First post. This is not a request for any particular bios. My interest is in keeping quite old computers going. Many of these have SATA outlets on the mobo and it is possible to boot from a SATA HDD. However, none of them will boot a SATA CD/DVDROM. I've tried to do this through boot loaders without success. I've started reading the stickies, but I would just like to know whether my journey will be worthwhile, so that at the end of the day I will have BIOSes which will boot a CD/DVDROM. All the OSes, Windows and Linux distros use these drives without a problem,after the OS is launched, and Bioses on newer machines can boot from these drives. I'd be grateful for any help or advice.
