Could you check "DOS31_original" file? If this version don't works then perhaps dos library can't be loaded via current version of LoadModule or older OS like OS 3.0 can be necessary.

"DOS31_original" also does not finish booting. Your new version boots into Workbench but has strange issues afterwards. I had trouble with CygnusEd (v 4.17). Two times it could not start - it tried to open the CED-screen but failed several times. Another time it opened a CED-window instead of a screen, a third time the Amiga crashed with some graphcs corruption before:

Thanks for tests. If DOS31_original version don't works on your config that dos library can't be replaced via LoadModule, due this is original (only relocated) version of DOS 40.3 from A600/A1200/A4000 3.1 ROMs, perhaps custom ROM must be created. DOS31_new can be buggy (my buggs), but it has also not removed one more code protection.

Resourcing code and understanding the code are two different things for me. Especialy code written in C, anyway I started to find and optimise dos routines one after one. Here is the one of the shortest, maybe useful for someone:

; SYNOPSIS
; status = IsInteractive( file )
; D0 D1
;
; BOOL IsInteractive(BPTR)

lbC0222DA ; _LVOIsInteractive
; MOVE.L D7,-(SP)
; MOVE.L D1,D7
; MOVE.L D7,D0
; ASL.L #2,D0
; MOVEA.L D0,A0
; MOVE.L (4,A0),D1
; MOVE.L D1,D0
; MOVE.L (SP)+,D7

asl.l #2,D1
move.l D1,A0
move.l 4(A0),D0

RTS

I did not load it via LoadModule, already built custom ROMs for testing. Not much of a hassle with Remus.

Then perhaps it must be Remus bug or you made something wrong, due both versions are identical (except absolute addres values). Attached is compare table, if someone want to check.

PeterK · 22 July 2011, 12:52

I've tested Dos31_original with LoadResident from the startup-sequence and also with Remus replacing only the dos.library in Kickstart 40.68 and both works on my WinUAE system.

_mandark_ should try a custom ROM with the dos.library 40.3 and the SHORT RELOCs !

I can do that if you tell me how to.

I didn't find a Remus setting concerning RELOCs, only found some utilities on Aminet by using it as a search term. Apart from that I got no further clue...

I think the ROM is fine, as it worked for building my custom OS 3.9 BB3 ROM and ROMs including Cosmos Betas. So it should not be complete trash. But I also tend to make mistakes from time to time

This is the .rpf which I used for building the custom ROM. "dos.library_orig" is the resourced version from Don_Adan:
os39_db.txt

PeterK · 22 July 2011, 19:38

The dos.library 40.3 with the SHORT RELOCs is that which belongs to the original Amiga Kickstart ROMs.

Unfortunately, Don_Adan has given his modified version with the RELOC32 tables the suffix "original". That can only cause confusion.

Just take the dos.library 40.3 with the size of 40132 bytes, CRC32 2F69D3EB, MD5 E278804F80DC9A9B3015B680C504A758.

properly resourced I would expect:
...
move.l (fh_Interactive,a0),d1
...

BTW, I do not see that much sense in doing this, but if you do it anyway you could also made a variant for 68020+:

move.l (fh_Interactive,d1.l*4),d0

Sorry, in the current archive there is no such file:

Please use RomSplit to extract the true original dos.library 40.3 from your ROM.

Well, the original library from my 3.1 Kickstart ROM of course works, if I use it in my custom ROM. With the same .prf otherwise.

Just gave it another try to verify my findings. My custom ROM with DOS_original is booting fine, everything working as expected! So I must have mixed up something the first time..

Don_Adan · 24 July 2011, 15:15

Next version is available.
One my bug fixed, some original bugs for SetIoErr fixed, some comments added, some routines converted/reworked to ASM (check for "final version").

I think similar, one ROM can be for all 68K CPU's, external OS libraries/devices can be optimised for every CPU's. Perhaps size of ROM fully converted to ASM can be lower than 256 KB.

Amiga ROM's has no relocs or short relocs, due are pure binary file loacted at $F80000 (like ROM 3.1) or $FC0000 (like ROM 1.3) address. Only some parts of Blizzard/Cyberstorm ROMs (located at $F00000) has relocs.

Well, that's good news, of course !!

Edited: SpeedROM comment removed.

@Don_Adan
Yes, you're right, the ROM has no short or long relocs. But your Dos31_original was already the modified version and not the original output from RomSplit.

If it's from your .lzx I downloaded about 10 minutes ago I tested it already

434ad78e4a12c5f326d452e53a9ffe04 DOS31_new, MD5

It still doesn't finish booting. I discovered that this is somehow connected to MCP. If I uncomment patchcontrol and MCP in the startup-sequence the boot process continues - until it complains about Volume C not being mounted. Then C:AddDataTypes, C:IPrefs, C:ConClip, C:FBlit, C:Systempatch cannot be executed and I get dropped into an empty Workbench screen (no Volume icons shown).

This is my startup-sequence for DOS31_new:
startup-sequence.txt

PeterK · 24 July 2011, 16:19

The latest Dos31_new causes a Guru (exec: checksum error) when I try to load it with LoadResident. Please use build-numbers for your new versions.

daxb · 24 July 2011, 18:51

I tested today the new DOS lib (don`t knwo which version). Replaced it with original and made a ROM file with Remus (+romfixes2). The file is loaded with RemAPollo. Result was booting fails with software failure (something witch access to CD).

Don_Adan · 25 July 2011, 11:41

Next version is available.
Next my bug fixed, more routines reworked to ASM or optimised.
