Ah ha, Ken, it=B4s not.
Sorry for misinformation. I took it from a log of my daily configuration.

I have RAM Doubler but I boot without (and extensions too). The booter says
no when trying to boot with.

The trouble is on Debugging level >0

With this configuration:

Debugging level - 0
Extradebugging info - checked
No env dumps - checked

I=B4m coming :-)

Last words before leaving MacOS:
Set _mac68k_vrsrc_cnt to 0x0

Then boots right.

Anyway, lot of thanks for replying to a newbie.

See you.
