## SUMMARY

The device driver for Corel optical drives may generate the following error message when restarting a system:
Sector size too large
To correct this problem, run the PATCH.EXE program supplied with optical drives by Corel Corporation. PATCH.EXE modifies the IO.SYS file to allow the recognition of a sector size greater than 512 bytes.

## MORE INFORMATION

According to Corel Technical Support, the PATCH.EXE program executes automatically the first time you install the optical device driver. However, any time you upgrade the MS-DOS version, reformat your hard disk drive, or perform any function that replaces the "patched" IO.SYS file, you must run PATCH.EXE again.
For more information, call Corel Technical Support.
