Brief
Get current directory
Input
- DL = drive number (00h = default, 01h = A:, etc)
- DS:SI → 64-byte buffer for ASCIZ pathname
Return
- CF clear if successful
- AX = 0100h (undocumented)
- CF set on error
- AX = error code (0Fh) (invalid drive)
Notes
the returned path does not include a drive or the initial backslash
many Microsoft products for Windows rely on AX being 0100h on success
