Isn't it more secure, easer to use an overlay program as to replace some lines of bios with nop and try if it's work flawlessly?
My disk is partialy full with datas. Is it a particular risk at the moment i install the overlay program to lose datas on one or more partitions?
After the install of overlay , i don't think to have trouble with fdisk or PM to create/modify partition, but with computer, you can never be 100% sure before

I admire the effort you all spend to solve this technical trouble but is it really the best method to modify the bios?
I understand that overlay technique is less satisfying for the brain but what are the disadvantages of overlay program?
