Hi folks! Unforunetely I have to confirm the error mentioned above... I get the same message about missing value in .sif file. I've prepared HFDRV folder as Oleg said to. I tried installing from source with and witout fdv's file set. Txtsetup.sif files look the same in both cases: (...) [SourceDisksFiles] (Here is a loooooong list of files) [SetupData] [SourceDisksFiles] HFDRV1.inf=1,,,,,,,20,0,0 [SourceDisksFiles] HFDRV.CAB = 2,,,,,,_x,39,0,0 [SetupData] DriverCabName=HFDRV.CAB,driver.cab [FileFlags] HFDRV.CAB=16 There are such lines in layout.inf from nonFDVed source, and not in FDVed one: [SourceDisksFiles] HFDRV1.inf=1,,,,,,,20,0,0 Dosnet.inf is the same in both sources: [Files] d1,HFDRV1.inf [Files] d1,HFDRV.CAB Please help us with it! Best regards! Btw. Am I wrong, or Oleg hasn't been visiting the board for a long time?
