[syslinux] quesiton about the mem=size option

[john_cutler at Dell.com]

I"m sorry if this is not the correct place for this question but i have not been able to locate any documentation on the mem=size  option for memdisk

The only thing  i have found is
mem=size           Mark available memory above this point as Reserved.

But i'm not sure if this is accurate and i'd like to understand the purpose of this option

I am PXE booting a LENOVO  machine which fails unless i add  mem=2048m  and i am trying to better understand what this is doing so I can better understand why this works but leaving it out fails.





sincerely,
John Cutler
