4.7.2.4 Rename Hard Disk File
To rename a hard disk file as shown in Figure 4–44, enter ‘5’ at the Hard Disk Mainte-
nance Options menu. If you change your mind about renaming a file, simply press
<return>, then you will be prompted to press <return> again.
Keep these points in mind regarding file names on a Freeway hard disk:
• The Freeway 1100/1150/1200/1300 hard disk uses an MS-DOS file system. File
names must follow the DOS convention of having a base name of no more than
eight characters followed by a period and an extension of no more than three
characters. File names for the Freeway 1100/1150/1200/1300 are not case sensi-
tive.
• Freeway 2000/4000/8800 uses the VxWorks DOS file system long name support
feature. This feature allows the use of file names longer than MS-DOS’s 8.3 con-
vention. These names can be up to 40 characters long and can be made up of any
ASCII characters. In addition, a period, which in MS-DOS indicates a file-name
extension, has no special significance. File names for the Freeway 2000/4000/8800
are case sensitive.
• The file names bootrom.sys and nvram.txt are reserved for Freeway 1100/1150/
1200/1300 use and may not be renamed.
• Each hard disk file name must be unique. As distributed by Protogate, the full
path names are defined so that uniqueness is ensured when the file names are cre-
ated on the hard disk. If you change the file names, make sure this uniqueness is
preserved.
