Downloadable highspeed SIO
Verfasst: 20.03.2022 09:23
Hi,
not every software runs with a patched OS containing a highspeed SIO, that's why all my Ataris run the XL/XE OS.
Unfortunately loading everything without highspeed is a pain in the a***.
I do know that the FujiNet can transfer in highspeed, but it only does so if there is something on the Atari supporting highspeed.
SpartaDOS for example has got built-in highspeed code, so there is no problem with that. But there is software that hasn't got built-in highspeed but tries ot obain such code from the drive and use this instead of the OS SIO.
This feature was invented with the Speedy 1050 (and BiboDOS), but is supported by APE (only more recent versions) as well.
One software that uses this feature is Micro-SpartaDOS, a gamedos written by Jiri Bernasek that uses SpartaDOS file system and disks up to 16 MB.
The downloadable highspeed feature works like follows:
- host sends command $68 to the drive and waits for a two-byte reply, those being the length of the SIO-code the drive would send
- host sends command $69 to the drive, DAUX1 and DAUX2 containing the address, the SIO code should be relocated to and then receives the readily relocated SIO code
Would it make sense if the FujiNet module supported this, too?
