Can you for the FPGA programming in the auto.c and issue an soft_reset in auto.c? YH -----Original Message----- From: Jay Miller [mailto:jmiller@actuality-systems.com] Sent: Tuesday, October 05, 2004 11:39 AM To: linuxbios(a)clustermatic.org Subject: Adding a PCI device that doesn't exist (yet) Hi All, The PCI interface to our "special sauce" is an FPGA that we're programming after the OS boots. The hardware doesn't have PCI hot-plug support, which means we're forced to reboot after programming in order to re-enumerate the bus in BIOS. Or are we? I was thinking of replacing the default scan_bus method with one that calls the default method for most devices and inserts the non-existent device information into the table at the appropriate time. Has anyone been successful at this sort of thing?

Thanks for your help. Certainly that's not ideal, but it may turn out to be our only option. Currently I'm investigating using proc_pci_attach_device() at the kernel level to add the device from the driver module init(post-program), but it's not looking promising.

I think this can work with the current mechanisms. You need to have your chip programmed pre-pci-scan, and the current config mechanism supports that fine. Is this V1 or V2, I forget. ron

Dave, your faq is now featured on linuxbios.org ron p.s. I screwed up the news page somehow, don't worry about it.

ebox-II SiS 550 flash_rom
by Trellix78＠aol.com 06 Oct '04

06 Oct '04

I've been trying to get freebios V1 to work with an ebox-II board that I have have. It has the SiS 550 northsouthbridge and some other cool stuff. However, flash_rom refuses to recognize the ROM chip or write to it. Is there a flash_rom version that'll work or do I have to modify the version that I currently have? Thanks... David

NXTV job posting

Sorry about posting this here but I think it might make sense seeing as NXTV is a linuxbios friendly company. http://www.xdr.com/nxtv-job.html -Dave PS The site + emails really represent nxtv.com, it is just easier to use my personal website for this.

i855GM/GMCH. I set up the registers, set up the MODE for a NOP, and on the first read, the whole thing hangs. Suggestions for what to do next, anyone :-0) Anybody seen good PC/104 or biscuit format Power PC systems? I'm getting a little tired of dealing with the intel side of the house, because the docs are so sparse nowadays. Pointers welcome. PPC 405 is no good: no floating point. thanks ron

Ron, Please change my second example in the testbios faq to Reflect Richard's change please.
