Hi
I have some strange problems enabling the sio0 and sio1 at
boot time.
If sio0 and sio1 devices are excluded out of the kernel
it boots perfect.
If I compile a kernel including sio0 and sio1 at boot time
the screen gets a blackout but the computer boots properly.
I can then do a 'blind folded' login and do an 'X -probeonly'
this gives me my screen back
have tried several setups in the configuration file like
giving the port adresses directelly but no difference.
#device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr
#device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr
device sio0 at isa? port 0x3f8 tty irq 4 vector siointr
device sio1 at isa? port 0x2f8 tty irq 3 vector siointr
If I do an dmesg it seems to me the sio:s are up
and also located correctelly. see message below.
I would be very happy if someone could tell a solution to my
sio problem.
