disk device driver will be recognized as a legal driver - all ready to use.
This disk now contains all the needed files to INIT and SYSGEN the hard disk, copy files to and from
it, and access it.
DVDDKGEN.ABS
This is the utility used to set the maximum number of partitions (logical drives) you will be using
with your DK.DVD device driver. You can have more partitions than that number, but you won't be able
to access them. For instance, you might have 8 HDOS partitions, but never need to access more
than two at a time. In this case you would DV DDKGEN DK1. You could then boot off the winnie
and do a MOUNT SY1:, but could not mount SY2: thru SY7:.
If you run DV DDKGEN (you don't have to, but will then use the full 2K memory for buffering as explained
below, since it will default to the maximum number of 7, being eight partitions, or 'logical
drives'), it should be run before you INITialize the Winchester with the new DK: driver. The
maximum value is 7 (which is how it is set when shipped to you), since you are allowed up to eight
devices per driver (example: DKO: to DK7:). Please keep in mind that each unit number requires
an additional 256 bytes of RAM, since HDOS allocates 256 bytes of memory for each possible disk
drive, up the maximum specified in the device driver. Thus, if you set this value to 3, you will use up
an additional 1K RAM beside the space for the device driver itself. If you set this value to the
maximum value of 7, you use up 2K RAM. Therefore, if you choose to use four HDOS partitions as
provided on this default, you should set the number to 3. If you only want to end up with only a
SYO: and SY1: (from DKO: and DK1:), you should specify 1.
The way to use this utility is as follows: When you have the driver copied on your HDOS SYSTEM
FLOPPY DISK renamed DK.DVD, (explained in the next section under DKSASXV3.DVD), be sure you also have a
copy of DVDDKGEN.ABS on the disk. Now simply type the maximum drive number as follows:
DVDDKGEN DKn:
where 'n' is the maximum number you will want. For our default having SYO: through SY3: (on hard disk,
but starts out on your SYSTEM FLOPPY DISK as DKO: through DK3: ), the maximum number would be 3,
thus
DVDDKGEN DK3:
will take care of it. INIT the HDOS partitions with the DK driver (INIT DKO:, INIT DK1:, etc.).
That's all there's to it.
