thanks for help
by zhu shi song 07 Oct '02

all is ok. thanks to andrew ip. btw, now i am using initrd_dyn to boot linux from DOC. I have checked the patch, the most recent patch is for kernel-2.4.18. I haven't got for kernel-2.4.19. Do you hear about it? or if I want to use 2.4.19, can you give me some suggestions? Also , i hope you can come over to shenzhen to play. we are very close. thanks zhu __________________________________________________ Do you Yahoo!?

usb root FS?
by Christopher Bergeron 07 Oct '02

07 Oct '02

Is it possible to use a DOC and a USB drive as the root filesystem? Has anyone ever attempted this? I understand that it not be fastest thing in the world, but it would be neat... Thoughts anyone? -CB

Low performance of the IDE on the SIS550
by Yves Godin 07 Oct '02

07 Oct '02

Hi everyone, I have a board based on the SIS550 (Vortex86 @167 MHz) and I wantd to setup a NFS file server that is capable to sustain 10 MBytes/s. But the problem is that the IDE interface seems very slow in writing. I patch my kernel (2.4.19) with the patch for the 5513 and now the controller is recognise as a ATA-100a but when I try to put the controller un UDMA mode mode 5, I got a message from hdparm that told that it is not supported. Anyway, with the UDMA mode 2 I should have the performance that I need. I look on header of the ide connector and the burst when writing seems to be quick anough but between each of these bursts I have a hole of 5-6 seconds. I test the speed with theses commands: time dd if=/dev/zero of=zero bs=1k count=100k -> WRITING -> 30 sec time dd if=zero of=/dev/null bs=1k count=100k -> READING -> 10 sec I try all configuration possible (hdparm) for the harddisk and 3 MB/s is the best result that I got. In PIO mode 4, I only got a 1.5 MB/s ! I performed theses tests on different architecture and I got the following results: SC520 PIO (ISA) -> 1.63 MB/s SC1210 PIO -> 4.54 MB/s -> I was unable to enable the DMA ???? P133 ATA-33 -> 5.50 MB/s PII-266 ATA-33 -> 17.83 MB/s PII-400 ATA-33 -> 20.54 MB/s C3-667 ATA-100 -> 23.05 MB/s Does anyone have an idea why: 1. I cannot enable the UDMA mode 5 ? 2. I only got 3 MBytes/s in writing ? Thanks ! Yves

I've just added andrew ip of cwlinux.com as a developer on linuxbios. Please welcome Andrew, he has been a real supporter and helped a lot with the SiS platforms, as well as running a company that sells linuxbios mainboards. Andrew, go ahead and apply those patches you posted in the last two days :-) ron

From: "Angelo Arifi" <angelo-arifi(a)cogeco.ca> To: <linuxbios(a)clustermatic.org> Subject: Mini-TX boards Date: Sat, 5 Oct 2002 12:47:27 -0400 hey guys, thats the future, mini-tx boards! i am going to be working on a project which will be a standalone dvd, divx, vcd, dvd, svcd, ogg, mp3, and more audio/video player. I will have to use a mini-tx for minimum noise, etc... but like i dont know whether you guys have worked on any mini-tx to support linuxbios. I was thinking about the same idea. ¿Did you have an idea how to begin the work? Ricardo Strauch --------------------------------- Do You Yahoo!?

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...

Does anybody know if linuxbios would also work on the supermicro p4dms-6gm.
