Changesto the ROM Kernel Manual for the 1.2 Release
These notes have been assembled from a number of Alpha release
documents. You will find more than one mention of many features
and descriptions of problems that are later solved.
DOS
muchimproved dos, and some new commands.
look for 'addbuffers dfx: nn'
which will add nn buffers to the list of sector caches for drive
x.
Smarter caching and new disk layout. For optimal performance; relay
out your disk by using copy all. Details of CLI commands below.
Improvements include
New mode for opening files - MODE_READWRITE which opens an old
file
with an exclusive lock. (The actual value is 1004). Provided the
name MODE_READONLY as a synonym for MODE_OLDFILE. Look for new
dos.h. Requestors asking for a disk to be inserted are now only
displayed once the light on the disk has been turned off; thus
not
encouraging users to damage their disks so much.
CON: and RAW: parameter values are now not checked by dos; they
will be checked by intuition eventually but as of now they are
not checked at all.
Improved handling of sector allocation bitmap; should be fast for
hard disks.
RAM: handles parent(); allows null file name;
seek in empty file not now an error;
faster transfer rate; better out of memory
handling
Theramdisk released is about 30% faster than the 1.1 ram
disk.
ramdisk:now has an icon. It will appear whenever the ram disk
isbuilt. It is built whenever you touch ram disk with a dir,
orcopy something into it. You can't get rid of the icon though,
althoughyou can get rid of all the contents of the ramdisk.
Emacs
emacsfixed, now can use new rawinput code.
alphaversion of emacs. It supports 50 rows of interlaced stuff now.
supportsthe mouse
noteon emacs, the commodore-amiga supplied emacs is part of the
softwaretoolkit. It has been heavily enhanced and is not public
domain.
emacs documentation included on the Software Toolkit disk. Remember
this emacs is not a public domain emacs. Andy spent a lot of time
adding all kinds of goodies to make it easy to use on the amiga. It
is currently planned to be distributed to all who get the developers
toolkit.
Exec
expansion architecture now in kickstart!
Big side affect is that many system data structures should
now appear in fast memory if it is available. This is true
of
SysBase and GfxBase. So beware!
Bug fix, exec now correctly sets AFB_68881 in AttnFlags
For the next Beta release, there may be a new
function/libraryor something for you
68881 programmers. This would allow you to set up the
multitasking properly via tc_Switch,tc_Launch in exec. No
more multitasking problems with 68020/68881 combinations
(RSN)
Wehave partial 68881 support.
Moderatechanges to exec. Two feature areas: we now have support
forfinding code modules in ram at system bring up time (this lets
us ignore or add to modules in ROM) This new exec has a fully working
"romtagsin ram" facility. This
willallow one to override individual modules in kickstart. In
addition,new modules may be added to the system.
Inaddition several bugs were fixed. AllocAbs() was rewritten from
scratchto make it work. The exec library structure was not properly
kept-- LIB_POSSIZE and LIB_NEGSIZE were incorrect. In addition exec
usedto write over the top of legal memory on system boot.
includedseperate file, the latest exec.doc
Exechas new functions to deal with SignalSemaphore's.
Thereis one open design issue on this stuff. Because this "romtags
inram" is ram-based, there is a possibility of trashing the list
dueto an errant program. Currently the "directory" information
forthe ramtags is checksummed, but not the actual code and data.
Thismakes it possible to link in normal C code. However, it
meansthat a program can be trashed and your system will infinitely
loop,until the machine is powered off.
Apossible solution is to checksum the code as well as the directory
information. However, this means that only "clean" code may be used
--
e.g.code that is capable of being burned into ROM (even though it
isin ram).
Newfunctions: AddMemList() adds memory to the system
InitSemaphore(), ObtainSemaphore() for signal
semaphores
CopyMem() fast, safe memory mover
SunKickData()
Formore information, see the autodocs.
Finally,of interest only for those of us who write exec code, exec
willignore the old execbase if the version or revision of exec
haschanged.
Graphics/Layers
fixedscrolllayer, it wasn't recomputing the cliprects used to draw
intothe superbitmap when scrolllayer called.
XorRectRegionnow works. But removed, ran out of space on kickstart.
