Very nice, I like the 1.44HD disk as used on the falcon. This will provide a good access point to exchange files with.
Nice work @exxos ,@Icky

Re: FDC cookie
Doesn't TOS look for a specific bridged jumper on the STE in order to enable HD floppy support in TOS 2.06? I know it doesn't mean you can use HD floppies without the MOD, but maybe it requires a hardware jumper and not just the cookie setting in order to work?
Just my random thoughts.

Re: FDC cookie
@rubber_jonnie we have that jumper emulated in hardware, so it is set, only that register is never access for some reason..

Re: FDC cookie
@exxos Ah, ok I see. Could there be something that is specifically STE related which means it won't work?

Re: FDC cookie
So exxos got pi**ed off and did a binary hack in the OS...
Had a small side-effect
But for my first hack I think I did pretty well

Re: FDC cookie
- This has been eating away at you and me this last week. More you than me
At least its tracked down that its never going to work with the DIP switch settings on an STF as its also machine type specific i.e. STE

Re: FDC cookie
@Icky Yeah, the source is a mess! it seems to be literally checking for a STE machine.. I haven't yet quite followed exactly how it is doing that yet.. But I did not want to fake a STF machine as a STE anyway.. is more curiosity than anything... I will go snoop now actually...
EDIT:
Something to do with the video address register then Also looks like after that code it checks for DMA sound as well.
EDIT:
Code: Select all
#if (TOSVERSION < 0x300) | TP_50
move.b #90,(v_bas_l).w /* write low byte of video address */
tst.b (v_bas_m).w /* access the medium byte */
move.b (v_bas_l).w,d0 /* (which should reset the low byte on an STE!) */
cmp.b #90,d0 /* reset? */
bne.s nostedetect /* yes => STE detected */
clr.b (v_bas_l).w /* clear the low byte again */
tst.w (palette).w /* access the color palette */
tst.b (v_bas_l).w
nostedetect:
sne STEFlag /* <>0 => no STE hardware available */
#else
sf STEFlag
#endif
