1.1 - Entering Registration Information for CheckIt 4

One point that was not covered in the manual is that you must 
register CheckIt 4.  To do this, you must make sure that the 
disk's write-protection is disabled.  Then, at the X-DOS 
prompt, type CHECKIT or SYSTEST for the respective 
CheckIt 4 disks.

A brief registration dialog will appear.  It's pretty simple.  
Just type in your name, company (optional), and serial 
number, then choose the OK button.  If you enter an incorrect 
serial number, a warning will appear, and you will be given 
the opportunity to provide a new one.


1.2 - Problems When Booting from X-DOS

X-DOS is the operating system that is used when you boot up 
your system from one of the CheckIt 4 disks.  There is a 
problem that arises only when you boot using X-DOS.  If you 
boot your system in MS-DOS, this problem WILL NOT 
occur.

Another way around the X-DOS problem is to create a boot 
disk using MS-DOS, then copy the CheckIt 4 program files to 
that disk.  For more details on how to do this, see section 1.3 
of this ReadMe file.  Otherwise, if you boot up in X-DOS, the 
following problem may arise:

Working with SCSI Drives Larger Than 512Mb

You may experience problems running CheckIt 4 on systems 
where the boot drive (usually the C: drive) is a SCSI drive 
that is larger than 512Mb.  If your system's boot drive is a 
512Mb-plus SCSI drive, make sure you boot from MS-DOS 
before running CheckIt 4.  Or, you can copy the files to the 
hard drive (to do this, see section 1.4 of this ReadMe file).


1.3 - Creating MS-DOS Boot Disks

As mentioned in section 1.2, another way around the X-DOS 
problems is to create a boot disk in MS-DOS, then copy the 
CheckIt 4 program files to that disk.  To do this, perform the 
following steps:

1.	Find a good disk, then copy the operating system 
onto the disk using MS-DOS' FORMAT command with the 
/U and /S switches.  The /U switch performs an unconditional 
format, which completely overwrites all existing data.  The 
surface of the disk is also check for defects (verified).  The /S 
switch copies two hidden files and the command interpreter 
COMMAND.COM onto your disk.  To format a disk in drive 
A: as a bootable system disk, use the following command 
line:

FORMAT A: /U /S

If your disk is in the B: drive, then you would change the A: 
parameter to B: in the command line.

You may want to create two boot disks for both of the CheckIt 
4 disks, the Portable Diagnostic Disk as well as the Burn-in 
and Certification Disk.

2.	Once your MS-DOS boot disks have been created, 
copy any drivers (e.g., mouse, CD-ROM, network) you need 
to one or both of the disks.

3.	Copy the CheckIt 4 program files to the MS-DOS 
boot disks (that is, all the files on each of the CheckIt 4 disks 
except COMMAND.COM).

Keep in mind, with MS-DOS boot files and any drivers you 
add already on a disk, you may not be able to copy all the 
CheckIt 4 program files to each MS-DOS disk.  You may 
need to be selective about which program files you copy.  For 
example, if you're not doing any CD testing, you don't need to 
copy the CKCD applet.  Another place to cut could be 
excluding the CKMEM applet since Qualitas' RAMexam is 
on the Burn-in and Certification Disk.


1.4 - Copying Both Disks to the Hard Drive

Because both CheckIt 4 disks contain some of the same files 
(especially the test applets), if you copy the contents of both 
CheckIt 4 disks to a hard drive, you may overwrite the 
redundant files.
