Installation guide
7
If you connected a new SCSI hard disk drive to your 
host adapter, you must partition and logically format 
the drive. For DOS and Windows (3.x and 95) use the 
AFDISK and FORMAT commands (see your com-
puter and DOS documentation). For other operating 
systems, see your operating system documentation.
Installing Multiple Adapters
■
You can install multiple SCSI host adapters if the sys-
tem resources are available (e.g., I/O port must be 
unique).
■
Each host adapter you install forms a separate SCSI 
bus with a different set of SCSI devices. 
■
In a system with multiple host adapters, all devices 
on each SCSI bus (attached to each host adapter) 
must have a unique SCSI ID.
Windows 95 Driver Installation
To make sure that your AHA-2910C driver software has 
been properly installed and is operating under 
Windows 95, do the following:
1
On the Win95 desktop click Start. An options menu 
appears.
2
On the options menu click on Setting and select 
Control Panel. 
3
Click on System. The System Properties window 
appears.
4
Click on Device Manager.
5
Click on the SCSI Controllers icon. 
6
If the Adaptec AIC-7850 PCI SCSI Controller is not 
listed, follow the instructions in the EZ-SCSI or the 
7800 Family Manager Set documentation for install-
ing driver support. 
OR
If you see a yellow exclamation point or red X in 
front of the listing for the AIC-7850 Controller, 
double-click the icon to see the error message and 
correct the problem. 
Using 
SCSI
Select 
The SCSISelect configuration utility allows you to change 
host adapter settings without opening the computer 
case. SCSISelect also contains SCSI disk utilities that 
allow you to perform a low-level format or verify the 
disk media of your SCSI hard disk drives.
Starting the SCSISelect Utility
To enter the SCSISelect utility, insert the SCSISelect floppy 
disk and then boot your system. To select either a color or 
monochrome display, press 
F5 
(this feature may not work 
on all monitors)
. 
Using SCSISelect Menus
SCSISelect uses menus to list the options you can select. 
To select an option, use either the 
Tab
 key or the up/
down arrow keys to move the cursor. Then press 
Enter
.
When you select an option by pressing Enter, the system 
may display an additional options menu. Return to the 
previous menu at any time by pressing Esc. To restore 
the original SCSISelect default values, press F6. 
Exiting SCSISelect
To exit SCSISelect press Esc . A message prompts you to 
exit (if you changed any host adapter settings, you are 
prompted to save the changes before you exit). At the 
prompt, select Yes to exit, then press any key to reboot 
the computer. Any changes you made in  SCSISelect take 
effect after the computer boots.
