Me again So I'm here with sparta 4.47, bios 0.35, pbi bios 1.3
Some oddities I've found (I don't consider it is a bug, just different behaviour to original bios):
1. if you run old school vbxe demo from sparta with X /C OLDVBXE.XEX and then go to ulitmate bios with [help] + [reset] the color theme is shifted. I use by default 01, which is, to my eye - brown, after runing demo it's blue. All schemes are shifted untill you power cycle machine with back switch.
2. when in sparta or sc, if you try to change drive to some that does not exists AND type some command like DIR [return] or non existing binary name [return] the keyboard looses auto repeat. But in strange way. You can not use same key twice in a row, the second press does nothing. So I can type ie. COLD [return] because these are different keys, but I can not use [control+down/up arrow] more than once, to navigate. I need to press [control+down/up arrow] [delete or some other key that does nothing] to repeat It's even better! If I now type KEY ON, the whole keyboard stops responding Only [help] key is working.
3. when I go to ultimate bios and press L for loader and mount single ATR with [return] key it works as expected. But after [help] + [reset] and C (cold) the ATR is still mounted as D1: It's nice because I can now play with ATR content but I don't know how to unmount it :/ The onnly way seems to be power cycle machine with back switch.
That's all for now
