california access malibu boot rom

[roy bates]

as in title i can dump the bootrom for this device,while i still have the machine here for repair

apparently its needed?


let me know and ill dump it through my programmer its only about 8k


ill need to know quick as itll be due to go back next week,i cant remember where i read it,i think it was winuae website?

[Toni Wilen]

Yes, please! Any Amiga expansion ROM/EPROM should be always dumped, even if it seems useless

EDIT: Could you also take photo of the board?

[roy bates]

okie dokie ill dump the bootrom in a minute

give me a few minutes to pull the card and compact the file and dump it in the zone

[Toni Wilen]

And one more thing: output from WB2.x+ "tools/showconfig debug", thanks.

[roy bates]

its in the zone


ill have a look at that in a sec tony

[roy bates]

excuse my ignorance but where is that exactly?

[Toni Wilen]

What is where? showconfig? It is located on WB disk (sys:tools/showconfig) Type "sys:tools/showconfig debug >output.txt" in shell.

If you need 1.x compatible program, use this: http://www.winuae.net/files/b/expdump.zip

[roy bates]

ill try that later

i seen your edit,its the same board in the big book of amiga hardware,so im not sure sure a picture of the board is needed

this machine is under 2.04 i think

i was trying to find showconfig but couldnt find it

[Toni Wilen]

Yes, that photo was good enough. I only needed to know which SCSI chip it uses. (It was usual 5380)

Auotoconfig dump (via showconfig or expdump, unfortunately most other system info programs don't list the boot rom vector offset) is needed to know the exact address of boot ROM.

EDIT: Showconfig is located at least on 2.1 and 3.1 Extras disk (not WB). It does not seem to be included with 2.0.

[roy bates]

yes, it does use a 5380


ill see if i can have a look later tony,and try to report back

Unfortunately not, that information can be easily found. The other not shown bits are the important part, it requires "showconfig debug" or above expdump.

[roy bates]

ok ill try again

is there a way to do this from floppy? ill give it a go if there is a way

i cant mess with the harddrive,i have instructions to leave that be

EDIT: if there is a way to drop it into the harddrive and run it,ill do that,i can remove it afterwards

EDIT2: hang on i have an idea

[roy bates]

ok i got it give me a while to type it out

[Toni Wilen]

You mean the expdump output? Only the 16 byte hex string is needed, you can ignore all the other lines.

===========================================


is that enough info tony?

[Toni Wilen]

Yes, that is exactly what I needed, thanks! (InitDiagVec was the most important)

EDIT: if you aren't too bored yet, could you check if any value changes when controller is in non-autoboot mode? D1 may change to C1 or er_InitDiagVec may change. Others probably stay the same.

[roy bates]

ill have a look in a bit im having a cuppa

you mean physically setting the card to not autoboot via its jumper?

Yes, switch off autoboot using the jumper, then boot from disk and see if either er_initdiagvec or er_type has changed (or if nothing has changed)

[roy bates]

yes,D1 does indeed change to C1

er_InitDiagVec doesnt change
