Having similar, yet less consistent problem. With an XP SP3 OEM source, option C yields varying results including: 1. An OS that BSOD's on boot 2. Failed installs due to missing files (similar to FDV) 3. Failed install when the i386/SVCPACK/HFSLIP.CMD is invoked Just changing to Option F is the medicine that makes it all better. This is all with a bare bones HFSLIP config: Host OS - Windows XP HFSLIP Version - 1.7.9_beta_g, build 81223 HFSLIP Path - C:\HFSLIPXP\ OS in SOURCESS - Windows XP Professional SP3 English Drivers - DRIVER.CAB Updated CD Install Path - Default CDTAG - WIN51 =============================================================================== Files in your HF folder: Files in your HFCABS folder: wbemoc.cab Files in your HFGUIRUNONCE folder: Files in your HFSVCPACK folder: Files in your HFSVCPACK_SW1 folder: Files in your HFSVCPACK_SW2 folder: Files in your HFTOOLS folder: BOOT.bin CDIMAGE.EXE Files in your HFCLEANUP folder: Files in your REPLACE folder: ===============================================================================
