How to install windows NT4.0 device driver

1. Login NT 4.0 as Administrator
2. run "A:\nt4.0\nt4inst.bat" at NT DOS command prompt
3. shut down your PC
4. insert the CD-ROM PC-CARD into the socket
5. turn on you PC

Note
1. If your NT4.0 is service pack 1 then your internal CD-ROM drive
will be disable by NT system. So your must update your NT 4.0
to service pack 3.
2. NT 4.0 do not support plug and play. You must insert the PC-CARD
before boot up your system.

3. IRQ resource
3.1 for toshiba
a. Under Windows NT4.0 PC Card resource assignment and plug and play can be
problematic. Hot swapping or Hot inserting and extracting PC Cards will not
function in Windows NT 4.0. So first make sure the card is inserted when
the Notebook powers on and loads Windows NT 4.0.

b. If after the driver is installed and the system restarted with the PC
Card inserted, and the drive is still not seen verify the resources getting
assigned to the card.

c. Now for some Toshiba systems there is a tool on their web site at:

http://www.csd.toshiba.com/cgi-bin/WebObjects/Toshiba.woa/-/ServiceSupportMa
in.wo

Enter in the model number you are looking for in the Portables box (i.e.
7010), click on GO. Locate the PCMCIA Windows NT utility to download; i.e.
for the Tecra 8000 or Portege 7000/7010/7020 it is the T8KSYSNT.EXE file.

If the IRQ listed is not IRQ9 and you are using a Toshiba Portege 3010/3015
notebook, there is a conflict with their custom Windows NT IDE driver. The
symptom in this environment is that the Card and CD-ROM drive will function
only when the CD-ROM PC Card is inserted in Slot 0 (right side) and the
bundled modem card is inserted in slot 1 (left side)

--- --- --- --- --- --- -- -- -- -- -- -- -- -- -- --
b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
