Red then blue screen when booting OS4 Classic from CD

[A4000_Mad]

Hi moto,

It's been a while since I played with OS4 and I don't have a CDrom on my A4000/PPC at the mo.

I can't answer the question above but IIRC it's just the same as booting into your Emergency-Boot floppy and OS3.9 CD.

I've just booted into the A4000/PPC using OS4 boot floppy disk only and got the report "Please insert volume AmigaOS4.0 install CD in any drive".

(I didn't see any flashing colours)

I then stuck the OS4 boot floppy disk into my A4000/060 and go the same "Please insert volume AmigaOS4.0 install CD in any drive". Inserted the OS4 CD but it wasn't found because my CDrom is unit 2 on the secondary IDE channel......Doh! (no flashing colours were seen)

Took the floppy out and did a reset forgetting that I was running the prog called CD-Boot. I chose to boot into the OS4 CD and got:-

C:BootLoader: Unknown command
C:BootLoader failed returncode 10


IIRC correctly the fact that you are seeing the flashing coulours is a good indication that the OS4 CD is being found ok. If you remove the OS4 CD and just boot from the OS4 boot floppy, do you see "Please insert volume AmigaOS4.0 install CD in any drive"??

(It's rather fitting that my 1000th post should be for you mate ;-) :pint:)

I'm pretty sure that as an experiment I removed my GFX card and the installer displayed AGA no problem. IIRC the installer looks for supported GFX cards and displays in 800 x 600 for you :-)

Further to my first post in your thread, I've amused myself by putting the file 'IDEfix' into the C drawer of the OS4 boot floppy disk. I then made the top of the floppys startup-sequence read like this:-

C:Assign T: Ram:
If exist C:IDEfix
C:IDEfix
EndIf
set MACHINE 'checkA4K'


After booting into the floppy my OS4 CD was then found as unit 2 on the secondary channel of my 4 way interface.

Just thought I'd share that with you :-D

Erm..... As stated in my previous I was experimenting using my A4000/060 as I don't have a CDrom on my A4000/PPC at the mo :oops:

I believe a prog called Scout told me the speed of mine, but I'll check when I get the chance for you.

[A4000_Mad]

Scout confirmed as after launching it and clicking on 'System' I'm seeing "PPC: 604e / 233Mhz"

I'm not running OS4 at the mo but it's worth giving it a try mate :-)

It appears that if you fully boot into OS4, do a warm reset and then hold both down both mouse buttons, you get some additional information at the 'Amiga Early Startup Control' screen.

Mine says:-

CPU: 604e V9.516 231 Mhz
L1 cache: 32K, L2 cache 0K
Memory: 64MB Frequency: 66 Mhz

The speed will be relevant to your question. It reminds me that I need to put in some more memory, as I've only got 22MB left after booting into OS4 :-)

I've been meaning to have a look at the new Early Startup screen, and I'm also curious to know what "Boot with no s-s" looks like now. I'll have another play later :-)

Actually, I haven't seen any new one. It's the same old one, but if you do the warm reset while keeping both mouse buttons held down, it has more info on the screen. I think it's probably just to do with the CSPPC being present as it happens when running OS3.1 with WarpOS too.

"Boot with no s-s" doesn't look any different either. In fact, when I use it with the Ultra Wide SCSI drive connected to the CSPPC, all commands appear to be not executable.

How do you get to see it Framiga? (if I switch on while keeping both mouse buttons held down, I just see that usual 'Amiga Early Startup Control' screen)

[A4000_Mad]

Thanks for that Framiga :pint:

So, what I said below was correct:-

It appears that if you fully boot into OS4, do a warm reset and then hold both down both mouse buttons, you get some additional information at the 'Amiga Early Startup Control' screen.  Mine says:-  CPU: 604e V9.516 231 Mhz L1 cache: 32K, L2 cache 0K Memory: 64MB Frequency: 66 Mhz

I just needed to click on 'Boot With No Startup-Sequence' after doing it. Now the commands are working fine  8-)

with CTRL+ALT+ALT you can cold reboot (useful to switch between different OSs)

Thanks again. Because of that I might go for an OS3.9 and OS4 dual-boot system :-)
