Section A - General Information about the IDEVL2
----------------------------------------------------------------------------------

1.  What is the IDEVL2?

	The IDEVL2 is a high performance Vesa Local Bus Enhanced 
	IDE Controller.  It supports up to four IDE devices under ATA 
	4.0, two floppy drives, two serial ports with 16550 UARTs and 
	one bi-directional parallel port with IEEE 1284 (EPP and ECP) 
	support.

2.  How can the IDEVL2 be helpful for me?
	
	The IDEVL2 provides a 32-bit Vesa Local Bus controller that 
	supports 4 IDE devices, two floppy drives, two high speed serial 
	ports and an enhanced parallel port all integrated in a single 
	adapter that will only take up one slot in your computer.
	
3.  What comes is bundled with the IDEVL2?

	-  IDEVL2 Driver and Utilities diskette
	-  Includes cables for two IDE devices and two floppy drives

4.  Where can the IDEVL2 be purchased?

	Boca Research enhancement products are available worldwide 
	through authorized Boca Research retail stores, distributors, or 
	many end-user catalogs.  To purchase Boca Research products 
	or for more information, call your local distributor or Boca 
	Research sales staff at (407)997-6227.

5.  What kind of warranty does the IDEVL2 have?

	All Boca Research products carry a five-year warranty.

Section C - Hardware Questions
--------------------------------------------------------------------------------

1.  How do I configure my hard drives, for Master or Slave?

	The first hard drive on the Primary IDE should be set to Master.  
	The Second drive on Primary IDE should be set to Slave.  The 
	first hard drive on Secondary IDE should be set to Master and 
	the second drive on Secondary IDE should be Slave.

2.  Why does the IDEVL2 need a driver?

	Although the board will still operate in 32-bit access without 
	drivers loaded, the DOS and Windows drivers for the IDEVL2 
	will enhance hard disk performance.

3.  How do you configure a third a fourth hard drive?

	In order to configure a third and fourth hard drive to the 
	secondary IDE port on the IDEVL2, you must either have 
	support for a secondary IDE controller in your motherboards 
	BIOS configuration or have a third party hard disk driver that 
	will add support for a secondary controller.

	Note:  The drivers supplied with the IDEVL2 are not designed 
	to configure a third and fourth hard disk.  This must be supported 
	by one of the options above.

4.  What Com ports should I set the Serial ports to?

	Before installing the IDEVL2, you need to find out what com 
	ports and IRQs are available in your computer.  There are many 
	system utilities available that will help you determine what 
	settings are used in your system.  The program MSD.EXE 
	(Microsoft Diagnostics) which is included with Windows and 
	DOS version 6.x and above can be used to determine what 
	settings are available in your system. 

5.  Does the IDEVL2 have built-in BIOS?

	No.  This controller relies on the motherboards BIOS for hard 
	drive configurations.

6.  Will the IDEVL2 support large hard drives with more that 1024 
cylinders?

	Yes, but your motherboards BIOS must have support for hard 
	drives with more that 1024 cylinders or have LBA (Logical 
	Block Addressing) support.  If your motherboards BIOS 
	does not have this support, there are also third party hard disk 
	drivers that support LBA.

7.  Can I use the IDEVL2's drivers with LBA?

	No.  LBA takes full control of your hard disk and will not work 
	with any other hard disk drivers, including the drivers supplied 
	with the IDEVL2.

8.  Can I use the IDEVL2 to control my CD-ROM drive?

	This controller can control an Enhanced IDE CD-ROM drive on 
	either the Primary or Secondary IDE interface.
