Appendix G: If you have an ASPI card
The
AUTOEXEC.BAT
Note: This section is for advanced users.
When you install ScanWizard, the setup program inserts a DOS
driver called ASPIIF.EXE into a batch file called
AUTOEXEC.BAT.
Some users, however, may wish to free up memory occupied by the
ASPIIF.EXE driver. To do this, quit Windows, then go to the DOS
prompt. And at the WINDOWS\TWAIN\SCANWIZ directory, type
ASPIIF.EXE / U. This will unload the ASPIIF.EXE from memory.
