utri007 Posted April 29, 2020 Share Posted April 29, 2020 (edited) Friend of mine made those files to me and I burned them to eprom. When I trun Atari on I get this error screen: I really would like to get my Lightning board in use. What is problem / what I have made wrong? I have set of these M27C256B https://www.aliexpress.com/item/4000110450926.html?spm=a2g0s.9042311.0.0.27424c4dlfNGNq Edited April 29, 2020 by utri007 Quote Link to comment Share on other sites More sharing options...
guus.assmann Posted April 29, 2020 Share Posted April 29, 2020 What's the speed of the Eproms? 120nS would be ok. Slower may cause problems. BR/ Guus Quote Link to comment Share on other sites More sharing options...
utri007 Posted April 29, 2020 Author Share Posted April 29, 2020 Speed shouldn't be a problem Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted April 30, 2020 Share Posted April 30, 2020 That's bad EPROM content, most likely. Is that Lightning board work well when loading driver from floppy ? Quote Link to comment Share on other sites More sharing options...
utri007 Posted April 30, 2020 Author Share Posted April 30, 2020 Lightning board is not connected at all. This is just test after TOS change. I haven't patched TOS files myself. Never used ST, wouldn't know what to do or how. Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted April 30, 2020 Share Posted April 30, 2020 If it works well with ROMs (EPROMs) which were in machine it is clearly problem with this, 'IDE enabled' EPROMs . And not relevant what is concrete problem. Btw. it is not about IDE 'enabling' . Only TOS 2.06 and later have IDE autoboot support. TOS 1.xx needs extra code for that. Myself did it some 12 years ago. http://atari.8bitchip.info/astams.php At bottom of page. There is even ASM source of code for it. + instructions, object code for patch.

utri007 Posted April 30, 2020 Author Share Posted April 30, 2020 (edited) But it is IDE enabled as it is patched with this https://github.com/czietz/ideboot/ It is clear that problem is eproms or patched images. Maybe i wold just try to burn normal tos to them and see if they work at all. Edited April 30, 2020 by utri007 Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted April 30, 2020 Share Posted April 30, 2020 Word 'enabling' suggests that there is code for it in TOS 1.xx, but is disabled from some reason. While IDE with Atari ST(E) was not used before 1991. Quote Link to comment Share on other sites More sharing options...
utri007 Posted May 1, 2020 Author Share Posted May 1, 2020 Now I have a working TOS with IDE support. Thanks for involved. I have tested it with CPU relocator and CPU it works. Now I have a problem with Lightning's jumper settings, I ques. It doesnt boot, but seems that jumpers are for a Cloudy TOS board. There is no guide for "how to set up Lightning with onboard TOS". http://wiki.newtosworld.de/index.php?title=Cloudy Quote Link to comment Share on other sites More sharing options...
