Does anybody think, this (still fictional) hardware-mod is worth a try ? (also see attached pic) I`d like to use my Jukebox as a backup device for compact flash cards (digicam). Since CF cards are true IDE/ATA devices, perhaps this works. I already have some experience with passive CF2IDE adapters. (booting Linux from that) I`m also not shure, if could "see" 2nd. device from within rockbox without too much effort. If there is a chance, that a master/save combination can be handled with existing archos hardware, perhaps I will disassmble my JB and look onto PCD how HDD is being interfaced. Yes - we need to add code there - but maybe this is not too difficult. CF usually are formatted witch fat12 or fat16 - can existing fat32 driver code handle that, or do I need addidtional driver code? I read the isd300 manuals and I`m quite optimistic, at least ISD300 can handle 2 devices -----snipp--- Master/Slave Selection Bit (5) Device number selection. This bit is valid only when "Skip ATA/ATAPI Device Initialization" is active. Under ISD-300A control ("Skip ATA/ATAPI Device Initialization = '0'), the value is ignored. 0 Drive 0 (master) 1 Drive 1 (slave) ---snipp---- But as i see - ISD300 is ONLY needed when interacing to usb!? So we don`t really need support for 2nd device of ISD300 - since what we get would be just "another" USB CF Card reader - and they are cheap today - anyway ;) Please tell me, what you think regarding chances for success on that. regards Roland PS: Shure , that "hack" won`t fit into the original JB case - but I will build a new case around my JB soon, anyway.
