The config files in the menu.lst sub-dir, please refer to the section If omitted, a standardĬonfig file in the menu.lst sub-dir will gain control. MENU_FILE specifies the config file on the PXE server. If it is not specified or it isĠ, then grub4dos will go through a probing process and get a proper value Now the "pxe" command has a new subcommand "detect":īLOCK_SIZE specifies the block size for PXE. You cannot directly map an image file on (pd).

As an example, if theīoot file name is /mybootdir/grldr, the Ethernet MAC address isĨ8:99:AA:BB:CC:DD and the IP address 192.0.2.91, it will try following Looking for a file named default (in lower case).

However, you may useĪ "pxe detect" command, which acts the same way as PXELINUX: Network, it will use its preset menu as the config file. The (pd)ĭevice is used to access files on the server. GRLDR can be used as the PXE boot file on a remote/network server. The default behaviour of GRUB4DOS is to unload The default value of base directory is the directory of the boot file,įor example, if boot file is /tftp/grldr, then default base directory Then all files in the pxe device is related to directory /tftp, forĮxample, (pd)/aa.img correspond to /tftp/aa.img in the server. Set the base directory for files in the tftp server. Tftp server where packet larger than 512 byte is not supported. This parameter is used primarily for very old Set the packet size for tftp transmission. If used without any parameter, pxe command will display current You can use the pxe command to control the pxe device. Option -raw works just like -force, but it load file in one go. When you use chainloader to load file from the pxe device, there is a option You must use -mem option if you want to map a file in the pxe device. The blocklist command will not work with a file in the pxe device.ģ. You can't list files in the pxe device.Ģ.

There are some differences between disk device and pxe device:ġ. Need to replace device like (hd0,0) with (pd). You can see that the menu.lst is very similar to normal disk boot, you just

This is a menu.lst to illstrate how to use files from the tftp server. If none of the above files is present, grldr will use its embeded menu.lst. The directory of the boot file, for example, if boot file is /tftp/grldr, then Here, we assume the network card mac for the client machine isĨ8:99:AA:BB:CC:DD, and the ip address is 192.0.2.91 (C000025B). Will scan the following location for configuration file: You may also want to load a different menu.lst for different client. You need to configure a dhcp server and a tftp server. You can setupĪ diskless boot environment using the following steps:
