Status: RO

Rather belatedly I have started to use ZCPR3.3 after several years of
using ZCPR2.  I am, however, having some trouble with the particular
installation that I would like to use, and I am looking for some
assistance.  
 
The system that I use is an Apple //+ with a PCPI Applicard CP/M card.
I have a 512K RAM disk on the Applicard.  I would like to arrange the
ZCPR3.3 system so that the RAM disk is drive A: two 5.25" floppies are
B: and C: and two 8" floppies are D: and E:  The standard Applicard
INSTALL process allows an AUTOST.COM file on either A: or B: (only).
After setting up various buffer areas and the PATH, AUTOST finishes by
invoking STARTUP.  I have successfully installed ZCPR3.3 by making the
first (boot) 5.25" drive A: the second 5.25" B: and the RAM disk C: etc.
However, if I try to make my desired configuration (RAM disk A: etc),
LDR.COM cannot find the SYS.* files, unless I put them on the A: drive
first.  This is obviously not practical in the case of a cold boot from
power off, as A: is the RAM disk.  
 
I think that I am using a fairly standard STARTUP alias (LDR
SYS.FCP,SYS.NDR,SYS etc...) and I have set the path as A0,A15,B0,B15.
With this path the SYS.* files cannot be found on the B:, which I don't
understand.  I have made up an alternative STARTUP alias which is 
LDR B:SYS.FCP,B:NDR etc, but the SYS.* files are still not found. It
appears that they must be on the A: drive for the boot to be completed.
Is it possible to change this ?  I have moved the SYS.* files onto the
RAM disk after an incomplete boot and then run STARTUP again and the
boot will complete properly.  Also if I leave them on the RAM disk and
do a cold boot without turning the power off (which I can do with the
Applicard), the boot goes through to completion.
 
I am obviously doing something wrong, as I cannot imagine that the SYS.*
files must be on the A: drive.  Any help would be appreciated.

P.S. also related to the above, I have found that if I am using DU (yes, the 
original version), and I try to write some of the Y)anked sectors to the 
A: drive, (e.g. KA0:filename.ext), an attempt is made to write to the B:
drive.  The resulting file seems to be known to the system, but I then cannot
find it with SWEEP.  Maybe I should not be using DU with ZCPR3.3.  I have not
checked this yet.
