SMBIOS in WinPE ???

Hi, I’m trying to run SMBIOS utility in WINPE to get some information for automatic machine setup but it seems that it doesn’t work in PE environment or I’m missing some configuration needed by this utility. My goal is to get machine type (I’m using IBM machines) and this information is (AFAIK) not included in WMI. I’ve tried WinPE as well as WinPE 2.0 and I always get message that SMBIOS.EXE file couldn’t be found so it looks like some ACPI functions are not accessible in WinPE ?! Does someone knows how to get smbios to work or is there some other way how to get smbios information s in WinPE ? Thanks
