ADAPTER INFORMATION
===================

Displays a list of the adapters in your system, such as
printer ports (PRN#), serial port (COM#), hard disk
controller (HDD), floppy controller (FDD), or video
adapter (CGA, VGA, EGA, MDA).

All adapters have a base port addresses. Serial and
parallel ports have fixed timeout values. Floppy
controllers also have a timeout value. If an XT hard disk
drive controller is used, it also has a standard timeout
value.

An adapter can capture a hardware interrupt (from IRQ3 to
IRQ15).

This screen may take a few seconds to appear.

Hardware Information «
Hardware information
====================

Displays the hardware interrupts identified in your
system.

A hardware interrupt is a mechanism by which a hardware
device, such as a modem or keyboard, gains the CPU’s
attention. After receiving a hardware interrupt, the CPU
temporarily halts the current process and executes a
an interrupt service routine.

Hardware interrupts are associated with the 16 interrupt
request lines (IRQs) available to the CPU. Two Intel 8259
Progammable Interrupt Controllers provide 16 IRQ lines.
Controller 1 handles IRQs 0-7 and 2 8-15. IRQ2 on
controller 1 redirects IRQs to the second 8259.

TSoftware Information ‰
Software Information
====================

Displays a list of the software interrupts from 0h-7Fh.
Use the arrow keys, , and to scroll.

A software interrupt is the address (or vector) of a
systems program (or a table of information).For instance,
INT 13(hex) is the interrupt number for floppy and disk
I/O services,and INT 1B(hex) points to essential floppy
parameters .Each interrupt (that does not point to table
of informations) has an interrupt service routine. When
an INT assembler instruction is issued, control is
transferred to the corresponding interrupt service
routine.

EVideo Information Å

Video Information
=================

This screen shows the Video display system, including the
video display adapter type (MDA, CGA, EGA, or VGA) and
the monitor type (color or monochrome). The video mode,
display size, and video memory size for the current
monitor are displayed.

The video page size is the number of bytes in video
memory used to hold one full screen of data. If the
screen resolution is 80×25, the page size is 80x25x2, or
4 KB (both characters and attributes are stored).

The adapter RAM location is the address of video memory
installed on the adapter. If EGA or VGA, it may contain
additional memory that is paged into video memory.

0:3FF),the BIOS Data Area (40:0 to 40:FF) and the DOS
Data Area (50:0 to 60:FF). PC-DOS files IBMBIO.COM and
IBMDOS.COM or MS-DOS files IO.SYS and MSDOS.SYS are
loaded next. COMMAND.COM, installable device drivers, and
TSRs are loaded next. The remaining area to 640K is used
by DOS applications programs.

Display Memory at A000h resides on the display adapter.
Video Adapter card and hard disk controllers may have
BIOS firmware in ROM at C000 to DFFF. This area can also
host other Adapter ROMs, such as an Ethernet LAN
controller.

ïEMS Information 
EMS INFORMATION
===============

This screen describes the Expanded Memory in your system.
Expanded Memory is paged memory that provides
applications programs access to additional memory above
1 MB.

Expanded Memory is divided into 16 KB logical pages. A
logical page is accessed by a physical block (located in
the 640K – 1 MB area called a page frame. Physical pages
are also 16 KB. The page frame is a window to Expanded
Memory. Accessto the physical pages actually becomes
acess to the corresponding logical page.

If your system has Expanded Memory Manager (EMM), the EMM
Version Number, physical page frame addresses, and other
parameters are displayed. The maximum expanded memory
size is 16 times the number of available logical pages,
in KB.

This screen also displays the total number of logical
pages and the number of unallocated logical pages.
Logical pages can be allocated via a handle number. The
maximum number of opened handles is 256. Each open handle
has its own logical pages and may have a handle name. A
list of open handles with names and number of pages is
also displayed.
EXMS Information Ä
XMS INFORMATION
===============

This screen decribes the Extended Memory in your system.

