Device Hints vs. FreeBSD 4.10 Release

2004-06-02 Thread Lonnie Santella
I've switched from FreeBSD 5.2 to FreeBSD 4.10 Release. I've lost the 
ability to edit the /boot/device.hints file, since it no longer exists in 
ver 4.10. This is critical to me since I need to add the mouse flag:

hint.psm.0.flags=0x100
This turns off the sync check which is what causes my mouse to jump all over 
the screen when I wiggle it. It's a PS/2 mouse - but plugged in via a 
Avocent 8-port KVM switch.

Is there another way to implement this type of port flag?
Thanks,
Lonnie

Yes, but you have to compile a custom kernel.  Instructions for doing
that are here:


http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html

What you need to do is take your kernel configuration file, and find
the line that says:

device  psm0at atkbdc? irq 12

and modify it to read:

device  psm0at atkbdc? irq 12 flags 0x100

If you think that the 5.x device.hint line is suspiciously similar to
that bit of kernel config, then you are right.  The 5.x 'device.hints'
mechanism is an interface to allow you to change such settings in the
kernel without actually having to recompile.

Cheers,

Matthew
