- 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.
