Wow. Given the amount of things that can be done with audio networking, and or connections via wireless to a CF card, this seems like something that should be considered.
- spacecadet 3y agoWell, they are non-obvious slots near Flight Attendant stations and high traffic areas. I wont say I hung out near them on a flight and observed traffic patterns, nor did I observe periods in the rear of the plane where one CF slot was unattended. I forget the exact model now, but Im leaving out alot of detail. There are assumptions in the "unattended slot" hypothesis. For one, the slots need to be set to an autoplay, which is not a given, and if not- requires navigating a complex and dated touch screen.
- weinzierl 3y agoIf I remember correctly CF was just a stripped down PCMCIA which in principle is capable of DMA.
- ctxc 3y agoQuite the acronym soup, but off I am to Google it...
- ctxc 3y agoAndd I'm back. Got to love when it all comes together :P CF is compact flash card, kind of like the big memory card in cameras. PCMCIA is a PC card whose function is to "introduce peripheral capability to a laptop", kind of an interface. DMA is direct memory access.
- mips_r4300i 3y agoIt does have DMA but this only speeds up data transfer. You are probably thinking of PCI bus mastering, where the PCI slave temporarily takes control of the bus to read and write main system memory. This still exists in PCIe and thunderbolt, which is why bus mastering can be a security risk. CF poses no such risk. PCMCIA I don't think does either, since it is effectively a stripped down ISA. Later PC laptop cards look very similar but are actually CardBus, which is basically PCI. CardBus does support bus mastering. And the later Express card did too, in its PCIe forms
