HP Pavilion dv2000 laptop wont boot off install cd

[Kevin K]

I just tried to boot off the latest 8.0-CURRENT amd64 snapshot. According to
documentation, if you hold the spacebar as it is loading
/boot/default/loader.conf you can get to the boot menu. Pressing 6 and
entering :


 set hint.apic.0.disabled=1
 set hint.sio.0.disabled=1
 set hint.sio.1.disabled=1


Gets the laptop to boot. It crashing during the boot process however :
