The same piece of hardware, the C drive is Fat32 with XP installed, and the extended partition D drive is Fat16 with DOS installed. Now I mainly want to ask for correction on the way to boot the DOS in drive D. The first one: title DOS map --in-situ (hd0,4)+1 (hd0) find --set-root /io.sys chainloader /io.sys The second one: title DOS map --read-only (hd0,4)+1 (hd0) map --hook chainloader (hd0,4)+1 rootnoverify (hd0) map --harddrives=1 Which one of the above is correct, or is there a better way to write it? Please be corrected by the experts! Learning...

The second one, why use --read-only write protection? Is it to prevent virus writing? The last sentence of setting the number of hard disks to 1 is also unnecessary. In case you have two hard disks, won't the second hard disk be inaccessible? --in-situ is generally not necessary. You don't need this when booting DOS. This option is designed to deal with Win98. It seems that this is better: title DOS map (hd0,4)+1 (hd0) map --hook find --set-root /io.sys chainloader /io.sys If booting Win98, you must use --in-situ.

Under the command line, the following can start DOS: grub>map (hd0,4)+1 (hd0) grub>map --hook grub>find --set-root /io.sys grub>chainloader /io.sys grub>boot Under menu.lst, the following cannot start DOS; it will return to the boot menu. At this time, if you select the XP item, it actually enters DOS. title DOS map (hd0,4)+1 (hd0) map --hook find --set-root /io.sys chainloader /io.sys [ Last edited by e98123 on 2008-6-23 at 12:22 PM ]

Does using map --in-situ (hd0,4)+1 (hd0) without the Master Booter allow booting into XP in that partition?

It is absolutely impossible to boot XP because disk emulation is ineffective for XP.
