This driver version support APA-1460 PCMCIA card for Laptops installed
with PCMCIA sockets and AIC6360 Adapter card as well. The Advanced Power
Management (APM) support also has been added for AIC-6360 chip used
internally in notebooks.

	After the notebook goes through a suspend/resume cycle, the
	user should be able to access the devices connected to the
	SCSI bus as before, if devices remain same. The system will
	not hang in the case where the SCSI devices have been removed
	after suspend.
	
	This release has added /SN command line switch for CDROM to
	run synchronously as well as other devices. Without this switch
	CDROM will run asynchronous (default mode).
	
This driver is based on OS/2 V3.0 (WARP) operating system. 

***** NOTE *****
Currently, only one APA-1460 card is supported.
	  						    
Installation instructions for the APA-1460 OS/2 2.0 PCMCIA Driver
				      
1) Open the OS/2 System folder, then open the Selective install.

2) Do PCMCIA installation.

3) Edit CONFIG.SYS file and add BASEDEV=AHA152x.add.			    

4) Copy AHA152x.add to \OS2\BOOT directory.

5) Do a SHUTDOWN and power off the system.

6) Insert the APA-1460 card into the PCMCIA socket and connect to the
SCSI peripherals.
		 
7) Power up and reboot the system.

***** NOTE *****
In order to install this driver for APA-1460 card, the system has 
to have OS/2 V3.0 pre-installed. Currently, IBM does not have the 
support for CDROM installation with any PCMCIA card attached to 
a CDROM. Therefore, it is NOT recommended to do OS/2 CDROM 
installation using PCMCIA card. 

Currently IBM does not have APM support for PCMCIA card.

Installation instructions for the AIC-6x60 OS/2 2.0 Driver
				      
1) Open the OS/2 System folder, then open the System Setup folder.

2) Select Device Driver Install.

3) Insert the driver diskette in the appropriate drive.

4) CHANGE to the directory where the drivers are located.
   The OS/2 2.0 driver files are usually in the OS2_20 directory.

5) When you have found the drivers, select INSTALL.

6) The system will be scanned for host adapters. If a host adapter is 
   found, you will see this message in a pop-up window:

   Installing Device Drivers

   Another message will appear when the driver has successfully been
   installed. If no host adapters are found, an error message will
   be displayed.


***** NOTE *****

If you are installing the driver on the GA release of OS/2 2.0, you
cannot install the driver by selecting the icon in the System Setup
folder. Instead, open a full-screen OS/2 session and go to the 
directory where the drivers reside. Then type DDINSTAL and press ENTER.


The driver includes the following features:

1) Double word PIO transfers.

2) B-mode DMA transfers (EISA systems only)

3) Fast SCSI support.

4) Backward compatibility with the driver for the AIC-6260.

5) Extended BIOS translation is supported on the AIC-6360.

6) Full support for all command line options.

Bug fixes since the previous (06/30/93) release:

1) Fixed problem in initializing DMA channel 6.

Changes made since the previous (07/30/93) release:

1) Supports BIOS new translation scheme (for BIOS signature
52H or 53H) for greater than 1GB hard disk drives.

Changes made to this driver since OS/2 3.0 WARP release:

1) Added PCMCIA support for APA-1460 card.

2) Added Advanced Power Management (APM) support for AIC6360.

There are new command line switches to support the new features on the driver.

AHA152X.ADD
This driver can support two host adapters and searches for them at ports 340H 
and 140H; boards are assigned adapter numbers in the order they are found.

Universal Parameters
	/SN - Allow synchronous negotiation (DEFAULT).
	/!SN - Prevent synchronous negotiation.

Special Unit Parameters

 	/BOFF:t - allows the bus-off time to be set to a value between 1 and
        15 microseconds. The default value for OS/2 2.0 is 4 microseconds 
        and this should be used for most systems. (05/03/93 and later)
	*** This option is only supported by the AIC-6360 and requires an 
	EISA system. 

        /BON:t - allows the bus-on time to be set to a value between 1 and 15 
        microseconds. The default value for OS/2 2.0 is 7 microseconds and 
        this value  should be used for most systems. (05/03/92 and later)
	*** This option is only supported by the AIC-6360 and requires an 
	EISA system. 

	/CHAN:x - Specifies the DMA channel to be used in DMA mode. The 
        available channels are 0, 5, 6 and 7. If an invalid channel is 
        specifed, then 5 is used by default.
	*** This option is only supported by the AIC-6360 and requires an 
	EISA system. 

	/D - Allow targets to disconnect from the SCSI bus (DEFAULT).
 	/!D - Prevent targets from disconnecting from the SCSI bus.

	/DMA - Use direct memory access to transfer data to/from the SCSI bus.
	*** This option is only supported by the AIC-6360 and requires an 
	EISA system. (05/03/93 and later)

 	/H:x - Specifies the host adapter SCSI ID. A number from 0-7 replaces x. The 
               default ID is 7. If you specify an invalid number, 
               the default is used.

	/PIO - Use programmed I/O to transfer data to/from the SCSI bus. 
               (05/03/93 and later)

       	/Y - Enable parity checking on the SCSI bus (DEFAULT).
       	/!Y - Disable parity checking on the SCSI bus.
