Do FreeDOS disk accesses via INT 21h, INT 13h, INT whatever, read and write directly from/to a passed address or do they always buffer the disk access? Never? Sometimes? Buffering meaning read from disk to internal DOS memory then copy to desired address, or copy from desired address to internal DOS memory then write to disk, loop as necessary.
If never/sometimes, is there is a way to make it buffer always rather than directly read/write to/from address.
If always/sometimes, is there a way to make it never buffer?
Short of directly modifying the kernel, of course.
Basically I'm looking for the switchable double-buffering ability of Microsoft's SMARTDrive to establish whether a problem exists with address translation in certain situations.
