Re: Freebios1 STPC Elite development board changes attached
by Fathi BOUDRA 25 Feb '04

25 Feb '04

Hi, thanks for all, the compile works now. I used the redhat 7.1. with Debian stable (woody) it works also. Now i try to use the romimage with my stpc elite board but it hangs after: Call init Enabling com device: 04 iobase = 0x03f8 irq=4 after this some strange character ... On my stpc elite card, i have only 2 serial ports, no floppy, no parallel port. Maybe something goes wrong with this ... i try to use NO_KEYBOARD option set to 1 and MUST_ENABLE_FLOPPY option set to 0 but no change. if someone have an idea ..., now i'm looking into the sources.

Freebios1 STPC Elite development board changes attached
by Peter Fox 23 Feb '04

23 Feb '04

Please find attached my changes to support the STPC Elite processor, and the mainboard/elite build configuration for the STPC Elite development board. These changes are for freebios1. They are mostly copies of the consumer-II stuff by Steve M. Gehlbach, but modified to remove all the graphics stuff, as the Elite has no graphics controller, and to add initialisation for the GP clock etc. I've also put in the bit-bashing SPD code for the Elite, though I don't use it on the development mainboard. I can run Redhat 7.1 fine (serial console only) using filo as the payload. This is using the 20/01/2004 snapshot for other files. -- Peter Fox <peter.fox(a)aeroflex.com> Aeroflex Test Solutions Principal Design Engineer Stevenage Any opinions expressed above are http://www.aeroflex.com/ not necessarily those of Aeroflex.

Testing linuxbios

Hi ! I played a little building up few images of linuxbios but i need to know if there is a way of test these images via floppy boot to not need every time to flash ? Thanks, cristian

I am a little puzzled in steps of making/flashing/testing, I dont understand something at few points: First Q: So my config file, (i atempt to boot on 440bx plus Stefan's latest bk OpenBIOS) so i put it as elf payload, Is it correct ? --------------------///////////////----------------------------------------------------------> target l440bx mainboard intel/l440bx # Enable Serial Console for debugging # It will come up at 115200,8n1 option SERIAL_CONSOLE=1 option VIDEO_CONSOLE=1 # Enable MicroCode update and L2 Cache init for PII and PIII option UPDATE_MICROCODE=1 option CONFIGURE_L2_CACHE=1 # Use the internal VGA frame buffer device #option HAVE_FRAMEBUFFER=0 option USE_CACHE_RAM=0 option USE_GENERIC_ROM=1 option USE_ELF_BOOT=1 makedefine PHLASH_BASE_NAME=laci option CONFIG_UDELAY_TSC=1 option CONFIG_COMPRESS=0 payload /home/rezso/freebios/builtin.image ----------------////////--------------------------------------------------------------------------> I used todays sourceforge CVS pool.

Replacement for console level access on ALPHAs
by Andy Pearce 18 Feb '04

18 Feb '04

We currently run a set of systems that operator on DEC Alpha machines, these provide a console level access which we use to configure a machine remotely via the console port. Plans are afoot to migrate the systems running on the Alphas to PC (HP xw4100 machines), we will still however have the requirement to access and manage the machines when the main OS is down, select which kernel versions should be run etc. Based on what I have read about Linux Bios it seems it would be perfect for this task. Does anyone have any idea of the likelihood of the HP xw4100s motherboard being able to support LinuxBios. Many thanks Andy Pearce

RE: Use of compact flash
by Lombard, David N 17 Feb '04

17 Feb '04

Be aware, that there are some small "adapters" that allow you to plug your CF onto an IDE cable; PC-CARD-to-CF adapters; and USB (and some IDE) based devices that support CF and other memory devices. The latter two are hot-swap capable; AFAIK, the first type is not. I have both a PC-CARD-based unit (a SanDisk "CompactFlash(tm) PC Card Adapter") that I use in my laptop along with a USB-based built-in device (fits into a 3.5" drive slot of my desktop) that supports the gamut of memory devices. I've had the PC CARD unit much longer as it was supported in the 2.2 kernel. I've heard direct reports of people that have fried bits of their chipsets by just yanking a CF out of the IDE cable "adapter" type of connector while the system was powered. Bottom line, make sure you use know the operating characteristics of your CF connection technology. -- David N. Lombard My comments represent my opinions, not those of Intel Corporation.

I forgot to mention the very elegant solution to this problem. At some simple power of 2 the Opteron memory is hoisted above 4G. The overlapping mtrrs do not need to be implemented. This is something I would like to play with but I have not yet had the chance. The meaning of that FIXME is that we are currently misplacing a noticeable chunk of memory on Opteron machines with 4GB of RAM. Eric

Can I use Linux BIOS on a Intel Pentium IV Motherboard??? Is that possible for me to compile one such, if it is not available at present ??? -- Poonchezhian P. Email : pchez(a)mail.cyberneme.com
