motherboard quirks, etc... Also, what would it take, and has anyone tried to get a Dell PC to run LinuxBIOS? Thanks much, Billy Mullins

[Fwd: Re: [PPCBoot-users] PPCboot vs ARMboot or Blob and a Merge with LinuxBIOS]

So your boot sequence is LinuxBIOS => Linux => LinuxBIOS => Target OS? Seems a bit overkill to me. Especially in systems where (flash) memory is tight it might be a PITA to have to reserve space for a Linux kernel just to initialize the hardware. > LinuxBIOS has booted; Linux, Plan9 and Win-CE.

The current version of PPCBoot boots Linux, VxWorks, QNX, and NetBSD. It comes with out-of-the-box configurations for 98 x PowerPC boards (MPC8xx, MPC824x, MPC8260, MPX7xx, MPC74xx, IBM 4xx), 3 x StrongARM boards, 2 x ARM7 and 3 x ARM9 systems. This includes a couple of commercial products like boards by esd, Gespac, Microsys, TQ, but also desktop systems like the AmigaOne or real-life products (from ISDN routers, Bluetooth LAN Access Points to bigger things like huge mobile cranes). Ports for ColdFire and XScale are in the works. x86 is being discussed. > For simple systems PPCboot looks like a great way to go. LinuxBIOS would > add support and config for more complex systems that include PCI, PCI > Express, Infiniband and Hypertransport. It seems you do not know much about PPCBoot. PPCBoot supports a LOT of devices, of course including PCI. But also plain flash, DOC, flash disk, Compact Flash, harddisk, CDROM, SCSI devices, even some USB. PPCBoot provides a very powerful method to store configuration parameters and command sequences. In most systems you do not need tools like ifconfig, route, etc. because PPCBoot can pass all required information to the Linux kernel's IP autoconfig mechanism. The environment is protected, and can be stored redundand so it is a very reliable mechanism. PPCBoot also provides powerful scripting capabilties; busybox' "hush" shell has been integrated, so you can write standard shell scripts or run conditional command sequences using "if...then...else...fi", "for...do...done", "while...do...done", "until...do...done", or using shortcuts like "cmd1 && cmd2" or "cmd1 || cmd2". A lot of complicated things like reliable software upgrade procedures with guaranteed fall-back to the old, working version can be implemented in PPCBoot with just a few lines of script. PPCBoot also provides many additional features that are less frequently required, but very handy when you need them, for example dial-in support (so you can attach a modem to the serial console for remote administration), password protection, extensive POST code, etc. etc.

LinuxBIOS in 512KB flash
by Hieu T. Tran 09 Oct '02

09 Oct '02

We're working to port LinuxBIOS to a via 133 platform with a 512KB boot flash. We believe that the flash is wired such that on reset, 0xFFFF0 is mapped to 0x7FFF0 on the flash, which is slightly below 512KB on the flash. We have been trying various config file settings (ROMTOP, ROMSIZE, PAYLOAD_SIZE) to position ROMTOP and reset_vector accordingly without much success. Simply getting a larger flash wont help since the board will only recognize the first 512KB. Has anyone solved this problem? -- HT htran(a)viosoft.com

It's also gaining popularity for x86 embedded applications. LinuxBIOS also includes support for Etherboot. LinuxBIOS currently boots x86 to Linux and Plan9. It's also being used to build a new 10TeraFLOP cluster at LANL. http://www.lanl.gov/worldview/news/releases/archive/02-106.shtml Bari

All, I would like to get my feet wet and build a cheap 3 node cluster to play with linux bios, beowulf, etc. Soo, if you were starting from scratch and wanted the motherboard that... - is cheap - has good linux bios documentation - has a good success rate ...which would you choose?
