I have integrated the driver for LSI MegaRaid Express 500, but at system partition selection I can only see the sata disk... Before I'm using the RVM Italian Update Pack 2.1.5.c that prevent the F6 screen form appear ( a problem with KB902845 ita), so I can install on the scsi disk , if I install Windows on sata disk at first logon the scsi card is installed and scsi disk is ready to use. Now I'm integrating normal hotfix and the scsi driver, at the system partition selection I cant see the scsi disk with integrated driver, but if I press F6 and load driver from floppy Windows tell me that there already is a driver for this hardware and if a tell it to load driver from floppy I can install Windows on the scsi disk. Investigating I have found that on [HardwareIdsDatabase] of txtsetup.sif there isn't the ID for the scsi card (but the ID for Sata controller is present), all the other sections seems to be ok for scsi driver loading except for the absence of the scsi ID. With nLite I have removed Windows xp scsi driver, is it the problem? Or is a problem with scsi driver integration? Thanks PS I'm Italian and I have to study english... Thanks Nuhi for your great work! When I have time I try to manually add the scsi ID to txtsetup.sif and tell yuo if work, it's about I week that I'm working with a friend's PC (scsi problem resolved via floppy driver, but a lot of problem with TV card, non nLite related) ULTIMA_SESSIONE.INI
