Can I use DDR400 on a DDR2533 motherboard?

[i want a laptop]

So I order a Biostar combo (mobo and CPU) from directron.com and ram from newegg. I got the motherboard today, but no ram! UGH! So the minimum ram speed this motherboard does is DDR2533, but can I use some DDR400 just to like get into the bios or w/e? I am assuming no but I thought it can't hurt to ask.

Nope, won't work, ddr is 184 pins and ddr2 is 240 pins.
