HI, just come across this, my 460 came prebuilt from AmigaKit as well, i typed the same command in and this is what came back.

*** Error opening device sii3114ide.device / unit 1
-------------------Unit 2 information------------------------
Flags : $00000187 - present, LBA48 used, supports DMA, ATA, supports cache flush, interrupts used,
Xfer mode : best pio 12 (PIO 4, 16 MB/s) / best dma 70 (UDMA 6, 133 MB/s) / current 12 (PIO 4, 16 MB/s)

Blocksize : 512
Power mode : 2 / idle (ready for operation)
IO1 / IO2 / BMCR @ : $1010 / $101A / $1028
I take it that means my devices are running in pio mode as well ?.
And just to double check i type need to type the same command in as above ?.

Sorry if the above sounds dumb but I've only had the 460 about 3 weeks and dont want to stuff it up already :)

You are correct either type this in a shell to leave optical drive in best PIO mode (arguably more correct)

NVSetVar sii3114ide_xfer 0GGG

or type this in a shell

NVSetVar sii3114ide_xfer GGGG
