Quick question regarding S/G I/O

[SA1988]

I tried searching for hours where it is on PCem's code, I think it is absent from it, if anyone has managed to find some piece there, where is it? Thanks

What do you mean by S/G - scatter/gather? If so then there isn't a standard implementation in PCem as there's no standard for it on the PC. The closest you'll find is the DMA code for the PIIX IDE interface.
