Edit C:\BOOT.INI, restricting Windows 2000/XP to use no more than a set amount of memory: by copying an existing
configuration line, adding /MAXMEM=XX (where XX is in Mbytes) and changing the prompt name, such as changing:
[operating systems]
multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows 2000"
to
[operating systems]
multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows 2000 [NT=64M PIXCI=256M]" /MAXMEM=64
multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows 2000"
Do not copy this new line as shown above; the first portion of the line must be copied from an existing configuration line in
your C:\BOOT.INI file. The text between quotes appears as a boot selection prompt, use of ''[NT=64M PIXCI=256M]'' is a
suggested reminder, but not required.
Also in C:\BOOT.INI, change the timeout selection to be greater than 0:
[boot loader]
timeout=30
Otherwise the BOOT.INI configuration options will not be shown when Windows starts.
Keeping the original configuration line, as a boot selection option, is highly recommended as a backup.
1.
Edit the registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW2
On the ''PIXCI'' field add:
-IA <image_memory_adrs_in_kbyte>
-IM <size_of_image_memory_in_kbyte>
-MB 8192
In practice, all three fields are on the same line. Be certain that the -IA address is equal to (or above) the specified
/MAXMEM limit - including exact base2 to base10 conversions! (i.e. for /MAXMEM=64, the smallest legal value of -IA is
65536, not 64000!). Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!
2.
Reboot, using the newly added boot selection.
3.
For example, for a PC with 1 gigabyte of memory, allocating 256 Mbyte for Windows and the remainder for frame buffer
memory, use:
/MAXMEM=256
in C:\BOOT.INI, and use:
PIXCI = -IA 262144 -IM 786432 -MB 8192
in the registry entry. Note that 262144 is 256×1024, and 786432 is (1024-256)×1024.
Note that if this memory allocation method is used, program access to image data may be slower. Thus, the video display rate
(and image processing) may be slower, but the video capture rate (such as sequence capture) is not adversely affected. This
method of memory allocation is primarily used for video rate acquisition of long sequences, followed by off-line analysis or saving
of the sequence.
3.6.4. Windows 2000/XP - Authorization Key - Manual Installation
Use of HLDINST.EXE, above, provides automatic installation of the printer port authorization key's driver, needed under
Windows 2000/XP, for XCAP-Plus and XCAP-Std (but not needed for XCAP-Lite). The following information allows manual
installation, correcting problems, or integration with an OEM's procedures for the printer port version of authorization keys.
The file HARDLOCK.SYS must be copied to the Windows SYSTEM32\DRIVERS directory, typically:
C:\WINNT\SYSTEM32\DRIVERS
1.
Using the Registry Editor (REGEDIT) provided with Windows, create an entry such as:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HardLock
This key must contain values:
ErrorControl = 0x00000001
Group = "Extended Base"
