2006-11-##  ?name?  <address@hidden> 

        Added new command "eptedit" based on code 
             derived from functions “partnew” and "parttype", 
             based on the patch by ?name? <address@hidden>: 
        * stage2/builtins.c 
             (eptedit_func): New function. 
        (builtin_eptedit): New variable. 
        (builtin_table): Added pointer to BUILTIN_EPTEDIT.

13.2.5 eptedit 
-------------- 

 -- Command: eptedit part slot type bcyl bhead bsec ecyl ehead esec rsec tsec 
     Change data in an extended partition table.  PART is a partition 
     specification in GRUB syntax (*note Naming convention::); SLOT is 
     the position in the extended partition table ("c" [current] or "n" [next]); 
     TYPE is the partition type and must be a number in the range `0-0xff'; 
     BCYL is the beginning cylinder; BHEAD is the beginning head; BSEC 
     is the beginning sector; ECYL is the ending cylinder; EHEAD is the 
     ending head; ESEC is the ending sector; RSEC is the relative sectors 
     and TSEC is the total sectors, both in sector units.  This is useful when 
     using extended partitions of different ranges to accommodate a mix of 
     “LBA aware” and ”LBA ignorant” operating systems, and to avoid the 
     “DOS/Win9x last logical partition bug” if you want to have a non-FAT 
     last logical partition.
