Mastering Sideways ROM & RAM - Module 02 - Rom headers
------------------------------------------------------
Paged roms and sideways rams can contain languages, utilities or
programs and data stored in the RFS. All roms, whatever they contain,
must be recognised by the operating system. To be recognised the first
dozen or so bytes must use the rom header format shown in figure 2.1.
The first 10 bytes of the header from &8000 to &8009 have fixed
positions in memory and must conform with the pattern shown but,
because the copyright and title strings vary in length and because
some of the rest of the header is optional, the header does not have a
fixed size.

Figure 2.1 The Rom Header
-------------------------
The first three bytes of the rom header (&8000-&8002) contain the
language entry point or, if the rom is not a language, the three bytes
will all be zero. The first byte of the language entry point is a JMP
opcode followed by the two byte address of the start of the language
coding. A language in the BBC micro can be any machine code program
which is completely independant of any other language and can take
over the processing of input and the production of output until
another language is selected to replace it. As far as the BBC micro is
concerned Word processors, spreadsheets and machine code monitors all
fall into the same category as the more readily recognised languages
Logo, Forth and Pascal. Language roms will not be considered until
module 17 and so, for the first part of the course, the rom headers
will all have zero in the first three bytes.
The next three bytes of the rom header (&8003-&8005) contain the
service entry point. All roms, except BASIC, must have a service entry
point. The first byte of the service entry point is a JMP opcode
followed by the two byte address of an interpreter which must process
the service requests made by the MOS. Service requests are made to
each rom in turn when, for example, the MOS finds an unrecognised *
command or when you type *HELP. The address of the interpreter is
usually the first byte after the end of the header, as shown in the
rom memory map, but you can assemble the interpreter anywhere you like
within the 16k of memory available to the SWR. The design of service
request interpreters will form a very important part of this course.
The byte at &8006 is the rom type byte you met briefly in module 1.
The rom type byte is a flag byte which tells the MOS what the rom is
expected to do. Bit 1 of the byte is always set on all roms except
BASIC and bits 0, 2 and 3 are always clear. Bit 4 controls the
Electron soft key expansions and is always clear on the BBC micro. Bit
5 is set if the rom is a language rom with the language coding
assembled to run in a second processor. Bit 5 will be clear in all the
examples covered in this course. Bit 6 is set if the rom has a
language entry and bit 7 is set if the rom has a service entry. All
roms, except BASIC, have bit 7 set. In the examples covered in this
course the rom type byte will have one of only two values. Service
roms will have &82 stored at &8006 and language roms will have &C2
stored at &8006.
&82 = 1000 0010 binary, ie. service entry point and bit 1 set,
&C2 = 1100 0010 binary, ie. language and service entry points and bit
1 set.
If you use the program READROM (from module 1) to look at some of
the roms you have in your computer there are two other values you
might find at &8006. BASIC has &60 stored at &8006 because it does not
have a service entry point and bit 1 is clear. "Hi" versions of
languages (except Hi-BASIC) have &D2 stored at &8006 because they have
a tube relocation address as well as language and service entry
points.
The copyright offset pointer at &8007 is the offset from &8000 to
the zero byte preceding the mandatory copyright string. The copyright
string must start in the first &FF bytes of the rom image and the
copyright offset pointer stores the least significant byte of the
address of the zero byte preceding the string. (See figure 2.2)
The binary version number at &8008 is ignored by the MOS. It can
have any value from &00 to &FF and is used to indicate the version
number of the rom.
The title string starts at &8009 and must end with a zero byte. The
title string is printed out by the MOS on selection of the rom as a
language rom. It will also be used as a command name in the simple
one-command interpreters used in some of the modules in this course.
The version string is optional and, if it is used, it must follow
the zero byte at the end of the title string. The version string will
not be used in any of the examples in this course.
The copyright string is essential because the MOS uses this string
to recognise the rom and, if it does not exist, the rom will be
ignored by the MOS. The format must always be a zero byte followed by
"(C)" and whatever else you want to include and then another zero
byte. The minimum copyright string is a zero byte followed by "(C)"
and another zero byte.
The tube relocation address, if present, is a 4 byte address at
which the language part of the rom has been assembled. Tube relocation
will not be covered in this course.
Writing the source code for the header is much easier that writing
about it. The optional version string has been left out of all the
example programs. The source code for the header of the program TRACE
assembles as shown in figure 2.2. You can see that it is &29 bytes
long but it could be shorter if it used the minimum copyright string
of "(C)". Figure 2.2 is a BASIC 2 version of TRACE assembled with bit
zero of the OPT directive set.

Figure 2.2 The rom header of TRACE
----------------------------------
When the MOS requests the paged roms to provide a service the
highest priority rom, rom &0F, is offered the first opportunity to
respond to the request. It is entered at the service entry point with
the registers set up as shown in figure 2.3.
Register Service call information
----------------------------------------------------------
Accumulator Service type requested
X register Number of current rom
Y register Any parameter required for the service
Figure 2.3 Service call registers.
----------------------------------
If rom &0F is unable to provide the service requested it must exit
using RTS with all three registers preserved and the next rom, rom
&0E, will be given the same opportunity to provide the service, and so
on down to rom &00. If a rom is able to provide the service requested,
and does not want any other rom to attempt to provide the same
service, the accumulator should be zero on exit.
The program TRACE is used to provide a display of the service
requests made to the sideways ram bank containing the object code it
generates. Chain the program and, when prompted, give a filename for
the object code which will be saved on disc or tape before you load it
into SWR. It is not necessary to include a quotation mark before and
after the filename. After saving the object code, load it into SWR
and press the Break key. You will immediately see a display of the
service requests sent to the roms when break is pressed. Type *HELP
and you will see the help service request. Type *DISC or *ROM or
whatever else you think will make service requests to the paged roms
and you will soon get to know the service request codes. Do not use
TRACE when *SPOOLing or *EXECing files. If you do it will cause the
computer to hang up. The service request codes are summerised in
figure 2.4.

service requested.

Figure 2.4 BBC B Service requests.
----------------------------------
The program TRACE works by intercepting every service request sent
to the SWR. Before doing anything else it preserves the A, X and Y
registers and the two zero page memory locations used by the print
routine by pushing them on the stack (lines 310,370). It then
retrieves the service request from the stack and pushes it back onto
the top of the stack (lines 380-400) followed by the Y, X and A
registers again (lines 420-470). It then selects a yellow foreground
colour if Mode 7 is used (lines 480-560) and prints the content of the
accumulator, the X and Y registers in hexadecimal (lines 570-680). An
explanation of the service request type is then given for the BBC B
service requests (lines 690-870). The Master computer uses service
requests not available on the BBC B and the content of the registers
for these requests is shown but not described. The program exits with
all the registers and memory locations restored (lines 880-990).
Having the trace active all the time is both distracting and
undesirable. You can disable the utility by read protecting the
sideways ram bank or by loading some other rom image to replace it.
Always press Ctrl+Break after read protecting SWR or reloading a rom
image.
Although the Master computer uses service requests that are not
available on the B series it uses all the B series service requests as
well. For this reason all properly written software for the BBC B will
also work on the Master but it will not make use of the the extra
facilities, such as paged workspace, without responding to the Master
specific service requests.
