Int 2F Fn 1A44  - Avatar.sys V0.11+ - Get Data Segment                     [V]

   AX = 1A44h
   BX = 4156h ('AV')

Return: AX = 0000h
   DS = data segment
   CX = size of data segment

Note:  AVATAR.SYS calls this function whenever it is invoked.  If each
     process under a multitasker hooks this function and provides a
     separate data segment, AVATAR.SYS becomes fully reentrant.
