Adding RAM to a Dell m6400

This is more for other people's information than my own. I upped my RAM from 2gb to 8gb and when booting afterwards, the system would repeatedly hang before the BIOS screen. I removed each module one at a time, finally getting down to zero and putting my old RAM back in. The problem persisted. Apparently when the amount of system RAM changes, it scans everything for quite a while or something. I really don't know why. It took nearly 5 minutes to boot the system. After that, I rebooted and it was fast as can be. Anyway, it was kind of nerve wracking and I was upset by the whole thing, so I'm hoping maybe someone will see this and be able to avoid the same stress I went through.

Also, here is the Dell service manual with instructions on how to get to the modules. http://support.dell.com/support/edoc...0/en/index.htm

Its just the Thorough BIOS check the system performs (as opposed to QUICK BIOS check). It automatically runs when the memory size changes or when the system failed to boot previously. It is rather annoying however.
