Hunt) writes: Is it possible to run 386BSD with 4 serial ports (each having its own IRQ line by using IRQ 2 and 5)? What changes to the sources would be required? Any hints will be greatly appreciated... You can do it without changing the sources by adding the device's i/o port address and IRQ in your kernel config file. For example: cd /sys/i396/conf cp GENERICISA FOO edit FOO. Add something like: device com3 at isa? port 0x3e8 tty irq 5 vector comintr then generate the new kernel: config FOO cd /sys/compile/FOO make depend make mv /386BSD /386BSD.alt cp 386BSD / Rich --
