1050 Posted January 14, 2018 Share Posted January 14, 2018 I've tried every mode and had troubles setting the mode too. Literally at my wits end and she won't boot the 360K XF-551 disk with DOS.SYS on the backside. May have been a flaky eprom doing most of my troubles. But thanks for the run down on how to do it again and I will try it again. But my takeaway is that I'm having a lot of trouble with this and it shouldn't be so much trouble. 1 Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted January 14, 2018 Share Posted January 14, 2018 I read on another thread that the double sided internal PBI drives in a 1450XLD would address side 2 as drive 2, and also write the data 'backwards' in a way that was compatible in a single sided drive when flipped. Great ingenuity there that never made it out there! Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted January 15, 2018 Share Posted January 15, 2018 One of the ideas for the 1450 drive was to buffer the whole track and write the data backwards from the buffer without switching rotation, since almost all copy protection was on disk intended to be drive1, this would make access faster on the extra drives and maintained compatibility across all the drives... copy protected disks worked fine on drive 1 and 3, and drives 2 and 4 could still read and write disk understood by all..... the buffer was key... without it...way too big of a performance hit.....

StefanD Posted January 17, 2018 Share Posted January 17, 2018 Hello, I'm the author of the Hyper XF ROM. There is only one version of Hyper XF (1.0) and there are no known bugs. Unfortunaly, I haven't ever written any special software for the Hyper XF and don't plan to do it. Following software is missing: - Fast sector copier: should analyze track 0 with command g and then use the found track layout to read the other tracks fast (by using the appropriate sector interleave)- Read/Copy ST/IBM 360K/720K disks: by using command t- Track analyzer: by using command g (and perhaps t)- Copy protected disks: with commands g, t and e Since everybody uses SIO2USB/SIO2SD/SDrive today, I would say, a Track analyzer would be the most interesting software - and it's not very difficult since command g does most of the needed work. If you want to write software for the Hyper XF, I would explain the commands in detail. Here is a short overview of the modified and new commands: S: Supports density check optionsW: Writes always without verify (like P does)?: Get Ultra Speed Pokey divisor (=9)Space: Format background. Returns immediately from the SIO call, before formatting starts (same as in Speedy ROM)f: Formats with predefined sector numbers (some other ROMs have this)c: Configure mode. Sets the operation mode (like the Hyper XF menu does). Default is X (same as standard XF551)e: Extended format. Formats one track with an arbitrary format (sector numbers, gaps, error sectors can be defined)g: Get track info: Analyzes one track. The result can be used by command e to duplicate a track layout exactlyt: Read error sector. Reads a Single/Medium error sector fast (without retry) or one half of a 512 byte sector.u: Update error sector. Writes an error sector in Single or Medium Density 6 1 Quote Link to comment Share on other sites More sharing options...

Hi @StefanD consultation then these tools were not created by you? Hyper XF.atr in the case that it does say what does the readme file say? since it is in German but some letters are lost. 😅 Quote Link to comment Share on other sites More sharing options...

Hyper XF.atr 90.02 kB · 4 downloads in the case that it does say what does the readme file say? since it is in German but some letters are lost. 😅 In the Readme Stefan Dorndorf (the author of Hyper-XF-OS) tells Abbuc Floppydoc Erhard Pütz what the files are for: *.COM/*.BAS: files to set the Hyper-XF mode (Hypmode.COM), to patch a few DOS versions for Hyper-XF highspeed SIO (HPATCH.BAS) and Hyper-XF highspeed SIO driver (HSIO.COM) for Bewe-DOS *.OBJ: Hyper-XF-OS version A and B as OBJ files (not ROM files!) H1A, H2A, H3A: german manual for Hyper-XF-OS Conclusion: These tools (COM, OBJ, etc. files) are indeed all from Stefan ! It was Stefan who did send this disk to Erhard, no clue if Erhard or someone else released the diskette to the public. But as he stated above a fast sector copier, track analyzer, track copier (for copy protected disks) and ST/PC diskette reader for the Hyper-XF are all missing. Since most Atarians use SIO2xyz nowadays, he has no plans to ever write these missing tools for the Hyper-XF. 1 Quote Link to comment Share on other sites More sharing options...
