cannot initialize ide controller
by marcus wimmer 07 Oct '02

07 Oct '02

Hi there, I'm working on employing linuxbios for my emnbedded system. loading my kernel image from hda1 seems to be the best solution for my purposes. unfortunately I stick with some problems accessing the ide device for a whole while now. thus I don't seem to get around asking for help again and giving a description of my proceeding 'though I hate to bore busy people with details my target hardware: digitallogic smartcore-p5 SEN ROM MTD: 256k flash IDE device: 128MB disk on module what I did so far is: dos files converted: some time ago I reportet some building problems and nobody seemed to have stepped into that trap before. in the meantime the reason turned out to be several files containing dos like line terminators. (a greenhorns mistake, you may say ;) ) dos2unix helped. for a list of those files see addendum linker script changed: when running linuxbios first time on my target it got hung since some functions weren't found at the addresses where they're supposed to be. I solved this by setting the last alignment of every output section in ldscript.base to 32 my environment: both of the above difficulties may be specific for my particular environment: suse 7.3: gcc version 2.95.3 ln version 4.1 as version 2.11.90.0.29 I reported them anyway since someone might happen to have the same. config file changed to p5: many thanks to ron for the config file. was it meant to be for the p5? I changed all the 'p3's to 'p5's but left all the opions unchanged. (see addendum) what keeps me from proceeding now is: IDE initializing fails. when booting I recieve the message: (see addendum for full bootmessages) "I am now initializing the ide system Controller 0: detect FAILED (1) Initializing the main controller failed! Could not initialize driver..." which as far as I figured out means that the write and confirm read operation on the ide legacy port failed. The mentioned errormessage led me to try calling southbridge_fixup right after mainboard_fixup in hardwaremain.c (just like in the smartcore_p3 code) - without any effect. I wonder if a slightly different mainboard type could be responsible for that (smartcore-p5 SEN or SEV) or if the ide initialization might work for boards with compact flash but not for those with disk on module? Can someone help me to deal with that problem? regards, marc ADDENDUM: list of CRLF containing file in freebios: (additional ones may have been added since my last checkout) ./src/northbridge/acer/m1631/ipl.S ./src/northbridge/acer/m1631/ipl.h ./src/northbridge/intel/430tx/raminit.inc ./src/superio/SMC/fdc37c67x/setup_serial.inc ./src/mainboard/asus/cua/ipl.S ./src/mainboard/asus/cua/ipl.h ./src/mainboard/digitallogic/smartcore-p3/Config ./src/mainboard/digitallogic/smartcore-p5/Config ./util/config/l440gx.config ./util/config/l440bx-test12.config ./HOWTO/ALIM1631_M1535D adapted config file: This will make a target directory of ./smartcore-p5 target smartcore-p5 mainboard digitallogic/smartcore-p5 # Enable Serial Console for debugging option SERIAL_CONSOLE=1 option NO_KEYBOARD=1 option INBUF_COPY=1 option DEFAULT_CONSOLE_LOGLEVEL=7 option MAXIMUM_CONSOLE_LOGLEVEL=7 option DEBUG=1 option BOOT_IDE=1 dir /src/pc80/ide option USE_ELF_BOOT=1 option RAMTEST=1 option CONFIG_LINUXBIOS_ENABLE_IDE=1 option CONFIG_LINUXBIOS_LEGACY_IDE=1 payload /dev/null bootmessages: LinuxBIOS-1.0.0 Fri Oct 4 12:14:31 CEST 2002 starting...

Booting over Fast Ethernet
by Miguel A. Mota Jr. 05 Oct '02

05 Oct '02

Dear Mailing list members, I'm Miguel A. Mota Jr., Co-Founder and President of the Woodrow Wilson High School Science & Technology Club in Camden, New Jersey USA. With a few small grants from Lucent Technologies/Bell Labs, we have developed a parallel-processing Linux Cluster based on openMosix cluster technology. In a attempt to make this new technology more useful and efficient, I have integrated LAM-MPI and PVM into our cluster, giving it certain advantages of a Beowulf Cluster. The Nodes boot a custom CD-based mini-Linux distribution and configure themselves via DHCP, thus making them quite inexpensive and plug-n-play. I feel that this mixture of technologies makes cheap and yet efficient clusters. Our cluster is not that advanced in terms of hardware. Its not much, but its a modest start for a few minority teenagers in a urban city pushing for the movement of Open Source software. Its a star topology Fast Ethernet TCP switched cluster with 7 nodes. Here's a few key specs: - Server: AMD 750Mhz Duron w/390MB PC133 SD-RAM - Masternode AMD 750Mhz Duron w/128MB PC133 SD-RAM - Nodes 1&2: Intel 800MHz Celerons w/128MB PC133 SD-RAM - Nodes 3&4: AMD 650MHz Durons w/128MB PC133 SD-RAM - Nodes 5-7: Intel 450MHz Pentiums w/128MB PC133 SD-RAM We are currently trying to expand, but Lucent's loses in the stock market has affected our funding. So now we are trying to find companies willing to donate anything down to a 75Mhz PC, but no luck yet. While reading the paper, I came across an article on the clusters at Los Alamos. My understanding is that they booting their kernels from a Server. I was wondering if it could be possible to have our Nodes boot an ISO image off our Server in a similar fashion? This could allow us to bring the cost of Nodes down to $100 USD and utilize 486 DX PCs as well. I appreciate anyone's responses and thank you for your time. Miguel A. Mota Jr. Chaos325(a)Netzero.net

Hi, i read from a pdf that linuxbios supports just two motherboards . Is it true ? What r the boards available in INDIAN CHENNAI or BANGLORE or HYDERABAD or MUMBAI market support linuxbios ? I have rtlinux in a floppy . Could i use linuxbios and port it into a x86 board ? where should i start with ?? If so, plz tell me some clear steps ...

PCChips M758LMR+ works for me but...
by Todd E. Johnson 04 Oct '02

04 Oct '02

Hi again all, I am able to boot and get X up. It takes about 45 seconds, which is not bad, but it is a bit more than I was expecting. sshd takes up a bit of this time though. I have most everything else disabled. One of the largest problems is that none of the onboard USB ports work. Also, none of the PCI cards I am using appears to work as well (Which all of the devices work fine with the factory bios). Finally, I unfortunately rely heavily on ACPI to startup and shutdown the system. I have included a bit of output with this message, such as my config file, output from `lspci -vvv`, and the output from `dmesg`. Perhaps I did something wrong, or I'm setting my expectations a bit too high. I appreciate anyone's time and effort that the may put into this, and I thinking this pretty much rocks! (This would explain why I bought another motherboard and a few extra DOCs...) Any and all ideas are appreciated! Regards, Todd E. Johnson tejohnson(a)yahoo.com

Hmmm
by Todd E. Johnson 04 Oct '02

Did the following... `flash_on` `modprobe docprobe doc_config_location=0xfffc8000` Using configured DiskOnChip probe address 0xfffc8000 DiskOnChip Millennium found at address 0xFFFC8000 Flash chip found: Manufacturer ID: 98, Chip ID: E6 (Toshiba TC58V64AFT/DC) 1 flash chips found. Total DiskOnChip size: 8 MiB Gotta mailing list archives... I take it that I should rebuild the kernel w/ CONFIG_MTD_DOCPROBE_HIGH ? Regards, Todd E. Johnson tejohnson(a)yahoo.com
