Byte Description
In order to detect the maximum size of writable storage area, your software can
perform a series of read accesses while incrementing the block selector with each
access. Once the error code C9 is returned, the limit has been reached and the total
available space in the writable storage area can be easily determined by the number of
previously performed successful read accesses.
This is supported by HPI, for details refer to the System Management Interface Based on
HPI-B User’s Guide related to your system environment.
