PPC tree created
by Ronald G Minnich 21 Oct '02

21 Oct '02

we've got two people looking at PPC support. I've created the skeletal structure for the beginnings of PPC. For starters, I've created src/arch/ppc and src/cpu/g{2,3,4} trees. If those of you doing PPC want to get back to me with mainboard names etc. we can plug those in too. ron

SIS 620 - Specifications request
by Eddi 20 Oct '02

20 Oct '02

Hi, I'm new of this mailing list. I have an Acer Power SE equipped with a motherboard with SiS 620 chipset. Since I've seen that your project doesn't support this chipset, I'd like to use my mainboard to write a bit of support for this chip too. I've read in the archive that perhaps "ollie" can give me some information about this chipset and how to initialize it. Best Regards Eddi

VIA EPIA status
by Andrew Ip 20 Oct '02

20 Oct '02

Hi, Just checked in new code for VIA EPIA src/mainboard/via/epia/irq_tables.c src/mainboard/via/epia/Config src/mainboard/via/epia/do_ramtest.inc util/config/epia.config These checkins enable LinuxBIOS to boot 'till etherboot, but it has problem to see harddisk and network card. For those who want to debug/have fun, a sample config can be found at util/config/epia.config. To make flash writable, you need to run `set setpci -s 0:11.0 40.b=54` before running flash_rom. -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.

Sounds good to me. That's why I asked if they were ignorant questions :-) -dBarr. >As long as the keyword doesn't contain the separator it shouldn't matter. >KEYWORD SEPARATOR VALUE >KEYWORD is any number of any characters excluding ":" >SEPARATOR is the string ": " >VALUE is the remaining characters up to a CR or LF >And ":" IS the sensible separator IMO. >//Peter

Sorry about the freemail -- The uni, in their infinite wisdom, decided to take down the campus' mail system for all of fall break. Pardon me if these are a bit ignorant: 1) I'm assuming the name of the mainboard itself will be the status file name. Or will that only be contained in mainboard-revision? 2) Links: http>:<//www.linuxbios.org; Will this be a problem? >Here, based on input, is the mainboard status file format. >Comments welcome! >If I don't hear any more ideas I will put this out today or >monday. ># These are keyword-value pairs. ># a : separates the keyword from the value ># the value is arbitrary text delimited by newline. ># continuation, if needed, will be via the \ at the end of a line ># comments are indicated by a '#' as the first character. ># the keywords are case-INSENSITIVE ... >Links: >Mainboard-revision: ... -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup

e7500 and gas and undefined and ...
by Ronald G Minnich 18 Oct '02

18 Oct '02

OK, here is a fun one. secondary.inc moved to separate compilation as secondary.S It won't assemble: secondary.s: Assembler messages: secondary.s:87: Error: subtraction of two symbols in different sections `gdt_end' {*UND* section} - `gdt' {*UND* section} at file address 155 make: *** [secondary.o] Error 1 The problem code is: gdtaddr: .word gdt_end - gdt - 1 /* compute the table limit */ .long gdt /* we know the offset */ Now, I have to sign off -- kids and all that -- and I'm hoping some of you gas experts can puzzle this out. What should happen is that the gdtaddr in secondary.S will have pointers to the gdt defined in crt0.S. Obviously something needs fixing here so that the undefined references in secondary.S are properly set up so you have a gdt in secondary.S. One option is to include the gdt from the .inc file. That *UND* section is kind of suspicious -- Maybe another directive is needed? ron

Here, based on input, is the mainboard status file format. Comments welcome! If I don't hear any more ideas I will put this out today or monday. # These are keyword-value pairs. # a : separates the keyword from the value # the value is arbitrary text delimited by newline. # continuation, if needed, will be via the \ at the end of a line # comments are indicated by a '#' as the first character. # the keywords are case-INSENSITIVE owner: Ron Minnich email: rminnich(a)lanl.gov #status: One of unsupported, unstable, stable status: unstable explanation: flash-types: payload-types: # e.g. linux, plan 9, wince, etc. OS-types: # e.g. "Plan 9 interrupts don't work on this chipset" OS-issues: console-types: # vga is unsupported, unstable, or stable vga: # Last-known-good follows the internationl date standard: day/month/year last-known-good: 0/0/0000 Comments: Links: Mainboard-revision: # What other mainboards are like this one?