Extended Memory is the RAM above 1 MB. DOS can access up
to 640K of memory, which is not enough for some programs.
The memory above 1 MB can be accessed via an Extended
Memory Manager (XMM). HIMEM.SYS from Microsoft is an XMM.
XMMs are usually installed in CONFIG.SYS.

If an XMM is installed, this screen displays the version
number and internal revision number. If the high memory
area (HMA) is enabled, memory from FFFF:10 to FFFF:FFFF
is available. This is the first 64 KB of Extended Memory.
Enabling the Gate A20 line enables addressing above 1 MB
and access to HMA.

5Disk y Disk Information …
DISK INFORMATION
================

This screen describes the logical disk drives in the
system. Use the arrow keys to scroll through the list.
The types are:

Assigned The DOS command ASSIGN has been used to
change the name of the drive.

Substituted The DOS command SUBST has been used to
substitute a directory for a drive.
“Substituted” is shown for the drive. The
directory name is also shown.

Block Devices These are devices which perform block I/O
and are controlled by a CONFIG.SYS device
driver.This is usually a RAM drive, such
as VDISK. The size of the drive and
default directory is displayed.

Network The drive is networked. The drive letters
start after the last logical DOS drive
through drive Z.

Hard Disk Hard Disk Drive C or D. The size and
default directory are also displayed.
JDisk Characteristics ­
DISK CHARACTERISTICS
====================

This screen describes disk drive characteristics. Use the
left/right arrow keys to select a drive.

Physical Characteristics

Displays the physical parameters of drives C and D, such
as the recording technology (MFM, RLL, ARLL, ESDI) the
drive RPM, and the Interleave Factor (the number of
sectors between two consecutive logical sectors. For
Interleave Factor 2, the sector format is:

1 10 2 11 3 12 4 13 5 14 6 15 7 16 8—-
ÚÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄÄÄÚÄ—–
³1 ³ 2 ³ 3 ³ 4 ³ 5 ³ 6 ³ 7 ³ 8 ³ 9 ³ 10³ 11³ 12³ 13³ 14³ 15—
ÀÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄÄÄÙÄ—–

Displays the drive parameters ( drive type, number of
cylinders, heads, and sectors per track, the landing
zone, the write precompensation cylinder, and so on.).
The landing zone is the cylinder where the head is
positioned when parked. Since all tracks contain the same
number of sectors, the recording density of the magnetic
media is not uniform. After a certain number ofcylinders,
the head write current is changed to compensate. The
cylinder number where this starts is the write
precompensation. Physical characteristics are available
only for hard drives.

Logical Characteristics

The volume label and disk parameter table for all
logical drives is displayed. A logical drive has four
parts: Boot Sector, FAT, Root Directory, and data area.
The starting sector of each part is identified. The
number of clusters on the disk, available clusters and
number of sectors is displayed. The cluster size is a
multiple of the sector size and identifies the minimum
allocation unit for the drive. Usually a disk has two
copies of the FAT. The number of sectors used by each
FAT is shown. If DOS version 4.0 or higher is used, the
drive has a Volume Serial Number of four bytes.

°Partition Table *
PARTITION TABLE
===============

This screen describes Partition Table Information for
each hard disk. Use to select drive C or D if the
system has two hard disks.

Each hard disk has a partition table at head 0, cylinder
0, sector 1. It describes how the drive has been
partitioned so up to four operating systems can coexist
on one drive. Only one operating system is bootable at
any time.

When the system boots, the BIOS reads the hard disk type
from CMOS RAM and uses it to read drive parameters. Then
it reads the partition table for a bootable operating
system partition.

This program identifies the following operating systems:
DOS-12, Xenix, DOS-16, EXTEND, BIGDOS, HPFS, Split, DM, GB,
Speed, 386/ix, Novell, PC/IX, CP/M, AIX, Beyond, and BBT.