NotRegionremoved from graphics. It never did anything useful anyway
exceptblow up if you called it with correct parameters. You can
emulatedifferent forms of what you think NotRegion was supposed to
dowith XorRectRegion.
Changesto support different standard screen sizes.
Programmersshould get the NormalDisplayHeight of a screen from
GfxBase->NormalDisplayHeight.For NTSC this is currently set
to200 at power up and to 256 for PAL at power up. It is
intendedthat user preferences can make additional changes
tothese variables. Support for overscan displays is still
beingworked on. Tentatively there are also some new values
inGfxBase for max viewport height/width.
NTSCsoftware on PAL machine. Screens of 200 lines on a PAL
displayof 256 will appear at the position requested.
Screensare no longer bound to the bottom of the Display, they
maybe moved freely around. However there is no data displayed
belowthe topmost screen.(This was true in the previous release).
Usageof the NTSC/PAL bits in GfxBase are discouraged however
thosebits will be set correctly based on 262/312 lines per frame.
Includedwith this document are copies of any changed graphics
includefile plus sample program dotty.c These will also be provided
ona separate disk. Dotty.c can be expanded to use 256 line display.
Thereis a copy of the new trackdisk driver documentation.
Thereis a copy of the source for the animated pointer that Jim had
atthe UK Amiga conference. It demonstrates several basic and
advancedIntuition programming techniques, including pointer animation.
fixed d7 trashing in Text()
improved speed of Text() 9%-50% faster (1char-64char) strings
tad downcoded floodfill (about 1% faster) big deal. its a start.
fixed bug in color routines that try to make the top overscan color
be the same as the topmost viewport's color. It know lets the
bottom color wrap around if the topmost viewport has no colormap.
Like ea's Dpaint program.
fixedscrolllayer, it wasn't recomputing the cliprects used to draw
intothe superbitmap when scrolllayer called.
XorRectRegionnow works. But removed, ran out of space on kickstart.
NotRegionremoved from graphics. It never did anything useful anyway
exceptblow up if you called it with correct parameters. You can
emulatedifferent forms of what you think NotRegion was supposed to
dowith XorRectRegion.
better handling of SimpleRefreshLayer when moving layers.
CreateUpfront(BehindLayer) fixed. It now creates
the layer on top of all other backdrop layers as it
should.
XorRectRegion really installed for good now.
Bug fix in WritePixel, it wasn't waiting for the blitter
to complete between each of the blits. Consequently it is
a little slower now.
some minor upgrades to gel code, streamlining, cost reduction.
faster, quicker for less.
bug fix, ScrollRaster now correctly uses WriteMask when
clearing out the vacated area.
Gel code, faster, tighter. Expect about a 15% improvement
in
speed.
New graphics functions:
AndRegionRegion,XorRegionRegion,ClearRectRegion. See the
graphics.doc
Sprite movement now restricted to not go above hardware
limitations.
This means that the absolute starting position of a Sprite
must not occur before line 20.
gfxbase.h change see the include file
mainly: name change from DPI->DPM The meaning
to ascribe to this value is DotsPerMeterX/Y. Use these
values to calculate display aspect ratio. These numbers
will be different between NTSC and PAL.
faster flood fill, should be about twice as fast.
layers:
fix of sizelayer/movelayer with superbitmap window. It would trash
the bits if the scroll position was other than 0,0.
this was actually fixed in alpha-3, did I already mention it?
New
routineSetRGB4CM(cm,i,r,g,b)
similar to SetRGB4() except this routine takes a ColorMap
as a parameter instead of ViewPort.
Due to consistent prodding from glenn at EA, I've finally fixed
the FreeSprite() bug, it failed to turn the sprite off normally.
See, you guys out there can make a difference.
Note:to you guys that assume you can just play around with the
ColorTable ptr in ColorMap, What happens if I go to a 5bit
per color colormap. Have you just screwed yourself into a corner?
I know, maybe I should have gone to 8 bits per gun right away.
We live and learn.
new"ed" fixed bug when run in an interlaced workbench screen.
increased buffer again for PAL interlaced displays, boy you
guys just want everything!
fixed AreaEnd, it now returns 0 if no error occured.
fixed top overscan color to match top viewport as long as
it has a colormap. (Pay attention you cheaters).
