First of all, thanks to friends like blue777, gandalf, magictek, wengier, and Deep Mountain Red Leaf!

This boot disk uses GRUB as the boot sector for multi-boot management. The functions of each item in the boot interface are as follows:

【Floppy Boot Sector】
1. When booting from the floppy disk, the green characters "PressAnykey boot A:,F7 Active HidePart" appear.
2. Press any key to boot the floppy disk. Pressing F7 will activate and boot from the hidden primary partition on your hard disk (provided that your hidden partition can boot).
3. After this boot disk is started, currently common hidden partitions will be assigned DOS drive letters and become visible.
4. Not writing to the MBR. After restarting, the hidden partition remains in the original state, and it will not damage your original one-key recovery, etc.
(Declaration: This part of the function uses the program for displaying hidden partitions by the无忧 member turboy (Teacher Yi).)

【GRUB Boot Interface】
1. Conventional MSDOS boot
2. Using the DDO boot file to boot MSDOS can break through the restriction that some BIOS do not support large hard disks.
3. Use GRUB's MAP function to boot the floppy disk image file on the hard disk partition.
4. Boot from the first hard disk
5. Boot from the floppy drive
6. Jump to BCDL to boot from the CD-ROM
7. Restart the computer

【DOS Boot Interface】
1. DOS boot only loads the hard disk driver and memory disk
2. Load support for CD/DVD and USB optical drive and other devices
3. Including items one and two, and support for PCMCIA and 1394 and other devices
