INT 6F - HP Vectra EX-BIOS - "F_STR_DEL_BUCKET" - DEL HEADER FROM BUCKET LIST
	AH = 42h
	BP = 0012h (driver ID of V_SYSTEM)
	ES:DI -> bucket header (see #03775)
Return: AH = status (00h,FEh) (see #03744 at AH=00h"HP Vectra")
	BP,DS destroyed
SeeAlso: AH=00h"HP Vectra",AH=40h/BP=0012h,AH=44h/BP=0012h


Format of HP Vectra EX-BIOS bucket header:
Offset	Size	Description	(Table 03775)
 00h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to next bucket header (FFFFh:FFFFh if last)
 04h	WORD	upper bound on string index
 06h	WORD	lower bound on string index
 08h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to array of string offset pointers
 0Ch	WORD	segment of strings
Note:	the strings pointed at by the offset pointers are byte-counted ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL.
