INT 2F U - DR DOS 5.0 NLSFUNC - GET EXTENDED COUNTRY INFORMATION                
	AX = 14FEh
	BX = code page (FFFFh=global code page) (see #01757 at INT 21/AX=6602h)
	DX = country ID (FFFFh=current country) (see #01400 at INT 21/AH=38h)
	ES:DI -> country information buffer
	CL = info ID
	    01h get general internationalization info
	    02h get pointer to uppercase table
	    04h get pointer to filename uppercase table
	    05h get pointer to filename terminator table
	    06h get pointer to collating sequence table
	    07h get pointer to Double-Byte Character Set table
	CF set (used to return error if not installed)
Return: CF clear if successful
	    DS:SI -> requested information
	CF set on error
Notes:	DR DOS 5.0 NLSFUNC returns CF set and AX=0001h if AL was not 00h, FEh,
	  or FFh on entry.
	the DR DOS kernel calls this function on INT 21/AX=6501h
	the value in CL is not range-checked by the DR DOS 5.0 NLSFUNC
