Machine freezes after Server.exe (No logger screen no error information)

I have completely and successfully went through setup of Netware 6 SP4 OS
Overlay on Intel i915PM (Centrino II on 1.86GHz Processor). Everything was
correctly auto-recognized during installation:
SATA HDD Drive, IDE DVD, LAN Ethernet Network Adapter Marvell - Chipset Yukon.
I always reach the end point of installation. After reboot system always
freezes on Server.exe in DOS(no logger screen). I have tried nw65osa.exe
patch but it is for earlier versions ov Netware 6.5 so it also crashes
server but in logger screen.
I don't know how to diagnose the source of problem(everything installed
without any porblems...)

Any Help / suggestions / Patches?
