(Pro/AutoPro)
There are three CompatiCard floppy controllers available from Micro Solutions,
Inc.; the CompatiCard I, II and IV.
The CompatiCard IV is the most popular because it allows the connection of
up to four floppy drives and it supports 2.88M drives and double speed 1.44MB
drives.
Compaticard IV Settings for DiskDupe:
DIP Switches and Jumpers:
- All switches down (off) on SW1 and SW2.
- Make sure that the jumpers on J2 are on Interrupt 6
and on both DMA2 positions.
- Put J1 on B for the 370 address, or C for the 360 address.
- Do not jumper J1 to A (the primary address) unless the original primary
controller (for A: and B:) has been disabled.
- Configure the new controller and drives in the Setup menu, starting with
the Controller List.
The P2 (internal connector) of the card is for drive positions 0 (twisted
cable) and 1 (straight cable). The P3/P4 external connector is for drive
positions 2 (twisted cable) and 3 (straight cable).
If DiskDupe reports a DMA error:
If a DMA problem arises then use DMA1 by moving the DMA jumpers on
J2 to DMA1 and also changing DIP switch 6 on SW1 to the on (up)
position. For DMA 3 put both switch 5 and 6 up on SW1. DiskDupe will
automatically detect these changes.
To access the drive from Dos:
(Please note: The Dos drivers do not need to be installed to access the drives
from the DiskDupe software).
If you want to access the drive connected to the CompatiCard IV from
Dos as a drive letter then you can load the CompatiCard drivers into
memory as explained on page 6-1 of the CompatiCard IV manual. It is best to
configure 3" double speed as if they were 2.8Mb drives (type 8) for the
CompatiCard drivers so that the high data rates for these drives are
supported. In this case the CONFIG.SYS might include the lines:
DEVICE=C:\CCIV\CC4BIOS.SYS /B
DEVICE=C:\CCIV\CC4DRV.SYS /B3,8,4,Y
We do not recommend that the on-board BIOS of the CompatiCard IV be enabled
because this often creates conflicts during the POST test (when booting the
computer), so make sure that you are using the DIP switch settings listed
above (all DIP switches off).
The CompatiCard Dos drivers will not work with SDS drives.
