4.X or greater.
A110, A210, A110H, A210H, A120H, A220H, B20, B120x, B220x,
B120zx, and B220zx requires MSDOS versions 2.x, 3.x, and 4.x.
B44, B144x, B244x, Transportable 20, Transportable 44, and
Portable requires MSDOS 3.x or greater.
BOOTABLE ADAPTER ROM REQUIREMENTS
Booting from Iomega drives larger than 44Mb requires PC2B and
PC4B ROM versions 7.0 or greater.
ADAPTER BOOT SEQUENCE CHANGE
The PC2B adapter boot sequence when used with RCD 7.0 and ROM
version 7.0 is 0,1,2,3,4,5,6,7. If an older version of ROM is
used with RCD 7.0 or older the sequence is 3,1,2,0,4,5,6,7.
LASERSAFE ROM REQUIREMENTS
The Lasersafe drive must have ROM version IO07 or greater (Date
code: 103 or greater) to function with the RCD 7.0.
RCD 7.0 FEATURES
The Iomega Drivers for DOS manual provides detailed information
regarding installation and use of the RCD utilities and driver.
The listing below is a brief overview of features added in
version 7.0
1. The Lasersafe support has been added (512 byte disks only).
2. The RCD.EXE program can now be run when the driver (RCD.SYS)
is loaded into high memory using memory management software.
3. Only one operation at a time is allowed by the Iomega device
driver. This corrects some Windows 3.0 conflicts with the RCD
driver and RCD utility software.
4. PC4 now defaults to PIO (full Windows 386 compatible) mode.
NOTE: PIO options must be used with Microsoft Windows.
a. DEVICE = RCD.SYS = PIO (80386 and up) DMA (80286 hosts)
b. DEVICE = RCD.SYS /M = DMA - DMA transfers may be faster
on some system.
5. PC2 now has additional /Fx options.
NOTE: PIO options must be used with Microsoft Windows.
NOTE: /Fx options override the DIP settings on the
adapter. Example: If SW 4 is ON (PIO) but
/F3 is used then DMA Channel 3 is enabled.
a. DEVICE = RCD.SYS /F = Slower PIO (same as /F2)
b. DEVICE = RCD.SYS /F0 = Super PIO
c. DEVICE = RCD.SYS /F1 = DMA Channel 1
d. DEVICE = RCD.SYS /F2 = Slower PIO
e. DEVICE = RCD.SYS /F3 = DMA Channel 3
f. DEVICE = RCD.SYS /F4 = 8088 mode PIO
6. This release corrects most PPI adapter and 486/33 speed
compatibility problems. The driver does not, however, have the
ability to automatically choose the new transfer mode. The
transfer modes are selected by the following:
a. DEVICE = RCD.SYS = 8088 or 80286 and most 80386
models
b. DEVICE = RCD.SYS /P = fast hosts (80386/80486).
(PPI affected only by
/P switch.)
c. DEVICE = RCD.SYS /P0 = 8088 mode
d. DEVICE = RCD.SYS /P2 = 80286 mode
e. DEVICE = RCD.SYS /P4 = same as /P
NOTE: The /P mode should be used only if abnormal drive
behavior is seen on fast host (80386/80486) systems in
connection with the PPI adapter.
7. Write and Verify is now performed by all supported drives
using the write/verify (2fh) SCSI command except the Beta 20 and
Wren II (Bernoulli Box Plus HDA) drives. The Beta 20 and Wren II
verify options are still performed by separate write and read
(readback verify) commands.
8. The new RCD 7.0 PC2 and PC4 boot ROMs are LaserSafe
compatible.
9. RCDBACK, the archival backup utility, has been removed from
the utility package. The RCDREST.EXE stand alone program is still
included on the disk to allow recovery of disks that previously
have been backed up using the RCDBACK utility. RCDREST must be
operated in command line mode. For information on using RCDREST
refer to your RCD Utilities User's Manual and Reference Guide.
MS-DOS BACKUP and RESTORE or SitBack can be used instead of
RCDBACK and RCDREST if archival backup is needed.
10. The SETUP utility has been removed and replaced with an
INSTALL batch file.
11. The COPY function menu now contains a new field: WRITE WITH
VERIFY - ON/OFF.
12. The SCANS function of the TOOLS menu is fully functional
with all Iomega drives.
13. The HELP functions are now accessed by pressing the 'F1'
function key instead of the 'TAB' key.
14. The 'PAGE UP' and 'FORWARD TAB' keys now cycle through the
on-screen menu windows. The 'PAGE DOWN' and 'BACK TAB' cycle
backwards through the on-screen menu windows.
15. The source/target drive(s) can be selected by either the
up/down arrow keys or using the desired drives "drive letter"
such as the F key for drive F:.
16. The INSTALL function of the utility works with any
of the new '/' transfer mode options.
