 : What is a
Cookie and are they dangerous?
 :
A cookie is simply a HTTP header that consists of a string of data, that
is entered into the memory of your web browser by the web site visited.
The string contains the domain, path, lifetime, and value of a variable
that you set, when you visit the Web site. If the life time of the
variable is longer than the time the user spends at the site, then the
string is saved as a file on your hard drive for future reference.
This is not a new way for a computer hacker to hack your hard drive or spy in your
computer. All the programmer can do, is define the variable and its value saved there. The
browser writes to the hard drive, not the programmer. They are not dangerous.
: I am getting ntkern.vxd
errors when trying to setup my USB ports. What can I do
to correct this problem?
: NTKERN.VXD
errors are most often caused when USB cannot negotiate an
acceptable IRQ address. To correct this you will need to free some IRQs in the BIOS
and then delete the device entries from the Device Manager while in Windows Safe Mode. Follow the (5) removal
steps on the right in order --->
The Ntkern.vxd device loader(s) for this device could not
load the device driver.
See MS Knowledge Base Article 294292
Using a text editor add the following lines to the Autoexec.bat file:
SET windir=C:\WINDOWS
winbootdir=C:\WINDOWS
If you still cannot isolate USB to the IRQ,
changing the I/O range of USB sometimes works.
Power ManagementDisabled The Operating System should control Power
Management, not the mainboard.
ACPI - Disabled ACPI enabled in the BIOS is the
source of many USB problems. If you are having problems with USB, ACPI should be
disabled. Unfortunately, simply resetting the switch in the BIOS may not be
enough. Normally, a reinstall of the operating system will be necessary.

:I am having conflicts with my
USB. I get an ! next to the USB in the
Device Manager. What can I do to correct this error?
:
Despite information to the contrary, USB
does NOT like to
share its IRQ with another device, (IRQ Holder for PCI Steering is not
considered another device).
If USB is sharing its IRQ with Audio, Video, NIC or Modem you will
very likely have problems with USB.
Free as many IRQs as possible
in the BIOS.
A good place to start is COM1 and/or COM2 if you have no external
serial device attached to your computer. (i.e Serial Mouse or
Digital Camera) If you are using a USB printer you can also
Disable the Parallel port.
After disabling devices in the BIOS,
you must boot into
Windows Safe Mode and
delete the device from the Windows Device Manager. If the
device is not removed from the Windows Device Manager while in Safe
Mode, Windows will continue to recognize the device and assign it an IRQ.
Go to
Windows Safe Mode -> Control
Panel -> System Properties -> Device Manager
The order of
removal must be followed exactly in
Windows Safe Mode:
(1) Delete
USB peripheral devices
(Scanners, Printers, Cameras etc.)
(2)
Delete HID and/or Composite USB
(Human Interface Devices)
(3)
Delete
USB Root Hub(s) (Universal Host
Controllers)
(4)
Delete
USB Host Controller(s) (Universal
Host Controllers)
(5)
Reboot the computer into normal mode and Windows will reset the
USB
Moving peripheral cards to other available slots is
also an effective method of resolving IRQ conflicts. Each PCI slot
is assigned an IRQ by Default. Some PCI slots share an IRQ with
USB. Avoid those slots. Check the Mainboard Owners Manual
for this information and use it as a guide to avoid IRQ conflicts.
If freeing IRQs in the BIOS does not produce the desired result you can
manually assign an IRQ for a conflicting device in the Windows Device
Manager while in
Safe Mode. If manually
assigning IRQs you will need to Disable Plug and Play OS in the BIOS,
otherwise Windows will continue to override the BIOS assignments. If the
OS is installed in ACPI mode, IRQs assigned in the BIOS will be ignored
by the Operating System. |
