   This is a boot sector for CD/DVD boot in "no emulation" mode.
   I.e, you can create bootable QSINIT CD without making "image diskettes".

   Just put CDBOOT.BIN, OS2LDR & QSINIT.LDI into the root of CD disk and type
something like this:

     mkisofs -l -V "QSBOOT" -no-emul-boot -b CDBOOT.BIN -o BOOT.ISO cdfiles

   Both OS2LDR.INI and QSSETUP.CMD are also welcomed.

   In fact, CDBOOT.BIN is a micro-FSD for CDFS file system. But direct OS/2
boot is not possible due to lack of mini-FSD & its support in CDFS.IFS.

   However, this mode still usable for boot from PAE RAM disk.
   Or this just can be a kind of "recovery tool".

   p.s. "micro-FSD mode" means that you can load any file from the root of
CD-ROM disk in QSINIT as it possible during boot from HPFS & JFS partitions.

   p.p.s. to change loading file name to something other than OS2LDR - just
type it over OS2LDR string in CDBOOT.BIN in any hex editor.

   p.p.p.s. starting from rev.550 this sector provides a fake BPB for QSINIT,
with a BIOS disk number, disk size (taken from ISO header) and sector size 2k.
This helps to mount boot CD as a boot volume in many cases of incorrect BIOS
information (since QSINIT now supports ISOfs).

   p.p.p.p.s. to create a dual-mode BIOS/UEFI CD boot image use something like
this:
     * get VPCFCOPY from "tool" directory in this archive
     * create "big floppy" image with UEFI boot volume:
         vpcfcopy.exe /floppy BOOT.IMG 3
         vpcfcopy.exe BOOT.IMG EFI\BOOT\BOOTX64.EFI QSINIT.EFI
         vpcfcopy.exe BOOT.IMG EFI\BOOT\QSINIT.LDI QSINIT.LDI 
     * prepare cd data and boot code for BIOS mode
     * run mkisofs.exe to make ISO file (example line):
         mkisofs.exe -l -J -R -V "QSINIT" -no-emul-boot -b CDBOOT.BIN
                     -eltorito-alt-boot -eltorito-platform efi
                     -no-emul-boot -b BOOT.IMG -o TEST.ISO cd_files_dir
     
       CDBOOT.BIN here is BIOS mode boot code
       BOOT.IMG is alternative boot file (UEFI system FAT volume image)
     * boot from it
       ** in BIOS - CDBOOT.BIN will be loaded
       ** in UEFI - BOOT.IMG will be mounted as UEFI system volume

     * Microsoft oscdimg.exe can be used instead:
         oscdimg.exe -j1 -bootdata:2#p0,e,bCDBOOT.BIN#pEF,bBOOT.IMG
                     cd_files_dir TEST.ISO
