There is something odd going on with eepro-100
by Ronald G Minnich 10 Oct '02

10 Oct '02

Here is the scenario. This is a pre-release etherboot from Eric that has worked well on a number of platforms. The version is 5.1.2rc4.eb5. I take two identical advantech PCM-5283-2 systems, and put in a linuxbios flash that has worked fine for many months on a PCM-5823-1. The Etherboot I have built will boot preferentially from Compact Flash, loading a kernel and initrd which uses eepro100 to contact a server. If no flash is found, then it does a boot over Ethernet. System A System B CF boot Linux Works Works No CF, boot net Works Fails; sends DHCP but never sees reply. Packet is visible on network and dhcpd responds So, we have an interface which seems to work, and works on linux. It's basically the same board. etherboot correctly reads the MAC address from ROM. dhcpd sees packets from etherboot in both cases and responds. But System B never sees the reply ... this is really very odd. Here is the best part of all. An older flash, running etherboot 5.0.6, System B works fine. Yikes! I have no idea what relationship this has, if any, to the Smartcore problem I have been having, but it is at least pretty suspicious. The symptoms are almost identical. Anyway, I'm going to stick with CF for now but wanted to let the community know what was up. ron

Ram problem
by steven james 10 Oct '02

10 Oct '02

Greetings, I'm trying to get ram working on an e7500 MCH. It seems to be actually initting, but when I run ramtest it, I consistantly see a single bit toggled when reading back such as: 00024ab4:00024a94 00024abc:00024a9c 00024ad4:00024af4 00024adc:00024afc 00024af4:00024ad4 00024afc:00024adc 00024b14:00024b34 00024b1c:00024b3c 00024b34:00024b14 00024b3c:00024b1c 00024b54:00024b74 00024b5c:00024b7c 00024b74:00024b54 00024b7c:00024b5c 00024b94:00024bb4 00024b9c:00024bbc 00024bb4:00024b94 00024bbc:00024b9c 00024bd4:00024bf4 00024bdc:00024bfc Other times, I see that the second read (in order to display the bad value) actually reads successfully such as 000127a8:000127a8 Does anyone have any ideas what might cause that?

LinuxBios support for Via Mini-ITX motherboard
by Pierre-Yves Kerembellec 10 Oct '02

10 Oct '02

Hi all, I'm pretty sure this question has already been asked a thousand times, but I'd just like to know the status of the LinuxBios support on the VIA Mini-ITX motherboards (typically C3-based). I've seen things like mainboard/via/epia, src/northbridge/via/vt8601, src/southbridge/via/vt8231 or superio/via/vt8231 in the source tree but I don't know the exact status of the port ... the status on the web page does not state anything else ... Did anyone successfully used LinuxBios on the Eden platform ? Many thanks, Pierre-Yves

PIRQ checksum drama
by John Usher (Maptek) 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.

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. There is currently an > effort to boot BSD and also another to boot Win32 (probably XP). > Architectures include x86 and Alpha. IA64 is also in the works. 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 08 Oct '02

08 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
