ROM resident HRTMon

Toni Wilen · 27 December 2007, 17:06

(continued from http://eab.abime.net/showthread.php?t=33856)

My (possibly pointless) HRTMon resident rom module works (at least in emulation, real Amiga test "later")

Used Remus to create 256k 0xf00000 extended rom with my hrtmon module only (50k). Decompression and relocation takes about 4 seconds (A500 CE-mode) Level 7 interrupt activates hrtmon as expected.

Todo:
- "emulate" MEMF_REVERSE flag on KS 1.x (done)
- only enable if some fast ram or >0.5M chip ram available? (done)
- disable feature needed? (press mouse or joystick or something during boot?)

I'll post sources soon..

O_O this is fantastic news!
I was talking with Stingray about making HRTMon a part of our custom Up Rough kickstart 2 days ago! Wicked. Is this a coincidence?

Toni Wilen · 28 December 2007, 08:32

I "only" wanted something to fill my CDTV's 1M EPROM. (and semi-hackish 68k coding is still fun!)

This is not my only stupid/crazy idea: I was thinking about compressing some ROM residents (or alternately make ROM image with exec only + one resident that decompress the rest of ROM to RAM..) to get more ROM space..

Unfortunately it is quite pointless (I like pointless stuff..) because it will make booting painfully slow and needs lots of RAM.. (with 68020+ and Fast RAM it could work but why?)

at least 'ROM' HRTMon can be useful..

Source attached. Useless but fun or something..

spoUP · 29 December 2007, 00:33

Wow! Thanks thanks thanks!
Please make more useless kickstart hacks!
This is so cool!

We've made a cool bootlogo, and a bootmenu is in the design phase.

Some kind of gfx/music ripper would be cool. =)

a blizkick module to add copper bars to the early startup screen like copper-deamon does for the WB would kick ass too!

spoUP · 31 December 2007, 01:35

also, having copy/dir etc on the rom would be supa!

spoUP · 01 January 2008, 21:11

BTW... this new source, i need the datafile from hrtmon 2.30 to assemble it?
where do i get that?

thanx!

This hrtmon hack works great in UAE with a 1mb rom i've made that has this HRTMon version included.
I can activate it via an emulated level 7 interrupt at any time.
But when I made a 512k rom with hrtmon included and blizkicked it into my a1200 and used my level 7 button I can only seem to enter HRTmon when an WHDload app is running?
Isn't it supposed to be accessible all the time?

Toni Wilen · 04 January 2008, 21:43

Different setups most likely. Your real Amiga setup most likely have some patch (perhaps even 680x0.library) that moves VBR and also resets level 7 vector.

Does it work if you boot without startup-sequence?

spoUP · 06 January 2008, 17:46

i just tested to boot without startup-sequence, and still no go..
it's equipped with a 060... and i am using pirus exec in my rom. i've removed all blizkick patches.

spoUP · 06 January 2008, 17:54

update: i just created a plain 3.1 kickstart image, and added hrtmon to it, and it still won't get activated.

Toni Wilen · 06 January 2008, 18:59

I am going to try real A1200 test later (Blizzard 1260) but first I am planning something even more weird:

Single-boot KS 1M ROM without blizzard maprom feature (because it only supports 0xf80000-0xffffff area, other ROM areas are filled with "random" ram bank..), perhaps even including compression

Anyway, the point of this hack is to "emulate" 1M maprom-feature without maprom feature. (special code in ROM that puts all residents to fast ram during boot)

spoUP · 06 January 2008, 19:14

maybe something is wrong with my level 7 button...
i just made a kickstart without hrtmon in it...
and loaded hrtmon 2.30. i can enter it with rmb, but not
with my level 7 button..
when i press my level 7 button, my amiga halts, i thought
this was the right behaviour?
if i activate hrtmon with rmb, and then press my level 7 button i get a red bg in hrtmon, i thought this indicated that my button works?

spoUP · 06 January 2008, 19:16

is there any easy way to check that my level7 button actually works?

spoUP · 06 January 2008, 19:31

hmmm now i started the whdload version of Desert Dreams,
with hrtmon 2.30 installed in ram.
i pressed my level 7 button, and i got this error message:

Exception "1" ($7)
at $CED447F9 occured.

So I guess my button works? Or what does this mean?

spoUP · 06 January 2008, 19:33

har har... or maybe not?
now i tried pure metal coders alpha and omega.. pressed the button and got this error message:

Exception "232" ($A3A3)
at $2ECA3A3 occured.

demoniac · 06 January 2008, 22:56

Did you program the address where the exception defaults to? The Level 7 exception address should point to HRTMon's address.
