re: Etherboot 5.2.4 + btext console + filo patch
by YhLu 27 Apr '04

27 Apr '04

To me filo is just like enhancement to Etherboot ide_disk.zelf. but it is more smart that it can understand file system and boot linux/initrd instead of elf. If we can put filo into Etherboot official tree, we can make use of the framework of Etherboot. For example in Etherboot you still can only produce filo.zelf, and it is less 32k now. I didn't enable the multiboot in filo of Etherboot yet.

There is enough appeal to the simplicity of FILO that we're not as interested (here anyway) in the etherboot integration. FILO is a small simple loader that does what it does well; Etherboot is a whole lot more complex. That does not mean I think merging it in is bad, but I also would like to see it maintain its seperate existence. ron

IBM/E325 problem fixed, other problems remain
by Li-Ta Lo 27 Apr '04

27 Apr '04

Hello, I fixed the problem of all device on bus 0. It was an undefined struct chip_control mainboard_ibm_e325_control, it is declared in chip.h but is not actually defined in mainboar.c. Ron forgot to change the name of the strucutre to ibm_e325 from arima_hdama. Now the questions, why didn't gcc complain about this ? If that line in chip.h is treated as "declaration" than missing the real definition in mainboard.c for the IBM/E325 before is an error. If that line in chip.h is a definition than the second definition in mainboard.c for all other mainboards is an error. Why does not gcc say anything ? Should I go back to school to learn C programming language again ? Ollie

Ron, Do you need to create contrib or payload dir to put such kind of patch. Because Etherboot group may not accept such kind of patch.

PVR with LinuxBIOS. What board is recommended? Some questions
by Jochen Roemling 27 Apr '04

27 Apr '04

Hi all, I'm trying to build up a PVR (Personal Video Recorder) using LinuxBIOS because of it's fast startup time and because I'm interested in playing around with this on-the-edge matter. I spent hours on the net trying to find a suitable motherboard. To be serious: I found not even one that seems to be supported by LinuxBIOS, supports everything I need and is still in the shops of the retailers or eBay. The Status page on linuxbios.org seems to contain mainly very small boards with only 2 or 3 PCI slots that are aimed towards cluster nodes. Those questions may all sound like newbee questions to you, but please reply at least yes or no, I would then commit a HOWTO if I get the whole stuff working: 1. I found out that LinuxBIOS supports VGA only for very few chipsets like the SiS630. If I would use a VGA card that comes with it's own BIOS (let's say some ATI radeon) and not using any on-board-VGA-device, would it work if the mainboard has a LinuxBIOS-supported chipset? My feelings say "yes", don't they? 2. I'm going to use the Hauppauge PVR 350 card that has a TV-out which - according to the net - is available to Linux as a frame buffer device, so X and the TV Applications should be able to use this. Does this mean I would be able to boot LinuxBIOS with serial console only and then start up XFree86 using this PVR 350 Framebuffer device? 3. Just to verify that I understood everything right: The Kernel that is burned into the DoC will be the kernel that runs the machine after bootup and it is possible to mount the root fs via NFS just like LTSP does? Or will the kernel on the DoC just to be used to initialize the hardware and then load another kernel via the net or from disk? Or do I have both possibilities? 4. Is it correct that kernel 2.4.19 is the latest one supported by LinuxBIOS? Should the patches be good for 2.4.26 also? What about 2.6? Maybe you can recommend some motherboards out of the box that are still available in the shops? They should support CPUs with about 1200 MHz, have at least 2 PCI slots for TV cards, another PCI slot for an AC97 soundcard with optical SP/DIF output (only if there is no such linux-supported connector on-board) and another PCI slot for a 3com network card with BootROM (not needed if the LinuxBIOS on the DoC is running the whole machine and can mount root via NFS or if the board can net-boot via the on-board NIC). Thanks in advance for your help which will be highly appreciated! Best regards Jochen

So it is there. For some reason it is not being called. A missing chip.h perhaps? My old copy of that code does: max = pci_scan_bus(&root->link[0], PCI_DEVFN(0x18, 0), 0xff, max); So it starts at device 0x18 (The first cpu) and works down. That is not happening so that code is not being called. I don't know why/how it is failing except possibly for fragility in the config tool. But I observe it is not.

EPIA-M startup times
by Dmitry Borisov 27 Apr '04

27 Apr '04

Guys, Just wanted to have your estimate about startup times for EPIA-M mobo. ATM it takes about 9 secs to go to payload. 7 secs to go to splash. Which seems to be really high values. Does anyone can say what it would be if everything is "perfect" ? How much time at minimum the BIOS can take assuming RAM, VGA and PCI initialized properly ? If the answer would be 4 secs in ideal case, I'll invest some time to tighten it up... If 9 secs is a minimum, then... Any suggestions ? Dmitry/
