Hi Ron, I've updated the patch slightly to add a routine to enable flash writes on the epia mainboard with out the need for the seperate setpci command. Mark On Friday 28 Feb 2003 22:13, Ronald G.

LinuxBIOS Laptop
by Bari Ari 28 Feb '03

28 Feb '03

Here's a nice candidate to build a LinuxBIOS laptop. http://www.xbitlabs.com/news/story.html?id=1046444411 The site is currently /.ed but the specs are: ECS announced recently its DeskNote i-Buddie A980 mobile desktop PC, the first ever mobile barebone computer. It features no display, no CPU, no RAM and no HDD, but only the case with keyboard and touchpad. The indisputable trump of the novelty is that you are free to install the most high-end and cutting-edge hardware, or you may buy not really expensive components that are enough for your needs. Here is the list of i-Buddie A980 technical peculiarities: * Supports Socket 478 Pentium 4 / Celeron processors with 400/533MHz FSB with 3.06GHz clock-speed and above; * SiS650 chipset with SiS962 I/O controller; * 1 DIMM slot for up to 1GB of PC2100 or PC2700 DDR SDRAM memory. * Integrated graphics core, ability to install NVIDIA GeForce4 Go420 mobile graphics card. * 2-channel ATA-100/66/33 integrated controller; * Includes an 8x DVD-ROM drive; * Free bay for 2.5 HDD; * 4 USB 2.0 ports; * FireWire (IEEE1394) port ; * IR port with transfer rate up to 115.2Kbit/s; * 10/100Mbit/s Ethernet adapter and connector; * Integrated 56K modem; * 6-channel audio solution and built-in speakers; * Size: 342mm (W) x 300mm (D) x 34mm(min)/50.5mm(max); * Weight: 1.8Kg. End-users have a lot of opportunities to expand and configure such computers, they even now can choose between 14 and 15 TFT panel, what should allow ECS customers to get the most cost-effective solutions possible. According to this French web-site, such barebones will be priced at $300. Not expensive, I believe, but remember that you will need to get a display, a microprocessor, a memory module and a hard disk drive to make it functional. Bari

flash_rom.c
by Mark Wilkinson 28 Feb '03

28 Feb '03

Hello I'm not sure who this should be addressed to, so appologies to the rest of the list. Briefly, I'm interested in running linuxBios on a via epia board, so I've gotten hold of a bios saviour ready to see how far I can get. After compiling up a rom image, and scanning the archives for how to burn the flash from linux, I compiled up the flash_rom program from the util directory. When running it with no image name (just so I could identify the flash chip of the bios saviour) I was greeted with a segmentation fault. To cut the story short, it seems that after scanning the pci bus in enable_flash_write() and not finding any of the devices in the enables (enable still set to 0) it still tries to call the 'doit' routine. I've included a patch that corrects the problem. Hope it's of use to someone. The second question I have (I think this is for Ron or Eric) is about the Config file under src/arch/i386/lib. I've notice that it has two copies of the 'object c_start.S' line. Is there a reason for this ? I've noticed that the NLBConfig.py script generates warnings about re-defining the object.

Hi, normally when a mainboard's specification say that has 2Mb of Flash ROM, are 2Mbits or Mbytes ..? Regards. Xavi.

Amptron 3787CLM - will donate hardware for support
by ziegast＠vix.com 26 Feb '03

26 Feb '03

Note: I'd normally use the linuxbios.org web page submission form, but the form is not working, and there is no contact info that looked readily available. The list isn't a bad place to find people willing to work on new hardware, so here goes... I found some cheap motherboards from Amptron that make an ideal terminal server or low-power workstation. It's the PIII-3787CLM+. You might recognize the motherboard if you bought one of those $199 Fry's/Walmart PCs recently. The motherboard + 733MHz Via C3 costs about $70 retail. It comes with just about everything you need for a desktop: AGP Video, AC97 sound, 10/100 Ethernet, and USB. All I need to do is add a floppy drive, some RAM, and then boot. Motherboard specs: http://www.amptron.com/html/MotherboardP3_M787CL+_frame.html I plan to use the motherboard on desktops (LTSP and/or diskless NFS-based RedHat 8.0) and some servers (add more RAM and maybe a a uDMA drive or two). I'd really like to just boot Linux off the BIOS to make boot times faster and have one less moving part to fail. If the BIOS supported USB boot drives, I'd just get a keychain drive and be done. The built-in Ethernet doesn't PXEboot, so LinuxBIOS looks like the only way to get rid of the floppy. I'd be glad to donate a montherboard ($70 retail value each) to anyone who can get one of them to boot to become either a LTSP client or a diskless Linux workstation (initrd root + NFS /usr) without the use of a floppy disk. I'll throw in a $20 256MB DIMM for fun. The label on the BIOS chip reads: "686 AMIBIOS (C)1999 BS46". The Amptron web page states it's 2MB "Flash". I don't know how this compares to DiskOnChip, but it's my preference not to have to buy/install DOC if I can avoid it. Reading the Sis630 LinuxBIOS HOWTO, I don't feel confident in my ability to get it to work on new unsupported hardware. If you think you can get it to work, drop me a line. If you can make a public HOWTO document for me and others to install LinuxBIOS on the board (without buying DiskOnChip), you can keep your parts. If it's not possible, let me know. I really like the hardware becasue it's an excellent, low-power (25W), cheap desktop platform. It could also be a part of dense low-bandwidth low-power server clusters.

Gentoo include an OpenMOSIX-patched kernel source tree, which is nice of them, so I only need to worry about the LinuxBIOS patches and hackery. I'm guessing that if I use the vendor-supplied BIOS flash utility, I don't need to muck around with MTD drivers, right? Looking at the HOWTOs, that method seems to be extremely icky at the moment, requiring kernel source edits. I don't mind getting a single floppy drive, and moving it between slaves for this step. -- -------------------------------------------------------------- from: Jonathan "Chromatix" Morton mail: chromi(a)chromatix.demon.co.uk website: http://www.chromatix.uklinux.net/ tagline: The key to knowledge is not to rely on people to teach you it.

help!!!who can explain the interface between linuxbios and linux.
by 王海明 25 Feb '03

25 Feb '03

dear all: I have developed a linuxbios debug system succefully.I introduced gdb stub into my system. In my system ,developers can debug linuxbios at source code level. I setup the stub at the beginning of the begin of the function of hardwaremain, the first c function.Now the system can excute the function of "step",'step into" "step out" ,"breakpoint"and so on. but the system has not been tested fully. I wonder if my design is usefull to others. by the way, I have several question.I will appreciate anyone's any idea! my question are as follows: 1. As we know, traditonal BIOS not only do some initialization work, but also put some data about the hardware in somewhere.BIOS even offer some routine such as intx( I know that In linux souce file "setup.s",int10, int13and int15 are used),but linuxbios doesn't offer. my question is: what is the mininal need of linux kernel's starting? what data does It need in detail? where does the data need to be placed in detail? what routine does linux kernel need for it's starting ? how does linuxbios offer these data and routines? 2. the second question is about PCI. I found that in linuxbios, some PCI initialization work is done.as we know ,in linux kernel, the same work was be done.Some linuxbios PCI initialization code is even the same with linux kernel. my question is: if the initialization in linuxbios is necessary? 3. my third question is about etherboot. I get a ide-patch of etherboot, and I succefully boot my system via IDE .I have read the code for a long time,but still have no idea about it. I found it seems does not do the same as setup.s,the kernel loader of traditional linux.who can explain it to me? I know there are some clever and experienced man in this site.I am very interested in this topic and admire all the man with good skills.I am looking forward to some help. best regards! yours HaimingWang
