Version 1.5 of Atari ST ATX
All small mistkes fixed, everything works fine. There are two jumpers, now You can chose which TOS (1.04 / 2.06) You want to use.
IDE works good, ACSI also works good.

For STGA1040 I'm using STGA_ET4000T3_V301.zip driver from https://silicon-heaven.org/atari/nova/ST - MegaST/STGA/
Local mirror:
STGA_ET4000T0_V301.zip for DAC TR9C1710 8-bit
STGA_ET4000T3_V301.zip for DAC KDA0476 8-bit
STGA_ET4000T6_V301.zip for DAC SC11486CN-66 15-bit
STGA_ET4000T8_V301.zip for DAC W82C490 24-bit (?)

I was informed, that order of driver files in AUTO folder on CF card is very important. You have to put them one after another: first one is Emulator.prg then Menu.prg/Xmenu.prg and then Sta_vdi.prg and then rest of them.

My ET4000 model is:
