                            Novell Netware and Drive Type 47



Problem:       Certain versions of Novell Netware have problems using user-

       defined drive type 47.


Solution:      For Netware 2.12, 2.15, 2.2


               These versions of Novell Netware will not accept a pointer to a

       drive parameter table that is below C800:0000.  When drive type

       47 is selected, the data is copied into low DOS memory.  If BIOS

       Shadow is enabled, the data will be copied back into Shadow

               RAM (which is in the F000:0000 segment).


               In order to use drive type 47, ROM BIOS Shadow must be enabled.

       Not all chip sets and motherboards have this option.  The BIOS 

       date should also be 4/9/90 or later.  If Shadow is not 

       available, the only other option is to have a custom drive table

       burned for the BIOS.  This can be done by Upgrades Etc. 

       (800-628-8620) or Washburn & Co. (716-248-3627).  If the 

       motherboard has cache, it will be necessary to contact the

               motherboard manufacturer.




                       For Netware 3.00, 3.10, 3.11


               These versions of Novell Netware do not have the limitation of 

       the drive parameter table being below C000:0000.  However, they

       are sensitive to the format of the address pointer.  In some 

       BIOSes this address is not in a format that Novell will accept.


               If ROM BIOS Shadow is enabled, you can run the program 

       USERNOV.COM which will change the format of the address pointer.

       This program can be downloaded from the AMI BBS (404-246-5825). 

       This program will not have any effect is the ROM BIOS Shadow is

       not enabled, nor will it affect Novel Netware versions 2.12, 

       2.15, and 2.2.




If you need further assistance, please call AMI Tech Support (404-263-8181).

Evidence supporting quantum information processing in animals

Donald                    1068 Fulton Av                    Sunnyvale, CA 94089-1505                    USA I show that quantum systems can rapidly solve some problems for which finite state machines require a non- polynomially large time. This class of problems is closely related to the class of problems that animals can solve rapidly and effortlessly, but are intractable for computers by all known algorithms. 1.

ARMIES OF CHAOS

                          ARMIES OF CHAOS -      Before anyone proposes more gun control, he or she should know  about a simple, deadly weapon 4 times as powerful as Dirty Harry's  legendary .44 Magnum -- and at least twice as concealable -- that  _can't_ controlled.        This simple, deadly weapon can be made by anyone -- even a  child -- with unpowered hand tools in an hour's time using $5 worth  of materials, most of which are available around the house anyway.   In traditional form it's reusable an unlimited number of times, and  modern plastics have rendered its disposable version electronically  undetectable.  You can clear a room with such a weapon (more of a  hand-held directional grenade than a gun -- sort of a recycleable  Claymore mine) and it's just one of hundreds of similar time-proven  designs. ...
