II.Card Types
There are 3 major types of PC Cards, designated as Type I, II, or III. Physically, all three card types have similar length and width (and use the same 68-pin connector. The difference between them is in thickness of the body of the card, Type I conforming to 3.3 millimeters, Type II 5.0 and Type III 10.5 . Type I cards are are typically used for RAM and Flash memory. Type II often used for fax/modems and networking cards are the most popular. Type III cards, the thickest include use with certain storage devices. There are also some extended cards whose body might extend out from the computer because of the device such as antennas for wireless communications.

III.A Short History of PCMCIA
A.PCMCIA Standard Release 1.0 (June 1990) The first release of the standard defined the 68-pin interface and Type I and II form factors. It also provided electrical and physical specifications for memory cards only. It also defined Card Information Structure (CIS) important for card operability and plug and play functions.

B.PCMCIA Standard Releases 2.0-2.1 (1991-1994)
A series of updates to the standard the provided specifications for I/O, dual-voltage memory cards, improvements in CIS and software interface (Card Services Specification).

C.PC Card Standard (February 1995)
Added information to improve compatibility, support for 3.3 volt operation, DMA support and 32-bit CardBus busmastering.

D.CardBus, the 32-bit PC Card
CardBus attempts to do for laptop and notebook computers what PCI (Peripheral Component Interconnect) did for the desktop, namely provide a new design so peripherals can connect to the system with 32 bit memory addressing and data transfer rather than 16 bit. Also included in this standard is support for bus mastering, which allows CPU functions to be offloaded between the PC Card and that part of the system the card is utilizing. Voltage requirements for CardBus cards are set for 3.3 volts or below. CardBus also supports PC Cards not utilizing CardBus, including backward compatibility with 16 bit cards and 5 volt cards. The original version of Windows 95 released in August 1995 did not support CardBus, however, Windows 95 OSR2 does support it. Additional support is provided by third
party vendors such as SystemSoft (http://www.systemsoft.com) and Phoenix Technologies (http://www.phoenix.com) who make card services software to interface such cards with laptop hardware and the computer operating system.

E.Zoom Video Card and Port
This is a card that fits into a PCMCIA socket. However, the PCMCIA socket needs to be Zoom Video compliant in order to utilize the card. The Laptops socket can still be used for other PCMCIA cards or adapters as well. The Zoom Video port standard allows a system to transfer video and audio data through a Zoom card directly to the VGA controller, bypassing the system bus and CPU. This significantly improves the speed of processing video and audio data. Full screen, full motion movies can consequently be viewed on laptops at about 30 frames per second. Zoom video has hit the market sooner than CardBus and up to now has been implemented on a 16 bit level.

F.CardBus and Zoom Video
CardBus is a broader standard that would relate to the development and manufacturing of any PC Card. It establishes 32 bit standards following the same signaling standards as PCI for desktop machines.

Zoom Video is a more specific solution for faster delivery of video and audio. However, this is only unidirectional in that it flows from the video source to the display.

Both standards are compatible, though Zoom Video would appear to be a shorter term solution that may not be needed after CardBus is fully implemented.

Note: Not all Toshiba Notebook computers offer Zoom Video Support. In fact, most recent models do not include Zoom Video support.

• 1.Invalid Page Fault in Module Kernel32.dll with Internet Explorer 5.0 installed
  ---or---
• 2.Explorer has caused an invalid page fault in module Kernel32.dll
• 3.Explorer has caused an invalid page fault in module Explorer.exe
• 4.Iexplore has caused an invalid page fault in module Browseui.dll
• 5.Microsoft Internet Explorer... There was an internal error

RESOLUTION:

a.Invalid Registry Entry

• 1.Restart the computer, press and hold down the CTRL key until the Windows 98 Startup menu appears, and then choose Command prompt only.
• 2.At the command prompt, type SCANREG /RESTORE and press the ENTER key.
• 3.Select a previous copy of your registry with a date prior to the problem, but after Internet Explorer 5 was installed (if known), and then press R to restore the registry.
• 4.Press the ENTER key when prompted to restart the computer.

b.Restore the registry to its default known good state in Windows 95.

• 1.Restart the computer, when the "Starting Windows 95" message appears press and hold the F8 key, then choose "Safe Mode command prompt only" from the Startup menu and press the ENTER key.
• 2.Type the following command and then press the ENTER key to move to the Windows folder CD \WINDOWS
• 3.Type the following lines, pressing the ENTER key after each line:
  ATTRIB -S -H -R SYSTEM.DAT
  REN SYSTEM.DAT SYSTEM.OLD
• 4.Restart the computer. Windows 95 uses the System.da0 file when it cannot find the System.dat file. If this file works, Windows 95 renames it to System.dat.
  

c.If Internet Explorer 5 was installed from a download or CD, try the following:

• 1.Choose Start/Settings/Control Panel from the taskbar.
• 2.Open the Add/Remove Programs applet, select Microsoft Internet Explorer 5 and Internet Tools, and then click Add/Remove.
• 3.Click Repair Internet Explorer, select OK, and then click Yes when prompted to repair the installation.
• 4.Choose Yes if prompted to restart the computer.

If Windows Displays a Blank Desktop:

• 1.Press CTRL+ALT+DELETE to start Task Manager (taskman.exe), select "Run Application" from the File menu, and then type CONTROL APPWIZ.CPL
• 2.Select Microsoft Internet Explorer 5 and Internet Tools and then click Add/Remove.
• 3.Click Repair Internet Explorer, select OK, and then choose Yes.
• 4.Select Yes if prompted to restart the computer.
• 5.Reinstall Internet Explorer 5.0 from CD or by executing the downloaded file.

d.Extract Comctl32.dll from the Windows Cabinet files.

Windows 95 users:

• 1.Restart the computer, when the "Starting Windows 95" message appears press and hold the F8 key, then choose "Safe Mode command prompt only" from the Startup menu and press the ENTER key.
• 2.At the command prompt, type CD\WINDOWS\COMMAND, and then press the ENTER key.
• 3.The line below should be on one line, do not press the ENTER key until you have typed "C:\WINDOWS\SYSTEM."
• EXTRACT /A /Y C:\WINDOWS\OPTIONS\CABS\WIN95_02.CAB COMCTL32.DLL C:\WINDOWS\SYSTEM
• 4.Restart the computer.

Windows 98 users:

• 1.Choose Start/Run from the taskbar. Type SFC and then click OK.
• 2.Click "Extract one file from installation disk", type COMCTL32.DLL, and then click START.
• 3.Click Browse next to the "restore from" box, double-click the C drive, double-click Windows, then Options, and then finally Cabs. Select OK.
• 4.The "save file in" box should display "C:\WINDOWS\SYSTEM." Click OK.
