 I looked at problem report 61739 and am not sure how to adjust my AGP 
 aperature size?  I did not see an option in my BIOS, is there a boot 
 option or sysctl variable which can be set?
 
 The aperature size is also lower than 256MB so I am not sure this 
 pr[68518] relates to that pr[61739].
 
 I have currently worked around the problem by installing freebsd on a 
 different machine, rebuilding the kernel without AGP support and then 
 swapping the harddrive into the offending machine.  I am happy to 
 continue working through the problem though.
 
 Thanks,
 Russ
