Yes. > Can we un-deprecate IDENTIFY DEVICE DMA? Thoughts ... 1) A con is the debate over how dangerous and how in violation of past specs is the idea of issuing reserved/ obsolete/ vendor-specific/ etc. ops, now unresolved in "Re: [t13] Feature Negotiation policy question". 2) A con is that practically speaking we cannot dream up some new positive PIO-free way of saying that op is supported, such as changing the reset signature. 3) A con is to ask what's keeping you now from trying that op, using it if it works, and then resorting to xEC/A1 IDENTIFY only if it doesn't work? Why will those reasons not apply if a .pdf appears at t13.org saying you may try that op? Or if you are trying that op, what will a new .pdf at t13.org buy you? Pat LaVarre