Slightly retouched fonts. Two new Functions:
DrawCircle, DrawEllipse. The autodocs are in this directory.
graphicsadded AreaEllipse,AreaCircle
Theinterface to Circle and Ellipse had to be changed.
Circleis now just a macro that uses Ellipse.
Ellipseno longer takes a rectangle but takes a center and
2radii.
Fixed MoveSprite to position sprite correctly instead of off by 1
inx.
Copperlist generation addition. If interlaced view, and interrupts
goaway for some reason, the copperlists will ping pong back
andforth themselves.
MrgCopnow about 20% faster. Hope that helps. Depends on instruction
mix
andnumber of actual copper lists involved.
Housekeeping
This release of kickstart will have library version number 33. Use

Intutionnotes:
newintuition.h definition
#defineSTDSCREENHEIGHT -1
Includedwith this document are copies of any changed graphics
includefile plus sample program dotty.c These will also be provided
ona separate disk. Dotty.c can be expanded to use 256 line display.
Thereis a copy of the new trackdisk driver documentation.
Thereis a copy of the source for the animated pointer that Jim had
atthe UK Amiga conference. It demonstrates several basic and
advancedIntuition programming techniques, including pointer animation.
This is the first release with an intuition that jim ripped apart
and
isstill in the process of putting back together. It is included
instead
ofthe older more stable version because it represents the real future
offurther distributions. It significantly uses the new semaphore
technology.Work is also being done on fine tuning the seemingly
redundantrefreshing of the gadgets. Note the cleaner open windows.
Someitems that are still being worked on: the Titles of windows
andthe menu bar get a little trashy. Intuition is starting to using
theclipping of the layer library to avoid flashing the gadgets
needlessly.
Otheritems:
fromjimm (Jim Mackraz) on intuition
Intuition 124
-screen personal rastport now cloned, not corrupted, for intuition
rendering including gadgets, borders, titles, drag/size frame,
...
should solve gadget crashes (while windows are opening, gadgets
refreshing, etc.)
-more locking refinements (not perfect yet)
-screen may be created behind other screens (see flag in
intuition.h)
-screen gadgets may be specified as invisible (see flag in
intuition.h)
-border updates visually improved: rendered through damage list,
only the title and dragbar are redrawn when window made active.
(known bug: title can overwrite depth gadgets)
-border area added to damage list for smart refresh windows, fixes
major bug. updating of border areas still needs refinement.
-clean up and compaction (in some areas)
-pressing menu key with active string gadget deactivates gadget
and
proceeds with menu processing (more like select button now).
newintuition.h included on disk

alpha-4release of kickstart 1.2
comments:
strap:
did not remove the open of intuition in strap, sorry fella's
I'll shoot for alpha-5
intuition:
jimm has got a bunch of bug fixin going on here:
Intuition 161
Size: 54348 bytes (increase 348)
more improvement to window border refreshing
fix bug: gimmezerozero and backdrop didn't work together
(confusion from CreateUpfrontLayer())
OpenWindow() does position/dimension checking (max's only)
incorporated serial preferenes into intuition.h, intuition.i
fixed bug where GetPrefs might copy data in areas beyond
the limit of the buffer the callers provides.
known change in side-effects Boing! has depended on (probably
not new with this particular release).
Plan is to fix the above using new function RefreshOneGadget(),
(actually, something more like RefreshNGadgets()) which, along
with AddGList(), represents the most asked for gadget
enhancements.)
stay tuned
intuitionchanges:
Intuition 183 -- diagonal draggers
New user functions:
RefreshGList (J0002)
AddGList (K0025)
RemoveGList (K0025) (needs testing)
ActivateWindow (J0010) (needs testing)
RefreshWindowFrame (for rj) (needs testing)
see autodocs attached below
fixed top border gadets, including depth gadgets being
overwritten, user top border gadgets work better (J0019)
experiment with drag gadget rendering (will try again)
pointer reset in closewindow, safer (J0013)
modifyIDCMP restores from NULL safely (K0142)
drawImageGrunt safe when out of memory now (J0018)
Enhancement request for keyboard movement of mouse (E1907)
moved to "Wait" list
Changes to menu short-cut key handling. These are so that
if
MENUVERIFY is in effect, applications always know when the
menu handling period is over.
