SMUC LBA
ZXNet echo conference «real.speccy»
Quote from ZX-News:
"Each subpartition or disk image can be
connected to driver A, B, C or D. Emulation information is located in the 2nd relative sector, if the Shadow Monitor
does not work in LBA mode, and in 3 relative sector, if the LBA flag is enabled. Its
length is 1 sector. Each disk is described by 22
bytes:"
How to automatically know which sector (2 or 3) needs to be read? That is, how to programmatically find out in what mode (LBA or not) the monitor is working.

The monitor sets what mode the screw is working in, therefore, in what
mode the screw is working, so is the monitor.
However, this statement will be false if there are boots/systems
that will change the operating mode of the screw (for example, to check whether
it works in LBA), then you will need to look for the monitor system variable, but it seems to be in different places in different versions. But such programs will most likely
restore the mode after themselves (unless they are reset ahead of time),
so it’s optimal to just look at what mode the screw is working in.
Stanislav, don’t be bored! WbW, i┌i└/4D.
