I have been using tf536r2_2020_08_06_alpha.zip for a while on a Mega 4 ST with no problems in Emutos. TOS 2.06 works with maprom but no autoboot off C:. The ASCI port is non functional on both OS's. Could you test your Satan drive?
Ultrasatan works fine here with that firmware on an 520ST.
Copied some files across on both the PC and ST, and started Frontier from a FAT16 card that was partitioned on Windows.
This was on EmuTOS.
Ultrasatan and the card is detected by HDDRIVER on TOS2.06 but it won't read the card.
I'm guessing I probably need to make one of those TOS/WIN hybrid partitions using HDDRIVER for it to work on Atari TOS?
Regarding booting from IDE, the FAQ for HDDRIVER has this to say about it:
Are there any limitations when booting from IDE?
TOS can only boot from a drive connected as master drive to the first IDE port if the drive was partitioned while being connected to the Atari's IDE port. This is caused by the wiring of the Atari's IDE port not having the same byte order used by other platforms for IDE.
The IDE interface on the TF53x has standard wiring, so it's different from an Atari IDE port.
Atari TOS boots fine off the IDE for me with an adapter, or twisted cable, to make the interface same as on the Atari.
(And with the IRQ tethering to ACSI10 to make Atari TOS happy..)
My CF-Card which was originally partitioned on an Atari IDE interface before I got a TF53x boots fine on both EmuTOS and Atari TOS.