when menuverify is in effect, and canceled, users
now get a message: menupick (MENUNULL)
when the key corresponds to a disabled item, users
now get a message: menupick (MENUNULL) (B2360)
note that if the user cancels menuverify when the mouse menu
button is pressed, application hears a MOUSEBUTTONS:MENUUP
message
Furthermore: menu shortcuts are prevented when normal menu
operations are in progress, and when requesters are up (the
latter was reported
as a bug, but was in place and working fine.) (B2295)
Internal:
removed unused parameters from drawWGadgets
windows.c gadgets.c
consolidated linked list handling; more to come
intuition195:
fixed the propgadget in GZZ window bug
Container clicking at bottom of G00 border propgadgets works now
(un-listed bug?)
Alerts now push down interlaced screens correctly.
ReportMouse() no longer crashes (was error in asm to C interface).
DELTAMOUSE IDCMP now works
intuition:
Intuition 215
NEWPREFS IDCMP works, for the first time ever.
It turns out that you would only get the NEWPREFS IDCMP message
if your idcmp flags contained at least one of: NEWSIZE,
REFRESHWINDOWS, or MOUSEBUTTONS. Note that you would still receive
the proper NEWPREFS message class.
SELECTED gadget flag set when window/screen draggers are in use.
Trying some more drag bar rendering, this time the bars are a
little thicker, and there is some space following the title
OnMenu() and OffMenu() would crash trying to redraw a currently
displayed menu element in Notepad. Now they block until user
finishes with menu.
Sizing, dragging, and menu use while windows are opened/closed,
no longer deadlocks, poof.
not compiling with speed optimizer, saves many bytes
more general linked list handling
routines dealing with viewports all changed around to set
View.Modes correctly at the correct time. visible and hidden
interlaced screens now effect the display correctly. (K0121)
It is verified that Intuition will handle a linked list of events,
providing it is no more than 10 in length, enhancement to this
is
on the list. This is not true if a string gadget is active, in
which case all but the last event (or two) is discarded.
Barry has determined that repeated WRITEEVENTS to the input device
are the best way to fool intuition.
It was determined that string gadgets and GRELWIDTH do not work
together; changing this would require major surgery. moved to
the
Wait list.
Bug B2199 where too many CLI's crashes the machine not reproducible
by JonF
Bug B2214, string gadgets with small buffers cannot be reproduced
by Barry
intuition290:
ModifyProp only refreshes one gadget
On/OffGadget only refreshes one gadget
locking improved: very near to betting that it can't be
deadlocked.
proportional gadgets, especially those with small body field,
now click according to your body settings, and are not dependent
on the resolution of the rendering. very specific formulas for
using propgadgets now apply, and will follow.
propgadgets in the various gimmezerozero and requester layer
environments now container click correctly.
steps have been taken to handle low-memory especially in menus,
and TmpRas' have been set up to help text, but sufficiently tough
memory situations crash in text/graphics.
dale fixed the wild pointer bug. off my list.
fonts supplied to OpenScreen are checked for success in opening.
failure will cause the current system default font to be used.
finally put interface to RefreshGList, AddGList, RemoveGList,
ActivateWindow, and RefreshWindowFrame into amiga.lib
intuition300/301:
doesn't trim DHeight for front screen.
duplicate mouse-move events eliminated for RMBTRAP users
windows which don't come up active don't block behind lock
held when string/prop gadgets are active
all relative gadgets entered into damage list when window sized.
put requesters in smart layers so user-rendering is
preserved.
intuition:
gadgets week.
unified gadgetRelatvity calculations: no more weird proportional
gadget rendering, gadgets locking and rendering calculations done
all in one place. saved 1400 bytes, for a while anyway.
hitting gadgets (Select mouse button) more sane: only checks
correct layer, smarter for requesters in layers now.
string gadgets:
-bug with long gadgets centered in select box shorter than max
string length fixed.
-new feature: click in string gadget puts cursor at click location.
