Sorry for the delay in responding, I'm trying to deal with the usual 15 things at once...

I've been using that, it autodetects the card type but it's assuming an Temic NTSC tuner when in fact it should be a Philips FR1216. > As for repeated crashes, I've got no idea what will be causing that. > Can you email me your grab.c test parameters and I will try it here. I've just been doing "grab 768 576 output.ppm", I've modified the #defines in the source to assume PAL. I was quite puzzled by the crashes until Jukka Simila emailed me and suggested: > I had similar problems and the answer was I had Intel 430FX-based > board so i needed the following in kernel: > > options "BKTR_430_FX_MODE" > > I noticed you have a 586 too, so maybe it is the same problem? And that turned on the little lightbulb in my head and I remembered I had all this happening in a reasonably old P75. Checking the motherboard revealed that it's using an SiS chipset (dmesg says chip0: <SiS 85c501> rev 0x00 on pci0.0.0 chip1: <SiS 85c503> rev 0x00 on pci0.1.0 ). I tried both BKTR_430_FX_MODE and BKTR_SIS_VIA_MODE but the lockups continued unabated - it appears that this mobo does not have a well behaved PCI bus. The lockups are definitely correlated with PCI activity, if I start up my little webcam shell script (just a looping grab and cjpeg) and then begin a "find / -print" the machine will lock hard almost straight away. Usually when I return to the machine and find it frozen, the HD activity LED will be on (but no drives will be moving). Is there anything simple that can be done with the brooktree driver to get the machine to be nice or will I have to bite the bullet and get a new mboard & CPU? -- C. -- Craig Harding crh@outpost.co.nz "I don't know about God, I Outpost Digital Media Ltd crh@inspire.net.nz just think we're handmade" http://www.outpost.co.nz ICQ# 26701833 - Polly To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
