modification history
--------------------
02a,12oct09,j_z  updated AHCI vxBus driver support.(WIND00184020)
01z,24jul09,scm  Added AHCI support.
01y,27sep08,j_z  add support for INCLUDE_DRV_STORAGE_INTEL_ICH
01x,17sep07,kab  apigen cleanup
01w,18may06,dee	 SPR:117483, WIND00057492, WIND00057622
		 make compatible with XBD filesystems for 6.4
01v,14oct04,jb	 Fix compiler warnings
01u,18jul02,jkf	 SPR#79650, honor newer partition types, now will
		 avoid corrupting FAT32 partitions, added comments,
		 support big sectors and use malloc to use less stack
01t,26jun02,hdn/ dmh  updated revision no. in bootStrap[]
01s,25jun02,hdn	 replaced bootrom_uncmp with bootrom.bin
01r,04dec01,jkf	 using dosFsVolDescGet to see if device exists
01q,24may00,jkf	 new bootStrap 1.5, fixed SPR#31310,31445,30280.
01p,12nov99,jkf	 Added a bootStrap that has support for VxWorks long 
		 filename (VXEXT 1.0/1.1) matches vxsys.asm 1.4 version. 
		 Added comments.  Removed boot disk value update, since 
		 BIOS hands us the boot disk in dl, when the bootstrap is 
		 called. by convention.	 SPR#7452
01o,01oct99,hdn	 added support for binary file.
01n,08apr99,jkf	 corrected warning, SPR#26453.

01i,15feb96,hdn	 renamed to mkboot.c
01h,12jun95,hdn	 added support for ATA. added mkbootFd and mkbootAta.
01g,24jan95,jdi	 doc cleanup.
01f,25oct94,hdn	 added fdRawio() instead of using raw file system.
		 swapped 1st and 2nd parameter of vxsys().
01e,28may94,hdn	 updated the boot sector to DOS version.
01d,27jan94,hdn	 changed the entry point 0x10000 to 0x8000.
01c,16nov93,hdn	 changed name of the boot image "bootrom.dat" to "bootrom.sys".
01b,07nov93,hdn	 adopted Dave Fraser's idea.

DESCRIPTION
This library creates a boot diskette or disk.

mkbootFd() creates a boot floppy disk.
mkbootAta() creates a boot IDE/ATA disk.
mkbootAhci() creates a boot vxBus AHCI disk.  

mkMbr() creates MasterBootRecord on sector 0 of IDE/ATA disk.
mkMbrAhci() creates MasterBootRecord on sector 0 of vxBus AHCI disk.
