ok guys, thanks for all your help so far, but after many hours and five days it's still not happening. DPsbase did add some more mass storage devices to the setup; most notably an ITE IT8xxx ATA RAID controller but mine is and ITE IT8211 ATA ATAPI controller, so I still have to create a virtual disk with grub4dos, which I've successfully done and the setup can now access it. Only trouble is now that setup is asking for a disk labeled RDC D1010 ATA ATAPI Driver Diskette. But a disk label can only be a maximum of 11 chars . Just as an aside, where does setup get this label information from? Anyway, the cd that came with the computer had 3 drivers on, one for the graphics another for the LAN and finally the hard disk driver, so because the hard disk driver worked I assume that the other drivers are also the correct ones, unlike I first thought. Because I'm loading the virtual disk and setup through grub4dos I used method one with DPsBase. At first I tried slipstreaming all the drivers but it came up with a warning that the Oempnpdriverspath entry exceeded the limit of 4096 chars so I just slipstreamed the graphics a, b and c, the lan and massstorage drivers, because the driver disk only had drivers for these three things. Still it didn't work! Finally I tried loading the drivers that came with the computer onto the root of the virtual floppy image, in an attempt to get the setup to realise the corract drivers where available. Still no joy Any help much appreciated and hopefully together we'll crack this nut. I assume this is because this is a very new computer (only got it a week ago). Oh yes also tried integrating the drivers with n-lite but that didn't work either....
