If you want to ask a question please ask it publicly. As for the HPA. If my memory serves me correctly you do not need any special permissions to access it, just a special command or two to the drive. But I may be thinking of something else. Eric

Two possible boards...
by Nathanael Noblet 04 Nov '02

04 Nov '02

Hello, I'm interested in working on a couple boards. One is a sis530 and the other an intel 430VX. I have the cvs code checked out today. What I am really unsure of is how to proceed. I have a data/spec sheet on the sis530 (and its onboard 3d video card). But I look at the source tree and there are SO many empty directories and such. Is there some kind of how-to on where to start to get a board supported? I'm really at a loss. What code needs to be written so that a particular board works? I realize that that is a pretty open ended question. I just don't know where to start in a project like this. -- Nathanael Noblet Gnat Solutions 4604 Monterey Ave NW Calgary, AB T3B 5K4 T/F 403.288.5360 C 403.809.5368 http://www.gnat.ca/

m758lmr+ motherboard
by James Alton 03 Nov '02

03 Nov '02

Hello, I'm using the pcchips m758lmr+ motherboard. I have browsed through the CVS code, and I see that it loads up support for the SiS630s chipset. Also, on the board though, there is a IT8705F (from ITE) which acts as a superio and thermal/voltage stats. (The IT8705F has some of the simple functionality of the board inside of it.) Is there some reason why the ITE directory does not contain code for the IT8705F although it has another ITE chip in there? I'm browsing the IT8705F specs right now it seems pretty thorough about how to control it. TODO list? - James Alton - jalton(a)olsh.cx

Geode problem with 2.4.19 SOLVED
by Ronald G. Minnich 03 Nov '02

03 Nov '02

It's a 2.4.19 change, I call it a bug, but maybe they had some reason? 2.4.19 code: /* * Cyrix: nibble offset 0x5C */ static int pirq_cyrix_get(struct pci_dev *router, struct pci_dev *dev, int pirq) { return read_config_nybble(router, 0x5C, (pirq-1)^1); } static int pirq_cyrix_set(struct pci_dev *router, struct pci_dev *dev, int pirq, int irq) { write_config_nybble(router, 0x5C, (pirq-1)^1, irq); return 1; } 2.4.17 code: /* * Cyrix: nibble offset 0x5C */ static int pirq_cyrix_get(struct pci_dev *router, struct pci_dev *dev, int pirq) { return read_config_nybble(router, 0x5C, pirq-1); } static int pirq_cyrix_set(struct pci_dev *router, struct pci_dev *dev, int pirq, int irq) { write_config_nybble(router, 0x5C, pirq-1, irq); return 1; } Note the ^1, which flips the low-order bit. I commented this ^1 out on 2.4.19 and everything works as it should. The error was consistent with an incorrect flipping of the low-order bit. I have no idea why this change would have been put into place, or if it was even tested. I do know some geode BIOSes have screwed-up IRQ tables in flash, so maybe they were fixing a problem but doing it the wrong way. Not sure. I know we have some Linux kernel guys on the list, forward to whoever needs to see this if you wish. ron

e7500 flash
by Andrew Ip 02 Nov '02

02 Nov '02

I have a e7500 with 82801CA. Before running the lastest flash_rom, I run 'setpci -d 8086:2480 4e.b=1' to enable bios write. Although flash_rom sees the flash, it fails to erase. Any idea? Or is there other way to flash it? -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.

Hi, After the lart project, I would like to know if some one has done a board with SA1110 and where I can found: 1) schematic, gerber, orcad files.... 2) Bios and Linux software 3) tools (compilator, linker, debugger)... 4) Application (do you know if there is a list of Lart/SA1110 applications ) 4) vendor board. Thank you for your help. When I will have answers I send you back. Jean-Francois
