TANDY 1000 - NEW BIOS ROM VERSION 1.1

The following changes have been implemented in version 1.1 of the BIOS ROM for
the Tandy 1000:

1.  Modify the floppy BIOS driver to fix a bug in the VERIFY function.	The
problem is associated with multiple sector verifies.  If the first sector of a
number of sequential sectors in a multiple sector verify is read without error,
but one of the sectors after the first sector has an error, then the BIOS
VERIFY call will not return the error status for the faulty sector.

2.  Modify the video BIOS driver to fix the following bug:  when a read character
/attribute (INT 10H, AH=8) BIOS call is made, the characters that have an
attribute of 02 cannot be read.

3.  Modify the BIOS initialization code to fix the DMA mode compatibility
problem.  A hardware change to the DMA has been made and this software fix is
required.  This fix will allow "NETWORTH" to run.  A memory board modification is
also required.

4.  Disable the interrupts during the strobe pulse to ensure that the strobe
pulse is as short as possible.

5.  The video mode options available at boot time will be changed to work as
follows:

- If neither F1 nor F12 is depressed, the screen will come up in 80 x 25 color,
9-line.	 In the current ROM it comes up in 80 x 25 black and white, 9-line.

- If F1 is depressed, the screen will come up in 80 x 25 monochrome, 9-line
with all palette entries set to black, white and hi-intensity white.  This boot
option does not exist in the current ROM.

- If F12 is depressed, the screen will come up in 40 x 25 color, 8-line.  In the
current ROM it comes up in the 40 x 25 black and white, 8-line mode.

6.  Modify the floppy disk driver so that the drive A light doesn't come on
during a floppy reset.

7.  Modify the initialization code to initialize the internal speaker on/off
switch to on.  This change is needed because of a hardware change that allows
the internal speaker to be turned off.

8.  The version number changed from 01.00 00 to 01.01.00.

NOTE:  No ROM upgrade is available nor is it necessary.
