must create a boot diskette to bypass any memory managers (See Create a 

Boot Diskette, below).  

1. Boot DOS 5.0 or later version. (In Windows 95, at the boot option screen, 

 choose Option 8, "Boot to a previous version of DOS.") 

2. When DOS displays the “Starting MS-DOS” message, press .

After you press , DOS bypasses the CONFIG.SYS and AUTOEXEC.BAT 

files, and therefore does not load any memory managers. 

You can now execute Phlash. 

Create a Boot Diskette 

To bypass memory managers in DOS versions previous to 5.0, follow this 

recommended procedure: 

1.  Insert a diskette into your A: drive. 

2.  Enter the following from the command line: Format A: /S 

3.  Reboot your system from the A: drive. 

Your system will now boot without loading the memory managers, and you can 

then execute Phlash. 

                    Crisis Recovery Mode 

You should only have to operate Phoenix Phlash in this mode only if your 

system does not boot the operating system when you turn on or reset your 

computer. In these cases, the BIOS on the Flash ROM has probably been 

corrupted. Boot your system with the Crisis Recovery Diskette taking these 

steps: 

1. Insert the Crisis Recovery diskette  (which your dealer supplied or one 

    that you should have created from the instructions above) into drive  

    A:\. 

2. Reset your computer, power off-on, or press to 

    reboot the system. 

3. When your system reboots, Phoenix Phlash will restore the BIOS from the  

    diskette and successfully boot the operating system.
