HARDDISK

Accordingly,  it is possible to select the maximum or minimum level of noise,  or to vvvesti the average value of the level of noise into the
appropriate field (in the range 81h - FEh).

                        8.3. Password protection.

     This point of menu is intended for control of the subsystem of the
password protection of screw (Security management). Immediately it must warn, that for using this possibility it is necessary solidly to know, you want to make what.  If you place on the disk password and you will forget it, to remove password standard means it will be impossible. It is better here to not climb for the entertainment.
        Working window appears as follows:

HARDDISK

The field of input under the heading "password" is intended for the
input of password.
Password is the chain of any bytes,  what can be only introduced from the keyboard,  with length from 1 to 32 bytes. If a smaller quantity of symbols is introduced,  that program supplements the introduced password with gaps to the
right to 32 bytes. By switch the "type of password" can be established, what
password is introduced - user (User) or system (Master).
     Different instructions are executed by pressure on one of three
command buttons.

- to unblock screw.  This instruction opens access to the screw,
closed with password.  In the field of the input of password should be indicated correct
password,  and to select the type of the password (user or master) indicated. Afterward
the successful completion of instruction is opened access to the
operations of readingthe recording of the sectors of the user region of screw. With the installation of flag "to remove password" after successful
otkytiya of screw password protection is disconnected,  and further access to the sectors of data will be permitted
immediately after the switching on of feed of screw. For the repeated making more active of the protective system will have
to establish anew password.

- erasing data.  This is one of the versions of the operation of removing the
password,
with which the screw erases all user data. After the input of correct password and pressure on this button the
screw raises flag BSY,
it erases entire user region of data,  and then the subsystem of the password protection (is removed
password) is disconnected.  Procedure is useful for the obliteration of confidential data, storing on the screw.

- to establish password. Instruction is intended for including the subsystem of password
protection and installation of new password.  Preliminarily should be introduced future password,  to establish its type (user or master), and to also select the level of protection - high (high) or maximum
(maximum).
All details about the levels of protection and the special features of
the work of the subsystem of safety can be read in standard ata-6. One should consider, that
installation master- password to the nezaparolennyy screw in reality
does not lead to the making more active of the subsystem of safety.  Simply screw memorizes new master- password to the future.

     Again I want to emphasize, that the safety system of screw - this is not toy. Never forget, what password you establish.

                        8.4. Modes of the work of screw.

     This point of menu makes it possible to include or to turn off some
subsystems of screw - kesh of recording (write cache), the system of predvyborki of reading (read look-ahead) and extended
control of nourishment (advanced power management). Working window appears as follows:

The current modes of the work of screw are shown with the discovery in
the window. It is possible to switch them and to harvest key OK.  It must be noted, that the majority of screws does not memorize the established mode
after the disconnection of nourishment.

                       9. Window of the registers of screw.

     The window of registers - this is one of the most useful functions of
this program.  Strictly,  the program was written for it,  and it already then outgrew by supplemental service possibilities.  The window of registers is tool #y for the study of screw, since it possesses the in effect unlimited possibilities in the plan
of sending into the screw of instructions and exchange with it by the
units of data. As far as to me it is known, analogous
possibilities possesses only legendary HDD.EXE Vladislav Shakleyn (and her commercial version HRT), however, hdd.exe requires for its work even and Windows, which is far from always convenient.

        The window of registers takes the following form:

HARDDISK

Logically window is broken into three parts - region of registers, the region
the buffer of exchange and the region of the preserved instructions.

                        9.1. Region of registers.

     This region is intended for the work with the registers of screw -
sending to the screw of instructions and reading of results. It consists of two columns - region of output and region of input.
     The region of output reflects current contents of the registers of
screw after pressure to button "to read".  If we establish the flag of "auto-", that into this region will automatically load current contents of
registers after the execution of each instruction.
     The region of input makes it possible to introduce the specific value
into each of the registers of screw.  Pressure on the button "to send" writes these values into the
appropriate registers of screw - this is called sending into the screw
of instruction.  The result of executing the instruction can be seen, after loading
the values of registers by button "to read",  or it is automatic,  if
is established the flag of "auto-".  Contents of the registers of state (1x7) and errors (1x1) dynamically
are mapped into the line of the state of program.
     Separately should be noted register 1x0.  In contrast to the remaining registers of screw it has a size of 16
bits, and not 8, and it is intended for the exchange of the units of data.  Nevertheless some screws, for example IBM, in
a number of supers-command is used it as ordinary register for the
transmission of the parameters of instructions and reset of results.  In order not to disrupt the process of the exchange of data with the
screw, the following rule is accepted - if screw raised flag DRQ,  signaling about the readiness for the exchange of the unit of data, that register 1x0 is not read with program on the button "to read" and
is not written by button "to send".     In the remaining cases this register is readit is written, like remaining registers.

