Changing CPU causes extreme bootup delay

I changed the CPU in my motherboard. No other changes, just a 1.6 GHz
Northwood Pentium 4 upgraded to a 2.66 GHz Northwood Pentium 4 (same
Intel CPU family and fabrication geometry).

Now there is a full 3 minute "pause" in XP bootup. The screen is black
(it's after the initial XP boot screen and before the desktop appears),
and the system is totally non-responsive (caps lock and num lock do not
toggle the keyboard LED lights). But left alone, after 3 minutes, the
system does continue booting and everything is normal and works just fine.

There were no other changes made; same motherboard and all other
components unchanged.

Talked to a friend, and he said he has seen this before, with both XP
and 2K. On one 2K system, the pause was 15 minutes. He said that the
only thing he'd found that would fix it was a complete reinstall.

Does anyone know what causes this and is there any solution other than
reinstalling Windows (which would be a huge pain)?

This system is dual boot with 98SE, and 98SE boots fine. Also, if I cut
the CPU FSB from 133/533 to 100/400 MHz, the pause disappears, even with
the 2.66 GHz CPU (which operarates at 2.0 GHz if the FSB is 100/400
MHz). The motherboard is an Asus P4T533, if it matters.

Thanks for any input.

Does the new cpu have HT enabled? If so, try a =repair= install - you
may need a different HAL.dll in order to cope with the hyper threading.
Normally you only need a repair install if you change the motherboard,
but a significant enough CPU upgrade may do it, I guess.
