Any UK DiskOnChip Retailers?
by Lee 18 Sep '02

18 Sep '02

Hi, My name is Lee and my machine has a ECS Elitegroup K7S5A motherboard. It has an AMD AthlonXP 1800+ processor and (apparently) a SiS735 chipset. It also has a 2Mb Flash EEPROM for the bios (AMIBIOS right now). Will the BIOS slot take a DoC or should I use regular replacement Flash EEPROM and is it possible to use an EEPROM/DoC with greater capacity than the current EEPROM? I'm also told I should use a Zero Insertion Force socket for the EEPROM. Do you know a UK supplier for the M-Systems DiskOnChip because I've tried Maplin Electronics' website with no avail and google UK has found little of any use. Also, where would you reccomend I get started with LinuxBIOS? Lee Causier, Signing off.

What's the absolute path to the absolute latest greatest memtest? I'm trying to see if my smartcore problem is a memory config problem. ron

util/mptable/mptable.c
by Ronald G Minnich 18 Sep '02

18 Sep '02

This now creates code that can be compiled into linuxbios. I have tested building with it but can't try running it just yet. I will test it later today but wanted to put it out for comments and corrections. The code is still ugly, I need to format it, but wanted to let people see it. It is adopted from a freebsd base. I ripped out getopt as getopt now varies too much: it has options on freebsd that appear not to exist on linux. ron

building MP tables
by Ronald G Minnich 17 Sep '02

17 Sep '02

Well I need (for the first time) to build an MP table. Actually just modify one. The ideal case is that somebody write a program like getpir that just dumps the current MP table. Anybody have one :-) ron

LInuxBIOS on Compaq ds10
by Kurt B Ferreira 17 Sep '02

17 Sep '02

All, Quick question here. I am going to be trying my luck at LinuxBIOS on a Compaq ds10L here and I was wondering if I require anything besides the code in the current CVS image. On a first look it seemed that some fo the source has not been checked in for the alpha, but that maybe my newness with the project. Thanks much Kurt

PCCHIPS M787CL+v3.0 support
by Andrew Ip 17 Sep '02

17 Sep '02

Hi, I just got a M787CL+ v3.0(http://www.pcchips.com.tw/M787cl+v30.html) which is as the same as m758lt+ with VIA C3 1GHZ. It works with m758lt+ config without any problem, and it costs only US$15 more than m758lt+. I think it is a very nice alternative to EPIA. -Andrew -- Andrew Ip Email: aip(a)cwlinux.com Tel: (852) 2542 2046 Fax: (852) 2542 2036 Mobile: (852) 9201 9866 Cwlinux Limited Unit 202B 2/F Lai Cheong Factory Building, 479-479A Castle Peak Road, Lai Chi Kok, Kowloon, Hong Kong(SAR), China.

I think I'd like to put a little advertisment for my consulting business on each side (just my mail address and a link to my web page). I have actually written most of the presentation in a more verbose format, so I think that could be a better thing to put on the web. I'll try to clean this up a bit and post a link to it. The presentation went rather well I think, I managed to stay within the allocated time and think I managed to talk about most things that I wanted to. But the presentation was a bit of a disappointment, only five people showed up, a casualty of this being a rather specialized conference (Real time and Embedded Computing Conference) and that I had the absolutely last slot of the day when most people had already left; most other presentations seemed to have about 10 attendants. I did get a presentation out of it though and it sounds as if I might do a presentation at a couple of academic computer societies for friends so this could be rather fun. /Christer -- "Just how much can I get away with and still go to heaven?"

I love this one: Less buggy <== Currently the Bios does some many things in order to support all OS, that the code is huge and still written in assembly language. I will say more debuggable than normal bios.

Hi again, I'm late as usual, but here are some slides that I'm planning to use for the presentation tomorrow. Any comments? Any glaring errors? http://zoo.weinigel.se/slides.pdf I'm actually a bit nervous, my spoken english is rather rusty and I haven't been talking in front of an audience in years... /Christer (off to sleep) -- "Just how much can I get away with and still go to heaven?"
