Hi Bodhi! I try to install latest debian (12, kernel 6.10) on my ds411slim. The best solution would be to put u-boot+cfg + kernel+initRD on the FLASH and the rest on the USB/SATA. I've already done it successfully on couple of qnap boxes. Now; the stock NOR SPI M25P32 on ds411slim is 4MB only, it is too small to store so much data. So I soldered a new M25P128, 16MB NOR SPI instead.by teodolit - uBoot
