How to: Modify the PXE boot menu to allow the booting of .iso files
-
The thing about booting an ISO, is that you have to transfer the size of the ISO over the wire using tftp… Which can take long. The usual approach to live booting on PXE is to send a smaller image, then have the root mounted off NFS, so that it doesn’t have to wait until everything is loaded to boot.

Old thread I know but hoping someone can help me here.
I have edited the PXE boot menu before a few times (all thanks to this guide - thanks a lot ssx ;)) and never had a problem, however on this latest fog server I have set up I cannot seem to get it to work. I can edit the default file fine to display the menu options and also dropped the ISO files into the correct directory, but when ever I select one of them from the menu it only gets so far and then just says “loading boot sector… booting…”. It would appear that fog has found the iso and started to load it, but a problem lies somewhere else maybe? I have tried a few different memdisk versions, and this still happens on various ISOs such as Ultimate boot CD, Dell Diags, WinPE tools etc…
Any ideas on this would be greatly appreciated

[url]http://fogproject.org/forum/threads/fog-0-33b-edit-pxe-menu.10403/[/url]They both talk about how to add entries under the advanced menu system as many things are rather touchy with the BootMenu directly. That said, so long as there’s information contained in the Advanced menu, changes are likely things will work for your scenario.
Thank you,

Thank you.
It works, but only if the ISO is in the “www/fog” directory.
If I create an own directory “www/ISO” and set chmod to 777 it does not work. -
i keep my ISO files in a separate folder from www/fog, and it works fine and my permissions are set to 644.
have you tried testing the location you put into the “advanced” menu in a browser? it should ask if you want to download the file. -
Yes i tried testing the location in Chrome/Firefox/IE. I tried setting the permissions to 644 either.
I get the following error message: “[SIZE=4][FONT=Times New Roman][COLOR=#000000]The requested URL … was not found on this server.”
[/COLOR][/FONT][/SIZE] -
if the files are within your web root, and you can’t download them with a browser, then you almost certainly have the URL wrong. keep in mind that anything past the first / is case sensitive
-
Yes I know that. I checked it several times. The URL is not wrong.
I will do some more research tomorrow. -
if you provide a copy of what you put in your advanced boot options, i can help you troubleshoot it
-
What is the document root of the server? Is it /var/www or /var/www/html?
-
Yes, the DocumentRoot is /var/www/html.
If I try to post my advanced configuration options it’s marked as spam.EDIT: I changed the DocumentRoot to /var/www and the chmod of my folder to 777. Now it’s working.

What is the file that I have to use.
In syslinux-6.00.tar.bz2, into the directory memdisk there are many files called memdisk memdisk.:eek: -
none of those if you’re using fog 1.0+

there is a memdisk file located in <fog-web-root>/service/ipxe/memdisk -
I´m using fog 0.32. There are memdisk in /tftpboot.
Can I use that file? -
I´ve used memdisk from /tftpboot and it worked with fog 0.32:)
