Hi Vlad,

On startup, the Memory Manager marks the following regions as
reserved:
- $00/0000 to $00/07FF
- $00/C000 to $01/07FF
- $01/C000 to $01/FFFF
- First unused bank ($80/0000 on a 8 MB IIgs) to $E0/1FFF
- Lots of memory space on bank $E0
- $E0/C000 to $E1/1FFF
- $E1/C000 to $FF/FFFF

The second text page is not protected on banks $00 and $01...
