This is my attempt at using isapnp.conf to get the scsi card going. Can you give me some feedback on this ? pnpdump > /tmp/isapnp.conf I copied this to /etc/isapnp.conf, and uncommented the following lines -see arrows. # Logical device id SLI4163 # Device supports I/O range check register # Device supports vendor reserved register @ 0x38 # Device supports vendor reserved register @ 0x3a # Device supports vendor reserved register @ 0x3b # Device supports vendor reserved register @ 0x3d # # Edit the entries below to uncomment out the configuration required. # Note that only the first value of any range is given, this may be changed if required # Don't forget to uncomment the activate (ACT Y) when happy (CONFIGURE SLI4161/-1 (LD 0 # Logical device decodes 16 bit IO address lines # Minimum IO base address 0x0200 # Maximum IO base address 0xffe0 # IO base alignment 32 bytes # Number of IO addresses required: 32 (IO 0 (SIZE 32) (BASE 0x0200) (CHECK)) <-<-<-<-<- # IRQ 4, 5, 7, 10, 11, 12 or 15. # High true, edge sensitive interrupt (INT 0 (IRQ 4 (MODE +E))) <-<-<-<-<-<- (NAME "SLI4161/-1[0]{SYM 53C416 }") <-<-<-<- (ACT Y) <-<- )) # End tag...
