说明
pxelinux-options is a man page documenting the DHCP options specific to PXELINUX, the network (PXE) booting variant of the SYSLINUX bootloader. These options are passed via DHCP to PXELINUX clients to configure their boot behavior. The options use DHCP option numbers 208-211 (site-specific option space) and allow the DHCP server to specify the configuration file, path prefix, and reboot timeout for PXE booting clients. These options must be configured on the DHCP server (e.g., ISC dhcpd or dnsmasq) to be passed to booting clients.
