Fujitsu Siemens PC support P4 2.8 CPU

[mig3000]

Hi there,

i have a Fujitsu Siemens PC with original P4 (Northwood) 2.4 Ghz
Now i've put in a P4 2.66 Ghz (133/533MHz FSB)... runs good.

I've Tried to put in a P4 2.8 Northwood with HT technology but it schows up with 1.4 GHz, it think it need's 200 MHz FSB Quadpumped

is it possible to support this CPU in the PC?

Chipset: Intel i845G

BIOS is atached.
Here is a link for more Details of the PC:
