can't even start the installation on MSI PR200

I'm trying to install the iAtkos 5i onto an MSI PR200 (Intel T5750 w/ 965GM Express, 2GB DDRII 667MHz, 12,1" WXGA (1280X800), 160GB SATA, Intel X3100 VGA).
I boot from the install dvd, press space to start setup, but right after the apple logo appears on screen (only for about 2 seconds), my laptop reboots.

If I try -s, it's just the same without the apple logo. In this case the last lines I see before rebooting are:
"Loading security extensions (...)
calling upo_policy_init for mb
Seatbelt MACF policiy initialized
Security policy loaded: Seatbelt Policy (mb)
Copyright (...)

MAC Framework successfully initialized
using 10485 buffer headers and 4096 cluster IO buffer headers
dsmos: Starting..."

And there goes the reboot.
