Comment 5 Qunfang Zhang 2012-05-07 03:44:55 UTC 
Reproduced on seabios-0.6.1.2-8.el6 and verified pass on seabios-0.6.1.2-19.el6.

Steps:
1. Boot a windows guest
2. Check the 'Computer'-->(righ click mouse)-->Manager-> Device Manager --> System Device

With the old seabios:
There's 'High precision event timer' device in the list.

With the new fixed seabios:
No this device exist.

So, this bug is fixed.

When verified with the new fixed seabios, tried both the bios.bin and bios-pm.bin, and no this HPET device exist.
