I had my machine running through following
TOS-boot tester configuration combinations
whole day:
  --disks floppy,gemdos,acsi,ide,scsi
  --graphics mono,rgb,vga,vdi1,vdi2,vdi4
  --machines st,megast,ste,megaste,tt,falcon
  --memsizes 2,4,8,14
  --ttrams 0,32
  --bool --compatible,--mmu

With all TOS, and EmuTOS version.  For TOS,
I tested both US & non-US variants, for
EmuTOS I tested only UK one.

This was done with the fast boot options enabled:
	--fast-forward
	--fast-boot
	--fastfdc
	--timer-d

All EmuTOS variants passed all tests without
timeouts.

Some TOS combinations failed, which I'll check
closer to see whether I just need to increase
tester timeouts slightly (except for one fail,
all of them were with TOS v3.06 + MMU, none with
TOS v3.00 + MMU).

After that I'll do some runs without fast boot
options (with much reduced set of HW combinations
to keep runtime within 1 day).
