[Coco] Interbank Incident for Drivewire

[Luis Antoniosi (CoCoDemus)]

Robert,

I can't make IBI work from the superIDE. I got your fix, I have now 152 + 1
pages free and I still get a error #207

I have:

REL Krn KrnP2 Init Boot IOMan RBF RBSuper llide IH dd SCF VTIO CoVDG Term
Clock Clock2 SysGo Shell.

Is anything else I can do to free more space ? How many pages does this
program need ?

Thxs,
