BasicDiag - bootblock diagnostic program

[RomanWorkshop]

Hello, I want to present my bootblock diagnostic program that is checking basic hardware parts of every Amiga, equipped with floppy drive. It is recognising CPU 680x0 model (in case of 68060 also it's version: "68060" - full, "XX060" - EC/LC and revision "(rev X)"), FPU model (68881/68882/IN040/IN060), graphics chipset (OCS/ECS/AGA) and it's standard (PAL/NTSC), Kickstart version from 1.2 (33.166) to 3.1 (40.72). Older Kickstarts (0.7 beta, 1.0, 1.1) will be recognised as "Kickstart 1.x (xx.x)" and newer (43+) as "Kickstart 3.x (ver.rev)". Kickstart 3.5 (40.71) will be detected as "Kickstart 3.1 (40.71)". Also amount of available free CHIP and FAST memory (in "kB") is displaying.

All code is written in assembler (I'm using my own detection routines) and current size of diagnostic bootblock is 988 bytes.

just tested a bit and found an issue with A1000 OCS kickstart 1.0.
see image attached.
other quickstart (winuae) configs give good rsults

#1) oh, kicks 1.2+ only?

[RomanWorkshop]

Thats why it is Kickstart 1.2+ program Reason of this is simple: older Kickstarts (0.7b, 1.0 and 1.1) have $FFFF (65535) values at address $F8000C (version) and $F8000E (revision).

ok, ic, something learned

Works fine on A4000/040 KS39.
BTW, you can save 10 (or 8, if you have to preserve d2) bytes in the $f8000c/$f8000e code by using subs instead of cmps:
moveq #33,d1
sub.w d1,d2
...
subq.w #34-33,d2
...
subq.w #36-34,d2
...
subq.w #37-36,d2
...
subq.w #39-37,d2
...

Maybe I will show each detection routine separately (Polish comments):

ChkCPU, Chk060, ChkFPU, ChkGFX, ChkKS.

[RomanWorkshop]

I was improved Kickstart version check routine. Now versions older than 1.2 are recognized as "Kickstart 1.x (xx.x)". Kickstart 3.5 (40.71) will be recognized as "Kickstart 3.1 (40.71)". Kickstarts newer than 3.1 (40.72) will be recognized as "Kickstart 3.x".

Program now should run on every Amiga with floppy drive. Complete source code (with Polish comments) and ADF image can be downloaded from here: BasicDiag (Polish website: link).

I addeded displaying amount of available free CHIP and FAST memory (in "kB"). Size of program is now 928 bytes.

Nice!

May I ask how you detect the ram?

[RomanWorkshop]

I'm using "AvailMem" function from Exec, which returning number of free bytes of selected memory type. Next I'm dividing this value by 1024 and I get memory size in "kB".

In new version of BasicDiag 1.05 (988 bytes), I added detection of pressing mouse buttons. When you press left mouse button (LMB), Amiga continues booting from floppy (startup CLI is showing up). When you press right mouse button (RMB), Amiga is reseting.
