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

just 2 boards supported by linuxbios
by Karthik Bala Guru 05 Oct '02

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 ... Xpecting ur help, karthik bala guru ________________________________________________________________________ Missed your favourite TV serial last night? Try the new, Yahoo!

PCChips M758LMR+ works for me but...
by Todd E. Johnson 05 Oct '02

05 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

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

I have a cs5530 chip that drives IDE.. and southbridge/nsc/cs5530/southbridge.c is used to enable the IDE. isn't this the same as rr2? what patch were you referring to when you told me I needed a patch to read C/H/S values correctly?

nonsense C/H/S values for CF (used in ide)
by Q-ha Park 04 Oct '02

04 Oct '02

I have a board with gx1, pc97317 and cs5530a with one ide slot. I've been booting linux with Phoenix bios so far with no problems, and I tried linuxBIOS to boot linux. but I noticed strange C/H/S values like "init_drive sectors_per_track=[768], num_heads=[768], num_cylinders=[768]". and it failed to boot. does anyone have similar problems like this? Phoenix bios sees the device and read the values correctly... thanks, Q

Hi all, I purchased what I believed to be 2 DOC Millennium chips from Tri-M, but the part number is: MD-2800-D08 Is this right?!? Because this is the `dmesg` output when I try to burn the ROM: Possible DiskOnChip with unknown ChipID 00 found at 0xc8000 Possible DiskOnChip with unknown ChipID 35 found at 0xca000 Possible DiskOnChip with unknown ChipID FF found at 0xcc000 Possible DiskOnChip with unknown ChipID FF found at 0xce000 Possible DiskOnChip with unknown ChipID FF found at 0xd0000 Possible DiskOnChip with unknown ChipID FF found at 0xd2000 Possible DiskOnChip with unknown ChipID FF found at 0xd4000 Possible DiskOnChip with unknown ChipID FF found at 0xd6000 Possible DiskOnChip with unknown ChipID F6 found at 0xd8000 Possible DiskOnChip with unknown ChipID E8 found at 0xda000 Possible DiskOnChip with unknown ChipID 97 found at 0xdc000 Possible DiskOnChip with unknown ChipID 63 found at 0xde000 Possible DiskOnChip with unknown ChipID 00 found at 0xe0000 Possible DiskOnChip with unknown ChipID 00 found at 0xe2000 Possible DiskOnChip with unknown ChipID 00 found at 0xe4000 Possible DiskOnChip with unknown ChipID 00 found at 0xe6000 Possible DiskOnChip with unknown ChipID 00 found at 0xe8000 Possible DiskOnChip with unknown ChipID 00 found at 0xea000 Possible DiskOnChip with unknown ChipID 00 found at 0xec000 Possible DiskOnChip with unknown ChipID 00 found at 0xee000 No recognised DiskOnChip devices found root@grandamp:/usr/local/src/linuxbios/buildrom/m758lmr+# Regards, Todd E.

athlon board choice
by David Thomas 03 Oct '02

03 Oct '02

I've been researching a board for cluster computing. This is my wishlist 1. Dual Athlon 2. At least 2GB RAM capactity. DDR or other high-speed is critical. 3. midrange -- not dell or ibm for cost reasons 4. Integrated video and 10/100 NIC, dual NIC a plus, SCSI not necessary 5. 1U or 2U ATX form factor 6. Lots of hardware monitoring. ASIC/IPMI a must. 7. (of course) will run LinuxBIOS I've tetatively settled on a Tyan Thunder K7 S2462 and I've had reasonable experiences with the vendor in the past. For bios it says it's got a 4MB flash chip and supports DMI 2.0. I'm new to LinuxBIOS so comments are appreciated. There's a page at : http://www.tyan.com/products/html/thunderk7.html and manual at ftp://ftp.tyan.com/manuals/thunder/m_s2462_100.pdf Thx Dave

RE: Images and ZIF DIP
by Todd E. Johnson 02 Oct '02

02 Oct '02

Hi Ollie, Why do you think I wanted to gauge how fast it would boot ;) ? Isn't research fun? Actually Hui-Fen helped me out with the SiS 900 NIC driver for a BioStar M5SAF. It was some issue with the PHY. It worked great, but alas, it is time to upgrade! Most people would perhaps consider me insane... See what working for the Government can do to a guy? This is a hobby to keep me sane... If you find it interesting, you may want to check out http://www.dashpc.com/ Regards, Todd E.
