Getting beyond the ATA 8.4GB limit
The current ATA interface uses 28 bit addressing. Unfortunately, most system
BIOS’s use 24 bit addressing which only allow a 8.4GB HDD. When the
system wants to read or write data to the disk, the BIOS has to use a software
interrupt. The main interrupt that is used to access the disk drive is interrupt
13h. This interrupt was assigned 24 bits of addressing, which only allows the
system to access 8.4GB on a disk drive. System designers were aware of this
limitation and defined extensions for interrupt 13. By mid 1998, most new
systems should have this support. Systems without the support can be
modified to use drives greater than 8.4 GB.
The Solution is to either obtain a new version of BIOS that supports the interrupt
13 extensions from the system manufacturer, or Load EZ-Drive software on the
system that links into the BIOS to add the interrupt 13 support (see below).
EZ-Drive Software Utility
If you have added a new hard drive and your system locks right after turning
the power on or when you are in the CMOS, you have a cylinder limitation.
The drive overlay software will create a new layer of software that will translate
to accommodate any BIOS limitations.
EZ DRIVE software from Micro House has been included in this package for
your convenience. Below is the instruction set for creating and installing the
drive overlay fix from the EZ DRIVE software.
Creating the EZ DRIVE diskette:
1) Insert the EZ-GIG diskette into the floppy drive. Open the diskette under My
Computer or Windows Explorer.
2) Copy and Paste the file “EZDRIVE.EXE” to your desktop. A new icon will
appear.
3) Double click on the new desktop icon and follow the instructions. You will
need a 1.44MB 3.5” floppy disk. Do not use the EZ-GIG Data Transfer
diskette for this purpose.
I
nstalling EZ Drive Software to your NEW Hard Drive After EZ-GIG
1) Boot your computer with the EZ DRIVE diskette in your floppy drive.
2) From the ‘Main Menu’ choose‘ Advanced Options’.
3) Choose ‘EZ-BIOS setup from the ‘Advanced Options Menu’.
4) Press the ‘Y’ key to install the EZ-BIOS translation fix.
5) Exit EZ DRIVE.
6) Remove floppy diskette from floppy drive.
7) Reboot your computer.
