7 ---help---
8 The Simple Firmware Interface (SFI) provides a lightweight method
9 for platform firmware to pass information to the operating system
10 via static tables in memory. Kernel SFI support is required to
11 boot on SFI-only platforms. Currently, all SFI-only platforms are
12 based on the 2nd generation Intel Atom processor platform,
13 code-named Moorestown.
14
15 For more information, see http://simplefirmware.org
16
17 Say 'Y' here to enable the kernel to boot on SFI-only platforms.
