Ifcpu64.c32
From Syslinux Wiki
ifcpu64.c32 is a comboot module for Syslinux that checks the CPU flags for 64-bitness (and optionally for 32-bit PAE support) and loads the appropriate label of/in the Syslinux configuration file.
This is only available in Syslinux 3.71 or later.

The use of "--" is required! The PAE is optional.
Example
Here is a config file:
LABEL ifcpu64-1 KERNEL ifcpu64.c32 APPEND system_64 -- system_32 LABEL system_64 KERNEL kernel64 APPEND initrd=ramfs.x86_64.cgz root=/dev/ram0 LABEL system_32 KERNEL kernel32 APPEND initrd=ramfs.x86.cgz root=/dev/ram0 |
