EZ-BIOS

EZ-BIOS is code that installs on the boot sector of the hard
drive if your system BIOS does not support the full capacity of
your hard drive. EZ-BIOS helps your system overcome both
the 528 MB and 2.1 GB BIOS barriers.
528 MB Barrier: Most computer systems built before August
1994 do not support hard drives larger than 528 MB, unless
you update the system BIOS, install an EIDE controller card
with onboard BIOS, or install third-party software such as
EZ-Drive.
2.1 GB Barrier: Some computer systems built before early
1996 do not support hard drives with more than 4095
cylinders (hard drives larger than 2.1 GB), unless you update
the system BIOS, install an EIDE controller card with onboard
BIOS, or install third-party software such as EZ-Drive.
To determine if your system BIOS is set to support the full
capacity of your hard drive, EZ-Drive compares the system
CMOS settings to the actual drive size. If the values match,
EZ-Drive only partitions and formats the hard drive; it does
not install EZ-BIOS. If the values do not match, EZ-Drive
