	    CH = century (BCD(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits.  Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file.)
	    CL = year (BCD(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits.  Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file.)
	    DH = month (BCD(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits.  Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file.)
	    DL = day (BCD(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits.  Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file.)
	CF set on error
Notes:	DR-DOS 7.02 (after 1998-06-06) and 7.03 hook this function and correct
	  the century to 20xx if the reported year is 1900..1980 to auto-fix
	  ROM-BIOSes which are not Year 2000 compliant. On a running system,
	  it would also correct the rollover bug from 1999/12/31 to 2000/01/01.
	  The latter can be turned off using the new CONFIG.SYS YEAR2000=ON|OFF
	  command, as hooking INT 1Ah can sometimes cause compatibility
	  problems with 3rd party software, e.g. NCR/Symbios/LSI Logic-based
	  SDMS PCI SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer.	A host adapter connects the SCSI bus to the computer's own bus.  See also ESDI, IDE. drivers (including all OEM(Original Equipment Manufacturer) a company which purchases components that are resold as part of its own products under the company's own brand name, e.g. a Gateway 2000-branded monitor may actually be a Mag or NEC monitor. drivers like from Asus,
	  Noma, etc.), some Flash-BIOS software like Asus PFLASH, Quarterdeck's
	  QEMM Stealth and Quick-Boot features.
	Using EXCLUDESTEALTHINT=1A, though, will allow QEMM's Stealth features
	  to coexist with the DR-DOS Year 2000 rollover support.
	Actually, the Y2K-fix is provided since OpenDOS 7.02 BETA 2+
	  (1997-08-13), but although these older releases corrected the
	  ROM-BIOS, they didn't pass all Y2K-test suites and had some obscure
	  and inexplicable PCI problems due to the fact that the original
	  INT 1Ah was called via indirect means.  Newer releases, however, use
	  a dynamically fixed-up direct jump to avoid these problems.
	PCIBM PC DOS 7 plus Y2K fixes and PCIBM PC DOS 2000 provide similar, though not
	  identical means, which cannot be switched off.
	MS-DOS and older issues of PCIBM PC DOS do not provide any such means, and
	  thus requires extra Y2K-TSRs to be loaded when run on buggy BIOSes.
BUG:	some BIOSes, such as the 1998/07/25 system ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. in the Compaq Deskpro
	  EP/SB, leave CF unchanged if successful, so CF should be cleared
	  before calling this function
