  How does an Alpha-ROM protected application authenticate itself?
  The Alpha-ROM Digital Signature is added, using CD/DVD-ROM physical spec.
It distinguishes the authentic discs from copied ones.
Authentication process takes about 3~5 seconds and there is no need to reboot
or type additional serial number.
   
  What are the Alpha-ROM authentication options?
  Alpha-ROM has the following authentication options.
Online Authentication : Online authentication can be provided via
  Active X Control (OCX) The service provider can provide special online services
  to authentic users.
1 Time Authentication : At the first run, authentication is carried out. After that,
  the disc is not needed every time to run the application.
 ※ Counts and period of authentication can be configured.
   
  Can an Alpha-ROM protected application be copied with copying tools?
  The contents in the Alpha-ROM discs can be copied with copying tools such as
CloneCD, Alcohol, BlindWrite, etc. However, the digital signature can not be copied.
Therefore, when a copied disc runs, authentication process will fail with an error
message. The application will abort.
   
  Can Alpha-ROM be applied to a network supported application?
  Yes. Alpha-ROM supports a network supported application as long as each user
has an original disc to install and initialize the application locally.
   
  Is it possible to create protected patches for an Alpha-ROM protected
  application?
  Yes, one can create a patch for a protected application.
An application patch should be encrypted in the same project as the protected
application. The new protected patch can be placed on a webpage for end-users
to download. A protected application will still launch only if the authentic disc
is in the drive.
   
  What disc formats does Alpha-ROM support?
  Alpha-ROM discs are fully compatible with the CD/DVD-ROM complying
with the Yellow Book requirements as well as Mixed Mode and CD Extra
(Enhanced CD) For DVD-ROM, DVD5 and DVD9 are supported.
   
  How much storage space does Alpha-ROM occupy?
  Alpha-ROM occupies less than 10 MB.
   
  Can Alpha-ROM protect Mac and Unix applications?
  Currently Alpha-ROM protects applications for Microsoft Windows 98, Windows ME,
Windows NT 4.0, Windows 2000, Windows XP, Windows 2003 Server only.
   
  Does Alpha-ROM support PC/Mac Hybrid discs?
  Alpha-ROM can be used to protect the PC portion of the hybrid disc.
The PC executable file must be a separate entity from its Mac counterpart and
the application must be 32-Bit. Protection of the Mac portion is not supported.
   
  Does Alpha-ROM install any driver that may affect system?
  Alpha-ROM protects the application without installing any driver.
It is stable because it works in Window Application level thus the compatibility
of Alpha-ROM has been proven through various tests.
   
  How is compatibility of Alpha-ROM with optical drives and systems?
  Ongoing tests have shown that Alpha-ROM is compatible with over 99%.
A list of the optical drives and systems tested is available on request.
   
  Can Alpha-ROM be used to protect floppy discs or Mini discs?
  No, Alpha-ROM can not support floppy disc or Mini discs.
   
  Can Alpha-ROM protect multiple executables on a single disc?
  Yes, multiple .EXE, .DLL, and data files on a single disc can be protected.
   
  Does Alpha-ROM support a multi-disc program?
  If it does, do I have to protect all discs to run the program?
  Alpha-ROM is capable of protecting a multi-disc program by adding the same
Alpha-ROM signature to all discs. It will allow te program to be launched from
any disc. Also you may select a disc to protect and produce rest of the discs
as normal discs.
   
 
  I copied an Alpha-ROM protected application to my hard drive and
  it does not run.
  The content of a disc can be copied, but lacking digital signatures, a copy will
not work without the original disc in the drive.