17. The FORMAT utility will not allow the DOS 2.X compatibility
option to be set to 'YES' on the LaserSafe or 44Mb drive
products. A /2 option has been added to the RCD FORMAT command
line option to allow 12 bit FAT's on any disks less than 44Mb.
18. A /N driver option has been added to lock all Iomega drives
during boot up.
19. A /L driver option has been added to lock the drives when the
MSDOS file open bit is set.
20. A /EI (Enable Interrupts) driver option has been added to
improve fast communication reliability when using a modem.
21. A /NL option has been added to allow the RCD Utilities to run
when a network present. Example: RCD FORMAT C:/NL
22. /A and /O options have been added to the RCD TOOLS command
line options to allow the drive to spin up (/A) or spin down (/O)
without pressing the drive release button.
RCD 7.0 LIMITATIONS
1. The Lasersafe support is limited to 512 byte sectored disks
only. 1,024 byte sectored disks WILL NOT function.
2. The RCDDIAG utility does not work properly with Iomega
products larger than 44Mb. Iomega does not recommend using this
program with drives larger than 44Mb.
3. The RCD FORMAT utility displays the message: 'Cannot run
utility while the driver is busy', and returns to the DOS prompt,
or Windows in Windows 3.0, if a format with surface verify is
running in another window with background operation enabled.
4. In windowing environments, such as Windows 3.0 and DeskView
386, that allow background operations, only one RCD utility
window should be used at any time. Attempting to use multiple
windows may cause the computer system to hang or cause the RCD
utilities to abort an operation. At the very least, a 'drive not
ready' error will be generated when the system attempts to access
a drive that is currently busy with another operation.
5. The RCD FORMAT utility does not allow the DOS 2.X
compatibility option to be set to 'YES' for 44Mb or larger Iomega
disks.
6. When using an IBM PS/2 Models 90 or 95 it is necessary to
first configure the fixed disk before installing or configuring
the PC4B adapter. When configuring the PC4B adapter the boot ROM
memory address must be removed otherwise the computer recognizes
two fixed disks. The PS/2 Models 90 and 95 can not boot from an
Iomega cartridge because these models are configured by IBM to
only boot from a fixed disk or floppy and the fixed disk can not
be removed.
USING THE MODEL PC4B HOST ADAPTER WITH A FIXED DISK
If your Micro Channel computer has a fixed disk, you must make
sure that the ROM on the PC4B host adapter is disabled. Make
sure that your Iomega subsystem is NOT on and then boot your
computer using the Reference Disk. Use the "Change
configuration" utility to check the ROM setting for the host
adapter. If the ROM is not disabled, select "Disabled" from the
ROM address options. After the ROM has been disabled check the
"Set features" menu for a "Set startup sequence" option. If such
an option exists, select it and make sure the fixed disk is
listed in the startup sequence.
IOMEGA DRIVERS FOR DOS USER'S MANUAL CORRECTION
Operation of the RCD INSTALL utility is different than that
described in Iomega Drivers for DOS User's Manual. The manual
states, on page 1-4, that the RCD INSTALL utility ignores any
existing reference to RCD.SYS in the CONFIG.SYS file if one
exists. This is incorrect. The RCD INSTALL utility deletes any
existing reference to RCD.SYS and adds the line "DEVICE =
RCD.SYS" as the first line in the CONFIG.SYS file. This
placement may cause problems with other device drivers loaded
from the CONFIG.SYS file. The "DEVICE=RCD.SYS" line may need to
be moved after such drivers in the CONFIG.SYS file. Any
existing CONFIG.SYS file is renamed CONFIG.BAK.
NETWARE 286 IOMEGA DRIVERS
Iomega drivers for Netware 286 are no longer included with Iomega
Interface Kits. If you would like to obtain this driver contact
your Iomega dealer or Iomega Customer Service. The Iomega part
number is 01512800.
AUTOMATIC INSTALLATION
1. The RCD SETUP program is no longer included.
2. Run the INSTALL batch file from the release diskette to setup
the new RCD Driver and Utilities on your boot drive.
MANUAL INSTALLATION
1. Copy the RCD Beta release diskette onto your boot disk in the
same location as your current RCD software (all adapters) or
create a path in the desired location on your boot drive then
copy the files from the release disk to the desired location.
2. If already running a PC2 or PPI (RCD.SYS) then simply re-boot
your system and run as usual.
3. If currently running a PC4 (RCD4.SYS) or if you are
installing the RCD software for the first time, then edit your
config.sys to add/change the line:
DEVICE = \pathname\RCD4.SYS to: DEVICE = \pathname\RCD.SYS
WARNING !!!
Failure to remove RCD4.SYS from the CONFIG.SYS file can cause
data loss and improper operation of the attached drives.
The old RCD4.EXE utility is no longer compatible with the new
version. The new utility version is accessed by typing
"RCD" from the MSDOS prompt.
4. Reboot your system.
5. Be sure to read the remainder of this file to understand any
other necessary options or changes regarding this software.
