QEMM 7.5

More Memory for DOS, Windows, and Games

Quarterdeck Technology

Multitasking (DESQ, DESQview)
Memory Management (QEMM, QRAM)
Memory Analysis and Reporting (Manifest)
Networking and X Window (DESQview'X)

QEMM Features and Benefits

Creates a common memory pool
EMS, XMS, VCPI, High RAM
DPMI and DPMS use VCPI
memory supplied on demand
Applications get the memory they need
Users don't have to know or care about memory types
Frees up to 634K of conventional memory
more than any other memory manager
no memory type need be disabled
User has enough room for TSRs and drivers
Applications are faster
Larger DESQview, DESQview/X and MS-Windows DOS windows
Minimizes need for reconfiguration and rebooting
Moves more than 250K of TSRs and device drivers out of conventional memory
Creates 96K of High RAM by default
Stealth ROM provides up to 113K of additional High RAM
Stealth D*Space hides MS-DOS 6's DoubleSpace or DriveSpace in EMS
DOS-Up moves up to 70K of DOS above the 640K line

OPTIMIZE

loads TSRs and drivers in High RAM
invokes Stealth and Squeeze if needed
works around potential hardware conflicts

QSETUP

menu-driven configuration manager
allows for tuning of QEMM options

Manifest

comprehensive system and memory reports
suggests hints for optimizing configuration
provides editor for AUTOEXEC.BAT, CONFIG.SYS, SYSTEM.INI, WIN.INI

QEMM vs. DOS 6

much more conventional memory and High RAM
typically provides 100K more memory
more powerful memory management utilities
more memory inside MS Windows
support s DOS 6 multiple configuration feature
supports CALLed batch files

QEMM vs. DOS 6 Shootout

Typical system with

MS-DOS 6's DoubleSpace
SMARTDrive
VSafe
DOSKEY
Novell LAN WorkPlace for DOS
Microsoft Mouse driver
IBM VESA Driver
Configured with MemMaker (for DOS 6) and Optimize (for QEMM) QEMM vs. DOS 6 Shootout

QEMM 7.5: Enhancements

Improved memory management
Enhanced OPTIMIZE
Improved Stealth Support
Machine-specific compatibility enhancements

MS-Windows Install and QSETUP

Runs version appropriate to environment
Easy installation and configuration from
Windows' File / Run... command
DOS command line
Attractive graphical interface

Manifest 3.0

Runs version appropriate to environment from command line, DOS version under standalone DOS in DESQview, DESQview/X, or Windows DOS window from icon or File / Run, Windows version under Sidebar, Program Manager, or other Windows shell

Manifest 3.0 Windows-specific Features

Windows version of Manifest reports on loaded modules
Windows memory usage per-program
device capabilities
QEMM status from inside WIN /3
Manifest 3.0 New Features
- Both versions include reports on PCMCIA adapters
- CPUID information on new 486s
- PCI bus type reporting
- complete documentation on-line
- Hardware IRQs

QuickBoot

Allows for a faster reboot
Takes user to "Starting MS-DOS" immediately
Helps to make OPTIMIZE faster
Useful for those who change configurations often
Encourages you to reboot more frequently if that's what you want for safety or testing

Stacker Support

Co-developed by Quarterdeck and Stac
Allows Stacker to put its disk buffer in protected RAM
Saves minimum 8K of conventional memory or High RAM, depending on size of Stacker's disk buffer (cluster size)
On Stac'd CDs, saves up to 32K

PCMCIA Support

QEMM and OPTIMIZE now include special detection of PCMCIA hardware and drivers
Handles PCMCIA automatically
Can save memory if excessive EXCLUDEs are on the memory manager
Manifest reports on PCMCIA installation

QEMM Programming Interface

Allows programs to to request information or services from QEMM
Useful to third-party developers to alter behaviour of programs when QEMM is around to trap, read, or write I/O ports
Open, published specification for use by all

Improved Memory Management

Flat memory architecture
Faster than QEMM 7
Memory doesn't slow down when you're using more of it
Smarter hardware detection and ARAM detection

Improved OPTIMIZE

Retains database of pre-OPTIMIZE configurations
remembers pre-QEMM configuration
retains last nine pre-OPTIMIZE configurations
this means fail-safe INSTALL and OPTIMIZE
Now includes a step explicity for hardware detection
Copes with unusual hardware that needs XSTI
Includes PCMCIA detection and optimization

Improved Stealth Support

Better detection of areas of ROM and interrupts that need to be unStealthed
Copes automatically with new PCI/SCSI BIOSes

Machine-specific enhancements

Deals with ThinkPads that won't tolerate XBDA being moved
Adds special support for Toshiba video ROMs
Fixes for Compaq video ROMs and machines with > 16MB
