EFI (Extensible Firmware Interface) When's it a cumin to replace bios? Anyone any info. What does it look like?
 
I believe its more then a GUI in technical wise Kempez , It slows them down. For instance a standard BIOS can only address 128K of option rom space. Most devices have option roms. So if you have an Adpatec scsi, a ATI video card and an Intel NIC. The BIOS loads these devices into memory. But lets say that the Adaptec device takes up 76K of option rom, the Intel NIC takes up 48K then there isnt enough for the video card or USB or any other devices etc(128K limit). Common tricks to get around this limitation are to change the PCI scan order or disable some devices in the BIOS. The bottom line is the whole boot process and interaction between BIOS and the OS will be smoother, more efficient and faster.

All boards that use the Intel 945 chipset support EFI, although it is currently disabled. A firmware update could enable EFI on these motherboards. I believe they are currently only on the Gateway 610 MCE, Apple MacBook Pro and the iMac Core Duo motherboards. It's interesting to note that Linux has been able to utilise EFI at boot time since 2000, but yet after confirmation from Redmond, Vista won't support it. Even the Intel 955 and 975 chipsets don't currently support EFI. :rolleyes:
