Red then blue screen when booting OS4 Classic from CD

[Framiga]

ok, the one i posted is a mirror of the whole AOS4 CD onto my HD (Vuoto:)

So you will use the Start_From_OS3.x script?

[motorollin]

No, there is no OS3.x installed on the drive. Just the contents of the OS4 CD. Think of the hard drive as an exact duplicate of the CD so that the unmodified OS4 floppy can find the files it needs to get to the installer.

looking at the boot floppy SS, it should.

Use absolutely a 500MB bootable partition with a filesystem supporting long filenames. (the CD is less than 150 MB).

All the rest is up to you ;-)

oops remove "bootable"  

[motorollin]

Ok, I'll take the hard drive out of the Amiga, connect it back to my Mac and install SFS from within UAE. Then I'll copy the CD contents on to it and try again. If that doesn't work I'll remove the BVision and see if that works.

gulp, ok! let we know.

[motorollin]

Will do - but not tonight :-)

As i'm a bad guy, i'll tell you to try to install MOS PUP first on a standard FFS partition (make sure that there is not SFS partition), then install the 68k FFS filesystem on the OS4CD and create 2 good partitions, 1st for all the CD content (copy CD0: XXX: all clone), the 2nd for the "system" and modify the startup seq in consequence.
I did something like that in time ...

@CLS2086
Thanks for the suggestion but TBH that sounds more complicated than using UAE to copy the files to the drive. I'll consider your suggestion if that doesn't work though.

Well I have had some success :-D

I re-partitioned the hard drive with SFS and re-copied the OS4 files, but unfortunately it still wouldn't display anything on the VGA monitor. I started thinking that the BVision must be dead, so I removed it. When I booted again, sure enough there was the OS4 installer on an AGA screenmode!

Then I noticed some bare wires coming from the A1200 motherboard, right underneath where the BVision would have been. They were connected to the floppy connector, and my heart sank when I thought of 5v going somewhere they shouldn't. I removed the cable and re-connected the BVision, booted up, and up popped the OS4 installer on my VGA monitor!

:banana: :banana: :banana: :banana: :banana:
:pint: :pint: :pint: :pint: :pint:

Can I assume at this point that the PPC definitely works?

I clicked through the installer (actually just Locale Prefs...) and it seemed very slow, and after the Locale Prefs had closed I was left with a blank Workbench Screen. This might be a weirdness due to the installation files not being located on the CD, so if someone can confirm that the presence of Workbench at all means that the PPC is working then I'll invest some money in this machine and get a 44->40->40 way IDE cable.

Red then blue screen when booting OS4

It's a sign! ;-) :-P

Hi,

take time to check the bppc firmware too !  ;-)

:lol:

Actually, now it's booting it goes red then blue then purple. Since red and blue combine to make purple, I choose to believe that this A1200 is trying to tell us that OS4 and MOS can live in peace and harmony ;-)

I will once I have got the OS installed. But I don't think I can do that without a new IDE cable, and I don't want to buy it until I know the PPC is definitely working ;-)

its working!

OS4 starts using the 68K to load the bootloader (all 68K until now filesystem also) then reboots and since then only the PPC is used.

Now start to reduce every eye candy like gradients and antialias, use a 16 bit WB and enjoy it! :-)

oops forgot ... remove screen dragging and Drag/resize window with contents also. (beeing a 603e without SCSI)

Brilliant!!!!! Thanks!

Well I can't install it yet since my buffered interface seems to be incompatible, so I need to order an IDE cable and then I can install it. Then the fun begins :-)

ok perfect!

Once you have installed the whole AOS4, you can use your buffered interface.

It "seems" that the problem arise only during the installation (on some machines)

Theres a option to enable it.

look at the file SYS:Kickstart/KickLayout-A1200 at the line

; The IDE scsi.device can not autodetect IDEFix/IDEFix97/IDEFix Express
; IDE port doubler hardware. When you have such hardware installed,
; uncomment the following line by removing the leading semicolon,
; then the IDE scsi.device can use IDE drives on the second IDE port.
; CAUTION: Dont forget to add the semicolon again before removing the
; IDEFix or compatible IDE port doubler hardware or your machine may
; not boot anymore!
;
;MODULE Kickstart/A1200/ATAPIismajik

uncomment "MODULE Kickstart/A1200/ATAPIismajik" and it "should" work.
