Zorro cards dissaperar on RBM Z2 bussboard

[Brian]

Hi everyone... found this problem today when starting to install Zorrocards to my A1200T system with a RBM Zorro2 bussboard.

First off I installed a GVP IO/Extender (yesterday actually)and it appeared to work fine though I didn't install it the system clearly saw it and I left it at that. Then (today that is) I installed my Ariadne Ethernetcard and the weirdest thing started to happen.

On a cold boot earlystartup menu show 3 Zorro2 boards (as I have a BPPC card showing there aswell). Reset and into the same menu again and one of the cards are gone. Let the machine boot and let OS3.9 reset the system and the second is also gone. Started SysInfo and SysSpeed and both only report my turboboard precent.

I simply can't imagine what is doing this, apart from my Zorro bussboard being fawked up or something, so any help/suggestions are received with open arms.

Offhand, I might guess that the system isn't getting enough power?  Or perhaps a loose connection somewhere?  Heat issue?  Lotsa stuff could cause it...

Heat is deffintily not the case... It's a towerhawk with extra fan on the back nad inside going over the turboboard and this happened right of the button when the system was still cold.

A loose connection shouldn't do this should it? I meen when I do a cold boot it's there again all of it and the same scenario starts all over again. Was so amazed I actually had to go through this 3 times to accept that it happened.

Power hmm... perhaps it's powerloss. The KeyOn module was useless to me since I didn't have a ATX PSU so I hade to make a custom one myself to take an AT PSU instead (200W). I hope it's just too long cables. I'll try remove the IO card and see if that helps cause the Ariadne is there to stay.

Hi!

I know this is a year old post,but I replied it anyway,as I browsed through some Towerhawk related
subjects.Anyway,

I think it has something to do with the relatively fast bootup time on the Amiga 1200. If you have
a fast spinning harddrive,A1200 starts the boot-up process immediately after the harddisk has spun up
thus it doesn't have time to register the other cards you have installed. If I recall correctly,this
is a very common problem that can be fixed by replacing your boot device with a slower harddisk.I also
have the same Towerhawk & OnBoard and I have X-Surf and an old Supra SCSI card. On a cold boot it recog-
nizes the X-Surf and after a warm boot,both cards are present.If I boot without startup-sequence,even
the X-Surf card may be lost.The placement of the cards is also crucial,try to fill them in order from
the first slot downwards (ie use the upmost first !).I read you have OS3.9 - how many times does your
computer reset on a boot-up ie. do you also use Blizkick,Loadmodule or similar ? My machine only does
one extra boot with OS3.9 installed as I've placed the ROM updates on my Blizkick commandline and
currently don't use the available Shell-update which requires the Loadmodule program.Maybe these extra
resets should be kept to a minimum (?).

Hope it helps in someway,there is some information available of the 'fast' boot-up time on A1200
on the net,but I don't recall where. I do recall that it's boot-up time is the fastest on classic
amigas,which in our case means that it doesn't wait long enough to find the cards.

Regards,
Kenneth
