Cybppc scsi / makecd

[elendil]

Hi. I have no idea if this is soft- or hardware related, actually, but here goes:

I own a cyberstormPPC and a couple of old scsi2 burners (got a converter with the board). One is unupported in DAO by makecd (according to their manual), so finally I managed to aquire the yamaha cdr100 which they claim should work very nicely with DAO and whatnot. Problem is it does not. It crashes as soon as I press 'start', no matter if it is in test mode or not, with some "write failed blahblah code 800004" or something.

It burns TAO just fine, so I would blame the burner / makecd normally, but then I realized that makecd also crashes during finalisation (always) of vcd burns and that the new burner rejects any audio cd.

Is it possible to have it work as well as it does (I have an UW hd and used to have two old burners on) for a couple of years, if it is wrongly terminated?

Could there be some option I need to change for the device?

What is the latest cybppc flash? I forgot the thread but someone claimed to get a version above some number I also forgot, but checking mine I think it was lower, yet the one on dce-com.de is even lower.

I suspect it is the controller as it sometimes (although) rarely reports an 'scsi error' thingie in which it kindly informs me that I can throw some debugging to the serial port, if I like. I forgot what it said exactly but it became less frequent as I flashed the board from time to time, back when P5 existed.

Hope someone can help me out here - and I apologize in advance for the poor formatting and wording. It is four am here and I should have been to bed long ago

Sincerely,

Funny as it sounds try putting a heat sink on the SCSI chip. I got a massive increase in speed simply by mounting a heatsink on the symbios chip. Fixed my lock ups too. According to SYSSpeed I now get 9.8 megs a second transfers off my IBM SCSI 2 hardrives. before all I got was 2.5 megs a second.

I wonder how many Amiga users live with lack luster speed because Phase V decided to save a few Cents. Not to mention premature failures from blown mach chips becuase they over heated and died. I got heatsinks on two Mach chips that get so hot the heatsinks will burn your hand.  

BTW I use MakeCD here and it works fine.
try downloading the newest updates off the web site. http://makecd.core.de/

also you can download the newest flashroms from DCE.

Hope that helps

Hm, upgrading to 3.2beta 10 made it stop crashing when typing start, but now I have run out of CD's to see if it actually works

I would still like a pointer to the latest flashrom for cyberstormPPC.

If I mount and load a CD after I burn one with the cybppc.device, I get that dreaded scsi error requester and usually reboot right away. Seems to be a bug in the scsi device someplace. I'm not complaining too loudly about it, because otherwise it works very well. SCSIBench, SCSISpeed and SysSpeed all report my drives' transfers top out at just under 30 megs a second. It's kinda fun watching the DOpus progress bar on 5 meg files whip across like it's copying icons. :-D

Edit: Forgot to add, what's the best way to attach a heat sink to a chip mounted sideways?