ØDOS Autoexec.bat le ^
AUTOEXEC.BAT
============

This screen displays the AUTOEXEC.BAT file in the root
directory of the boot drive. Use the arrow keys, ,
and to scroll.

When the system starts, COMMAND.COM reads AUTOEXEC.BAT
and executes its commands. AUTOEXEC.BAT loads TSRs, sets
paths, and executes programs automatically at system
boot.

Common commands found in AUTOEXEC.BAT include:

PROMPT $P$G Sets the DOS prompt to C:\>.
PATH dir;dir Helps DOS locate programs and batch files.
SET xx=c:\y Sets environment variables used by
applications programs.

5Config.sys t le D
CONFIG.SYS
==========

This screen displays the CONFIG.SYS file in the root
directory of the boot drive. Use the arrow keys, ,
and to scroll through the screen.

CONFIG.SYS contains DOS configuration commands used to
start a program. When the system boots, DOS reads the
CONFIG.SYS file and interprets each line as an
instruction. See the following examples:

DEVICE=d:\path\filename Installs a device driver.
BUFFERS=nn Sets DOS sector caching
FILES=nn Sets maximum open files
àDOS Environment Î

DOS ENVIRONMENT
===============

This screen displays the DOS Environment Area.

After the system boots, the Master Environment Area is
created. The operating system reads AUTOEXEC.BAT, sets
the path and otherinformation, and stores all information
in the Master Environment Area. The first line of the
Environment Area is:

COMSPEC=C:\COMMAND.COM if the boot drive is C,
or,
COMSPEC=A:\COMMAND.COM if the boot drive is A.

Memory Block nt ‹
MEMORY BLOCK
============

This screen describes the current system DOS memory
allocation.Use the arrow keys to scroll the list.

DOS allocates blocks of memory to a program by storing a
Memory Control Block (MCB) for each set of memory. The
MCB describes the block size and its owner.

When DOS starts a program, it first allocates a memory
block for environment and then memory for the program.
When the program terminates, DOS frees both areas. If the
program remains memory-resident, the blocks are still
allocated.

In this screen, the memory blocks that have been
allocated to programs are shown. The size and address of
the memory block and name of the program are displayed.

If memory contains two TSRs and the first TSR tries to
remove itself from memory, a hole is established in that
region. In most cases, DOS will not reuse this hole.

TResident Program g
RESIDENT PROGRAM
================

This screen lists the Memory-Resident programs currently
in memory. Use the arrow keys, , and to
scroll through the list.

TSRs (Terminate and Stay Resident) keep part of their
code in memory when they stop execution and return control
returns to DOS.Sometimes a TSR uses a “Hot Key” to
activate the memory-resident code. The TSR executes when
the Hot Key is pressed.

TSRs have to be removed from memory in the inverse order
in which they were installed or a “hole” is created of
memory that DOS cannot access.

The starting segment address of the TSR is shown in hex.
The size of the TSR is the sum of all memory blocks used
for the TSR. The TSR name is displayed, if found. Memory
that does not belong to any TSR may either be free memory
or part of the DOS system area.
&DOS Interrupt a x
DOS INTERRUPTS
==============

This screen lists the DOS Interrupts from 20h to 2Fh in
the system. Use the arrow keys, , and to
scroll through the interrupts. Use the left and right
arrow keys to scroll the screen left to right.

A DOS Interrupt is the address of a part of DOS system
code.Each interrupt has a service routine. When an INT
instruction is executed, control is transferred to the
corresponding interrupt service routine. The address
column shows where control passes (the ISR address) when
the INT is executed. All DOS services are executed via an
INT instruction.

ÈDevice Driver a u

DEVICE DRIVER
=============

This screen displays the device drivers currently
installed in the system. Use the arrow (Left, Right, Up,
and Down) keys to scroll through the list. Device drivers
support peripheral devices attached to the computer. For
example, the LPT1 driver provides the low-level interface
between programs and the printer.
