Hello Robert, Is the R444 a reference to the resistor number or is this actually a surface mount with a resistance of 444 ohms? I'm not sure I have the dexterity or vision to solder that small of a component back on and I'm not that old.
It sounds like my best bet would be to wait for 2017.11 to be released (I assume this translates to Nov-2017 release?) and dd the image to the SATA drive and try again. You may have mentioned this already but will the current Debian X15 image work on the board if I dd it to an SD card and try to boot. My current configuration is set to SATA then SD so I am hoping it will just default to the SD for boot once the SATA fails Thanks again On Monday, October 2, 2017 at 9:44:31 AM UTC-5, RobertCNelson wrote: > > On Sun, Oct 1, 2017 at 5:22 PM, <mab.mo...@gmail.com <javascript:>> > wrote: > > Hello Robert, > > > > Thank you for the reply.
