INT 2F - DR DOS 6.0+ IBMBIO.COM - RELOCATE THE BDOS AX = 12FFh BX = 0001h CX = 0000h (DR PalmDOS) DX = segment to relocate to (FFFFh for HMA) Return: AX = 0000h if supported Flags trashed BX,CX,DX,DI,SI,DS,ES destroyed (DR PalmDOS) Notes: This API is provided by IBMBIO.COM for the initialization phase of drivers loaded via DEVICE=/HIDEVICE=/DEVICEHIGH= directives and is only available during these short time intervals. It is initiated by DR DOS 6.0 EMM386.SYS and Novell DOS 7+ EMM386.EXE to relocate the BDOS kernel (e.g. into the HMA). This call is also issued by DR PalmDOS IBMBIO.COM which explicitly clears CX. Under Novell DOS 7+ the actual relocation takes place at a later stage, but under DR PalmDOS the BDOS is relocated immediately. SeeAlso: AX=12FFh/BX=0000h,AX=12FFh/BX=0003h
