Overview
allows you to patch the IO.SYS file on either a Windows 95 OSR2 or a Windows 98 bootable floppy for use as a boot image on bootable CD-ROMs.
In depth
The problem is that loading the CD-ROM driver resets the drive, and some CD-ROM drives take several seconds to reset, during which time your booting CD is unreadable.
Therefore, when CONFIG.SYS tries to load the command-line interpreter shell and any additional device drivers, such as COMMAND.COM, it cannot find them, and generates an error message, such as "The following file is missing or corrupted...". Needless to say, your CD does not completely boot.
The program enables you to modify your MS-DOS 7.1 bootable floppy's IO.SYS to allows the boot process to wait until the disk is readable before loading each device driver, and before loading the command-line interpreter shell.
In addition, it changes the text that is displayed when the disk boots to remind you that you are using a customized version of IO.SYS.
