<p>this one is just weird</p> <p><b>New page</b></p><div>[[Category:83Plus:BCALLs:By Name:Other|MarkOSInvalid]] [[Category:83Plus:BCALLs:By Name|MarkOSInvalid]] [[Category:83Plus:BCALLs:By Address|8093 - MarkOSInvalid]]<br /> == Synopsis ==<br /> '''Unofficial Name:''' MarkOSInvalid<br /> <br /> '''BCALL Address:''' 8093<br /> <br /> Set bit 0 of certificate byte 1FE0h, which indicates that the OS has not been successfully validated.<br /> <br /> === Inputs ===<br /> ''None''<br /> <br /> === Outputs ===<br /> ''None''<br /> <br /> === Destroys ===<br /> * AF<br /> * [[83Plus:RAM:8478|OP1]], [[83Plus:RAM:82A5|tempSwapArea]], [[83Plus:RAM:8100|ramCode]]<br /> <br /> == Comments ==<br /> Flash must be [[83Plus:Ports:14|write enabled]] first.<br /> <br /> This routine copies all of the certificate data from one sector to the other while setting the appropriate bit, and finally erases the original certificate sector.<br /> <br /> The reason for making this a B_CALL is not clear to me.</div>
