AH = A1h AL = adapter number BH = Mode 00h = Real Mode 01h = 16:16 Protected Mode 02h = 16:32 Protected Mode 03h = 00:32 Protected Mode CX = Number of access offsets ES:EDI -> buffer supplied by caller, CX words long (see #00696)
CF clear if successful AH destroyed DX = number of access offsets supported ES:EDI unchanged CF set on error AH = error code (01h,15h,16h) (see #00656)
Desc: Returns an array of low-level adapter-specific optimized. PC Card access routines for adapters that use registers. Or I/O ports to access PC Card memory. Adapters that access. PC Card memory through windows mapped to host system memory. Do not support this function.
Note: Offsets returned are 16-bit offsets into the. Socket Services code segment. They must be called. Appropriately for the processor mode selected.. (Real, 16:16 and 16:32 modes use FAR CALL,. Flat 00:32 mode uses a 32-bit NEAR CALL).
