Wow! Pci(e)? USB? Fw? What IZ interface? That's a lot better than I'm getting. What is your rig/desktop?

I hear you... I look briefly thru those to look for snares such as irq piling. The bios in this old Vaio is about a useful as a chocolate teapot! But I set CPU to performance in user spc (I think...) nowhere to deal with hyper. I don't think this dual core has it actually.

Could I trouble you to elaborate on last paragraph a little??
Thnks all for sharing!
