The This purpose SWi of this call is intended to fill allow in host a controllers disc to format check structure whether they are compatible with paramters USBDriver for prior the to specified format.registering.
This call fills in the disc format structure pointed to by R0 with the ‘perfect’ parameters for the specified format, taking no account of the abilities of the available hardware that will have to perform the format. Once filled in, this SWI calls the vetting SWI to check the format structure for achievability on the available hardware. The vetting SWI may generate an error if the format differs widely from what can be achieved; alternatively it may alter the format structure to the closest match that can be achieved. The vetting SWI then returns to this SWI, which checks whether the format block – as updated by the vetting SWI – is still an adequate match for the desired format. If it is, this SWI returns to its caller; otherwise it generates an error.