                   9.2. Region of the buffer of exchange.

     The buffer of exchange is intended for obtaining from the screw of the
unit of data and sending of the unit of data into the screw.  Buffer dynamically changes its size in the dependence on a quantity of
located in it data, and the current size of buffer is mapped into the appropriate field. Maximally possible size of buffer - y28K (256 sectors of data).
     When screw raises DRQ,  signaling about the readiness to transmit the chain of data,  the pushing of knob "to obtain" assumes data from the screw and places
them in the buffer. Data are read to those pores, thus far podnyat flag DRQ.  A quantity of read bytes will be shown at the end of reading the unit
of data in the field of size.  Old contents of buffer in this case is lost.  If we establish the flag of "<-->", that each pair it is byte in the buffer it interchanges the position
itself with each other (high-order bytes they will become low-order, A
low-order - by high-order).  This is useful,  for example,  for reading of the unit of the identification of disk.
     When screw raises DRQ for the reception of data, by button "to send" it is possible to send current contents of buffer
into the screw. Data are sent to those pores, thus far will not descend flag DRQ or data in the buffer thus far will
not end.

     Note.  The buffer of exchange program places in extended storage (XMS).  This requires the presence in system of driver HIMEM.SYS, or another method of extraction XMS- storage to program.  If with the start program does not obtain access to XMS- driver,   that work with the buffer of exchange is blocked, and the corresponding group of buttons in the window is not reflected.

                9.2.1. Retentionthe restoration of the buffer

     Button "to preserve" makes it possible to write down current contents
of buffer and file on the disk.  Buffer of zapisyvayetsyav the form of the neformatirovannogo binary
file by size,   corresponding to the current size of buffer.  Button
"to load" reads disk the file into the buffer indicated and is
established the size of buffer by the equal to the size of the
schitannogo file (maximum size - shchy2K).
     Pressure on any of these buttons leads to opening of standard file
dialogue.

                 9.2.2. Filling of buffer with information.

     Button "to create" fills buffer with the file of the bytes of the size
indicated.
The following window is opened with its pressure:

HARDDISK

Buffer can be filled or with identical bytes, indicated in the field the "code of filler",   or by unit- patterns.  The unit of pattern is the unit with the size of 512 bytes,    filled
by code- filler. In the first 4 bytes of unit its ordinal number in the buffer is
inscribed, and with address 10h is located signature * HDDL *.
     In both cases the size of the created buffer is indicated in the
bytes.

                 9.2.3. Surveythe editing of buffer.

     Button "survey" shows current contents of buffer in the form of
hexadecimal dump. To shut the window of the dump is possible of key ESC.
     Addresses in the dump can be shown in the absolute and relative form.  In the case absolute of addresses the address of each line shows
relative to the beginning of buffer,  and in the case of relative - relative to the beginning of the current
unit,  i.e., in each unit the addressing of lines begins from zero. Is switched the mode of addressing by button F8.
     With the aid of button F5 it is possible to pass to the survey of any
part of the buffer.
In this case in the mode of absolute addressing it is necessary to
introduce the new address of survey, and in the mode of relative addressing - new number of unit.
     There is a possibility of retaining the contained buffer into the disk
file (this operation it is the extended analog of button "to preserve"
the principal window of registers). Retention is carried out by button F2, in this case the following window is opened:

HARDDISK

Here it is possible to indicate the name of file for the retention, initial address and the size of the preserved section (in HEX- form), and also the method of retention - in the form of neformatnogo binary
file,  or in the form of text dump. In
the last case it is possible also to select composition pour on dump.

     In this version of program the possibility of the editing of the
buffer of exchange is also added.  Editor is called by key F4, and
the standard window HEX- editor is opened.  Sole limitation - to edit is possible only visible part of the buffer. Skrolling upwarddownward
it is not thus far realized.
     Button TAB transfers cursor from HEX- window in ASCII and vice versa. Button
F2 are written the made changes back into the buffer,  and button F4 - abolishes the made changes and perezagruzhayet
contents of the window of editing from the buffer.  Button ESC shuts the window of editing,
after which the mode of the survey of buffer is renewed.

                9.3. Region of the preserved instructions.

     In this the field it is possible to create the collection of the
predetermined instructions. In
each element of collection remains sozherzhimoye all registers (from
ykh0 to ykh").  The elements of collection have names, mapped into vertical list.

        The following buttons are accessible:

- to preserve.   On this instruction contents of registers 1x0-1x7,
locating in the fields of the input of the region of registers, it remains into the collection of the predetermined instructions by
the name, indicated in the field "description". I.e., for the recording of instruction, for example, reading the passport of disk, should be introduced in the field of the input of register 1x6 value
A0,  in the field of the input of register 1x7 - value EC,  then to introduce description the "passport of disk" in the field of
description and to harvest button "to add". in this case the instruction appears in the list of instructions.

- to remove. Instruction removes from the collection the chosen instruction.

- to load.   Pressure on this button leads to copying of all contained registers,  preserved in the chosen instruction, in the fields of the input of the region of registers.

- to execute.   Contents of registers,  preserved in the chosen instruction,  it is sent into the screw without the copying into the fields of the
input of the region of registers.  This is useful for executing different prefix instructions, the type
Super On.

     All predetermined instructions remain on the disk in the form ini-
file.
On kmolchaniyu the program uses file default.ini, if there is no such file on the disk, that is created empty file. It is possible to indicate the name of utilized ini- file in the
command line, furthermore, at any moment it is possible to load another ini- file with the aid of
the instruction "to select the file of the configuration" of menu
"file".
