Looks like I shouldn't be messing with the BIOS at all, I was only assuming this was the reason my restore was not working. What I am trying to acheive (I think) is to do a full backup of my original computer with Acrois Trueimage. Then boot the laptop from the Acronis universal boot CD and tell Acronis in which folder it will find the chipset, HDD and HDD controller drivers as *.inf, *.sys or *.oem extensions. Acronis should then be able to do a universal restore (to a computer with different hardware) using the drivers it finds to suit the new hardware after which I can load the remaining drivers to get the laptop fully functional. It appears to me that Acronis can't see sub folders so I need to know exactly which files I need so I can put them were Acronis can find them and there are an awfull lot of files that have been extracted from the .exe drivers (I already said I was out of my depth). I have attached a screen print of the .exe drivers I have downloaded, maybe someone could tell me which ones I need.
