Hi!
|
|
<BR>
|
|
<P>Some FreeBSD user pointed this out to me earlier... you have to lock the file
|
|
<BR>
|
|
/dev/io in order to use inb/outb.
|
|
<BR>
|
|
<P>In a future release of the sanei_pa4s2 interface, this mechanism will
|
|
<BR>
|
|
be included.
|
|
<BR>
|
|
<P>regards

<EM>> I'm pretty puzzled with that, 'Inb (port: 890)' means access to CONTROL port.

<EM>> If the failure was due to lack of permission to do direct I/O, the umax_pp should
