How to boot '020 A2000 into PAL / '000 mode?

[blakespot]

I recently added an A2060 (68020) to my A2000.  I am in the states and this is a NTSC A2000.

I am trying to find a way to boot floppies into PAL mode under the 68000 (68020 disabled).  I can't seem to get it working with the right click for CPU menu and double click for boot menu, or adding Degrader into the mix.

Can this be done?  God, I hope so.  

HELP!

If the machine has been upgraded to ECS, you should be able to do the boot menu (hold down both mouse buttons while booting up), at least for the PAL part of it

Only with Kickstart 3, I think.

@ blakespot

With Kickstart 2, the rightmost button in Degrader should reboot with your chosen settings reset resident. Are they not surviving the switch into 68000 mode?

How's that?  I have Kickstart 3.1 and 1.3 on a ROM switcher, btw.

Select KICKSTART 3.1 and like runequester write below:

...hold down both mouse buttons while booting up...

In the EarlyStartupControl screen, press a key to toggle between PAL & NTSC.

Selecting PAL in the boot menu seems not to set me to PAL.  Degrader does, but then I'm not in 000 mode.  Hmm.

Does Degrader cause a softboot? If so, have you tried holding down the mouse button to disable the 020 during that boot?

Also, in the early startup menu, are you just hitting spacebar to switch to PAL or actually going into the display menu to pick PAL?  Hitting the spacebar only puts the early startup menu in PAL mode, upon booting past it it switches to whatever mode is selected in the display settings menu, which by default is of course NTSC.

Look for Install Switch on Aminet.  It writes a boot block on disks and makes them boot to PAL.  Do it on a copy first to make sure it does not mess the boot block up.  It works great.  Only needed for disks that need PAL of course, even works on *most* games disks with custom boot blocks!

Doing a right-click to go 000 after the Degrader soft-boot seems to kill the degrader boot -- the screen of consecutive, full colors (with orange at the end, in PAL) do not happen - it just boots up NTSC as if Degrader was not involved. :-(

So did A2500 owners of NTSC machines not watch demos, generally?  Trying the boot block method -- but it seems insane there's no way to boot with 1) 68000 and 2) PAL combined.

I assume I need 68000 as many demos that DID run before I installed the A2620 (68020 accel) are not running on the current system after the typical Degrader boot (for PAL -- and it is going into PAL, as long as I don't go the the CPU menu after the boot).

Crazy frustrating.

Do I need to rig a PAL switch or something, somehow?  Want to get this sorted.

Thanks.

As you got an A2000 with a 68020 CPU then why not try WHDLoad and install KG's demo packs onto your hard drive?

I've only started using WHDLoad recently (on an A4000 with KS3.1 and a 68040) and it certainly seems to do the trick once you installed the correct ROM images onto your hard drive.

Oh, and check which Agnus you have.  I picked up a NTSC ECS A2000 off eBay and using a knife I fixed it to boot into PAL instead of NTSC.  However, this only works with certain mobos with certain Agnus chips.  If you're luck enough to have the right combination then you can even set a switch onto a jumper and toggle which mode to boot into.
