i was not able to get the drives to be recognized when sata mode was set to RST in the bios. it would be nice that one didn't have to switch RST - AHCI in bios to get the stock windows installation to boot back and forth.

the touchpad is a i2c_designware_platform device. the following modules are necessary: intel_lpss_pci, i2c_designware, pinctrl_sunrisepoint, i2c_hid. To configure the touchpad as an actual touchpad with two-finger scrolling etc, then it is also necessary to enable the HID_MULTITOUCH option in the kernel. Without this, the touchpad may only be recognized as a pointer/mouse. More information at this forum post.
