Description:
|
|
In order to install DR DOS you must make sure that you are
|
|
booting from a floppy in drive A:. DR DOS will not install
|
|
from drive B:. DR DOS comes on 3 1/2 inch low density
|
|
floppies and 5 1/4 inch Hi-density floppies. If you need
|
|
5 1/4 inch low-density disks (360K) send in the coupon that
|
|
comes with your DR DOS.
|
|
|
|
If the boot disk hangs while trying to load, usually it means
|
|
there is an incompatible or faulty piece of hardware.
|
|
|
|
One of the things it can be is simply an older floppy
|
|
drive that is out of alignment. Sometimes the situation
|
|
can be salvaged by formatting a floppy on the boot drive
|
|
with the old DOS, then doing a diskcopy. The potential
|
|
problem is that the diskcopy may not be able to read the
|
|
boot disk either. If you can't make a backup then it may
|
|
be necessary to get a replacement disk set from Digital
|
|
Research (in case there is an actual error with the disk,
|
|
which does sometime happen) or see about getting the
|
|
drives aligned.
|
|
|
|
********************************************************
|
|
|
|
Another problem is where you can make valid Diskcopies
|
|
but all you get is the message "Loading...". Here the
|
|
potential problem may be the computer's bios. DR DOS
|
|
must be able to direct the system to the area where DOS
|
|
Kernel files are located. Older bioses are not able to
|
|
perform this function. If your bios dates from around
|
|
1987 or earlier you may need an update.
|
|
|
|
********************************************************
|
|
|
|
And finally, if you can read the disks but are unable to
|
|
format a disk or make a diskcopy DR DOS may think you
|
|
have a different type of floppy than you actually have.
|
|
Another symptom of this is if you are making a floppy
|
|
installation and DR DOS asks you for 5 1/4" floppies
|
|
when you actually have 3 1/2" floppies. If this is an XT
|
|
type computer (by which we mean it has no CMOS config-
|
|
uration program) then you can place a DRIVPARM state-
|
|
ment in your CONFIG.SYS. Refer to the DR DOS manual to
|
|
see how to use this parameter. DRIVPARM uses no RAM. It
|
|
merely updates the DR DOS drive tables with the type
|
|
drive you specify. If your computer does have a CMOS
|
|
setup program then you need to correct the entries for
|
|
your floppy drives in CMOS.
