I'm porting a device driver I wrote from BSDI to FreeBSD. The driver is for the Talisman MPEG decoder card (based on C-Cube CL480). Output is in a VGA window, or straight NTSC (Composite or S-Video). Does both Video and Audio and takes MPEG Systems streams in directly and parses internally. I'm running 021095-SNAP. The driver is working quite well, except for some reason when I have an SMC Ultra Elite plugged in I can't read reliably from the IO of the MPEG Decoder card, though I can write to it fine. The SMC Ultra Elite seems to stumble also. ed1 at 0x300-0x31f irq 10 maddr 0xd8000 msize 16384 (SMC Ultra Elite) tm0 at 0x700 irq 11 on isa The Talisman uses io ports 0x700-0x703 and that is it. It uses 8bit io. It works fine with a NE2000 card in place of the SMC Ultra Elite. I experienced this same problem under BSDI, so I expect it has something to do with the SMC card. Any ideas? I'm planning to publish the driver for all to use, so if access to the source would help at this point, let me know. Brian Litzinger brian@easynet.com
