I want to use ISOLINUX and a COM32 image or a modified MEMDISK to copy a large chunk into RAM, and move a portion of this chunk (a COM program) down to 7C00h so that it can be executed similar to a boot sector. I've tried this with a COM32 image without much success, particularly due to my limited knowledge in Assembly. Any help would be greatly appreciated, but it would be even better if you can point me to some code that does this. Thanks in advance. -anh If you want to know exactly what I want to do, please see the following link: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnxpesp1/html/ram_sdi.asp __________________________________ Do you Yahoo!?