-control-H serves as backspace
-cursor doesn't flash when you push shift, control keys, etc.
and doesn't flash on upstrokes.
-note: centered string gadgets of buffer length 1 (plus one for
null) still don't work (from 1.1). i don't know WHAT is going
on.
changed the Workbench Screen default title back to official name
fixed memory leakage problem in intuition that appeared in a-9.
there is now a minimum limit to the rendering of
an AUTOKNOB, per the manual, but different from 1.1.
am postponing final decision.
intuition378:
=== NOTE: the items below haven't been thoroughly tested ==
New function ActivateGadget() activates a string gadget,
god-willing.
POINTREL requesters now implemented (can have double-mouse
requesters come up at or near cursor position).
===========================================================
Implemented NOISYREQ option for requesters. If NOISYREQ flag
is set, requester being active won't filter normal input--in
particular, keystrokes.
Used above to implement keyboard equivalents for Cancel and Retry
gadgets in system requesters (AutoRequests). Today, these keys
are leftA-V and leftA-B, subject to change.
damage list problems were in layers: fixed by dale.
Now do WaitBlit() before freeing bitmaps in CloseScreen()
and after menus are erased (dale's recommendation). This
fixed Emacs, and god-only-knows what else. This could be a big
one; thanks dale.
caught failing error handling path in requesters. thanks, sam.
unified double mouse requesters and normal, user scheduled
requesters
Intuition 417
AutoDocs all fixed up.
String Gadget fixes:
single-character centered string gadgets had about 3 bugs
in
them: finally fixed after at least 8 hours work. incredible.
RELWIDTH string gadgets should work now; haven't tested.
SetMenuStrip() returns TRUE, which, it is hoped, solves beaucoup
backwards compatibility problems with wrong-written programs (still
need to hear definitive word on what dpaint expects: haven't tested
dpaint.)
WorkBenchToFront/Back() now return success as has been documented,
but not implemented (probably always returned TRUE).
Intuition 454 (+/-1)
Old bug fixes: can use leftamiga-M,N for menu shortcuts.
Fixes to alpha releases: RELVERIFY GADGHIMAGE gadgets work again.
title bar cleared with NULL fill pattern for sure now.
screen being opened while user drags windows will block until
user is done.
old Boing!s work nice again.
ActivateGadgets() and ActivateWindow() all tested and ready
to use.
----
System Requester (in fact all autorequests) will cause the screen
on which they occur to be moved to the front.
----
Masked gadgets now implemented. Use BOOLEXTEND flag in gadgets
flag, see structure BoolInfo in intuition.h.
example forthcoming.
----
Slight change to meaning of IDCMPFlags REQSET and REQCLEAR. Manual
states that they are only sent when first/last of possibly several
requesters is started/ended. This hasn't been exactly true, and
the distinction to first/last is not critical since requesters
are
in layers. Now if you want to be in the ActivateGadget() business,
it is important to know when a requester becomes active, so
* REQSET and REQCLEAR messages will be sent WHENEVER a
requester
* starts or ends (if you have these bits set in your
IDCMPFlags,
* of course).
Programs possibly affected will be very rare, if any:
if a program uses two requesters simultaneously, and the second
one
started is a Double-Menu Request (DMR) (or the first removed),
a
REQSET (or REQCLEAR) message will now be sent where there would
be
none in 1.1.
Further, such a program would also need to be using REQSET and
REQCLEAR as an intimate part of its state machine for problems
to
arise.
----
Menu Verify (and Size and Request Verify) deadlock protection
is
installed.
It is now safe to turn off MenuVerify using ModifyIDCMP().
You must do such a thing before, for example, calling
AutoRequest().
Closing a window is now also safe: no need to turn off verify
first.
Set/ClearMenuStrip() are also now safe. ----
Functions LockIBase() and UnlockIBase() now functional, operate
as documented in intuitionbase.h. More proper documentation has
been added as an autodoc (function header).
Note that one passes a zero to LockIBase in D0. It will return
a
ULONG in D0. Pass that value to UnlockIBase(). Sorry, but you
must pass it to UnlockIBase() in A0, not D0.
