40 *
41 * Went back to the 1MB limit, as some people had problems with the floppy
42 * driver otherwise. It doesn't matter much for performance anyway, as most
43 * floppy accesses go through the track buffer.
44 *
45 * On MIPSes using vdma, this actually means that *all* transfers go thru
46 * the * track buffer since 0x1000000 is always smaller than KSEG0/1.
47 * Actually this needs to be a bit more complicated since the so much different
48 * hardware available with MIPS CPUs ...
