Godzil (./19):
Does it work on all STe whatever the DMA chip on them?
There are users with Bad DMA using the device, as well writing at disk without corruption.
But, if you have a bad DMA equipped STE, you need 2 or 4 MB (better) RAM and use a hard disk image that loads EmuTOS entirely into RAM.
The problem with these computers comes from the fact that Atari ST/E computer constantly power on and off the TOS ROM chips,
that causes a lot of electromagnetic (EMC) noise.
When the TOS ROM chips are not used, due to you loaded entirely the TOS in RAM (this takes 256 KB of RAM),
this EMC noise is not present, and the disk is not corrupted at writing.
This procedure is discovered by user Stormy at Atari Forum,
As well, I provide EmuTOS disk image (its also readable in your PC computer) download link along with the tracking number message,
