Hi,
While running TOS bootup tester, I noticed that Hatari has regression
with TOS v2.05 (regardless of TOS language version).
If there's <2MB of ST-RAM and one uses "--fast-boot off" option,
TOS never boots with ST, it just bus errors:
---------------------------------------------------------------------

It works also with MegaSTE, and some STE configs, failure is mainly
with ST:
hatari --fast-boot off -s 1 --machine st --tos tos205de.img
This works fine with Hatari v2.0.0, but doesn't anymore in
Hatari v2.2.1, i.e. it's a regression, a bit old one.