For those not wise to these gems, they access the
SignalSemaphore(s) intuition uses to arbitrate its data structures
and state.
If you use (by which I mean READ) the structure IntuitionBase
defined in intuitionbase.h/i and located at the address returned
by OpenLibrary("intuition.library",..) the values and linked lists
that you find may not stay valid unless you protect yourself
against the rest of Intuition. Now, even though you had better
READ ONLY, the Intuition locks are all write locks, so Intuition
Will Freeze while you hold these locks. So be quick, ladies and
gents.
The intent of allowing access to IntuitionBase at all is intended
to provide knowledge of the ActiveWindow, front-to-back linked
list
of Screens, mouse position and little else. More of IntuitionBase
might be made public, for instructional purposes perhaps, but
creative and tricky use of internal data structures will prove
hard
to support.
----
MENUTOGGLE once again operational. apologies for not being able
to find the bug which kept this out of 1.1. (But it was weird.)
Set this flag in a CHECKIT menu item and it can be selected to
turn the checkmark off.
----
punted on attempt to keep submenus from flashing when you
roll the mouse off of a subitem. recommendation: don't leave
any space between your adjacent menu or submenu items.
----
POINTREL requesters really work, as documented in the Intuition
manual. They are constrained to coming up within the window
interior, although programmers can get Requesters to come up
overlapping some borders. POINTREL only applies to Double-Menu
requesters (DMR's).
----
Workbench interlace test of LaceWB preferences restricts to
the LACEWB bit, cause one never knows when y'all run out
of bits, do one?
----
Borderless windows with system gadgets have their "title bars"
refreshed compatibly with 1.1. (not when activated, but when
window layer is damaged.) I think the state of this is
questionable, but Boing!, for one, depends on the old algorithms.
----
intuition.h has added preferences: LaceWB was in, i guess, but
new printer file item now in.
intuition.i and intuitionbase.i are now usable, thanks to Barry.
Intuition 461/7
InstallClipRegion() support added. see layers release for
details.
Might I add that InstallClipRegion() is the breakthrough we layer
fans have been waiting for. (No need for GIMMEZEROZERO).
Math
mathffp:
Supports Ceil,Floor
Serial/ParallelDevices
newserial and parallel device
MARK/SPACEsupported by serial device.
Trackdisk
Thedocumentation for trackdisk driver is now on the disk
seetrackdisk.doc
trackdisk:
actual step rate now down to 3.6msec. The specs for fine
tuningthis
are in this directory. look at trackdisk.h
See tdu_StepDelay,tdu_SettleDelay.
These parameters are extremely hardware dependant! This
means that values that may work for a 68000 may not work
fora
68010 as well as a 68020 or a faster clock, etc. If you decide
the ^[ ^] keys do not generate correct ascii codes.
thatyou must play with this the be aware of the consequences.
trackdisk:
timing problem with 68020 and new external disk drives fixed.
Workbench
workbench/dosleft disk icons laying around when disk has been
removedand there are no drawers open on it. Now fixed.
clickingdisk icon when disk not in used to blow up. Now fixed.
wb: fixed cross disk copy icon bug.
Workbenchdied a horrible death after being closed and then reopened
(e.g.after Graphicraft, tutor, etc.). Now fixed.
Workbench arranges to have it's autorequest messages be marked with
its
name("Workbench") in the title bar. This is harder than it sounds.

The new format command replaces both format and initialize, too bad
our dos does not support 'links'
NOTE:that if you use initialize with the same parameters as you used
Format, it will do something different. It puts a trashcan icon on
the
diskinstead of leaving it blank. SO if you must have a blank

newinitialize/format
Thisis the first V1.2 initialize. It replaces both initialize and
formatbecause it can also run from CLI.
It can initialize any type of disk - even partitions
If you have your SYS: disk in any drive it will use your
trashcan image for the new trashcan. Otherwise it defaults
to
the new trashcan image from WC.
For compatability with the format I've added a NOICON option
to
make completely blank disks.
The motor light stays on during the entire initialization
to
prevent confusion.
CTRL-C stops initialize from the cli (more civilized then
pulling the disk out)
This new command replaces both format and initialize, too bad
