P4VXASD2 V3.3 CPU speed limit

I've bought recently a P4VXASD2 V3.3 from EliteGroup and I've been trying it with some CPUs. A 1,5 Ghz P4 was fine, but it failed with both a 2,4 Ghz 400 Mhz FSB Celeron and a 2,4 Ghz 533 Mhz FSB P4. As usual, the manufacturer site doesn't offer any help about this, but I've seen on some distributor...

It has 3 PCI slots, so PCI IRQ routing table has 4 entries plus one hardwired to USB controller's IRQ. The problem is that, although BIOS Setup allows you to disable IRQ assignation for VGA (...

I've got a PC-Chips M577 mainboards and I've been trying to solve some problems with its BIOS, as some of you may alreday know.
