[GetBank]

Specifies the name of the function to be called in order to get the 
current write bank. This assumes a device with an aperture smaller than 
the PageLength. The bank number is assumed to be returned in r0. It should 
be sensitive to the mode. 

Here is a sample .PMI file for a 9GXE S3 card: 

[GetBank]
inb(r1, 0x3d4);          //save index
outb(0x3d4, 0x35);
inb(r0, 0x3d5);
r0   & = 0x0000000f;
outb(0x3d4, 0x51);
inb(r2, 0x3d5);
r2   & = 0x00000004;
r2   <<= 0x00000002;
r0   |= r2  ;            //r0 contains the value
outb(0x3d4, r1);         //restore index
