Note that STiNG does not support DHCP and thus requires a hard-coded IP address. Further be aware that the DaynaPort driver for STiNG does not support LUNs > 0. This in particular affects the internal host adapter of the MegaSTE, which only supports a single SCSI ID. On the one hand TOS can only boot from LUN 0, on the other hand the DaynaPort driver also requires the DaynaPort to be emulated for LUN 0. So with the MegaSTE's internal adapter you can either have a drive TOS can boot from, or a DaynaPort emulation, but not both.
It should not be a big deal to extend the DaynaPort driver with LUN support. On GitHub there is suitable [code for the SCSI Driver](https://github.com/uweseimet/atari_public/tree/main/PISCSI), which automatically detects a particular device independent of its SCSI ID or LUN.

Also be aware that the DaynaPort drivers for STiNG and MiNT do not support LUNs > 0. This in particular affects the internal host adapter of the MegaSTE, which only supports a single SCSI ID. On the one hand TOS can only boot from LUN 0, on the other hand the DaynaPort drivers require the DaynaPort to be LUN 0. You either attach the one or the other device. The authors of the respective drivers, who are still active in the Atari developer community, are aware of this problem. It is not clear, though, whether they will address it.

As long as there are no DaynaPort drivers supporting LUNs > 0, as a work around there is a <a href="https://www.hddriver.net/forum/viewtopic.php?t=317">program for the AUTO folder</a>, which maps ACSI IDs to LUNs on the Atari.
# Troubleshooting and limitations
- On the Mac, if the DaynaPort installer complains about a Network file in control panels you will need to use [ResEdit ](https://macintoshgarden.org/apps/resedit)to make that file visible, then move it out of the Control Panels folder and try the install again.
