Carsten Siegner has developed an hardware hack which connected to Pegasos Floppy Port it allows to switch off ATX power supply directly from MorphOS.

This hack requires modified version of Trackdisk device and a program called Motor_Tool into MOSSYS:C that should be renamed "Shutdown".

Here lays Motortool.lha

Carsten Siegner declines any responsibility for any damage which could occur to Pegasos Hardware using his hardware hack.

does it work for both pegasos1 and 2???

thanks and bye, MarK.

ps: this reminds me good old times of amiga and its hacks

That's hilarious!

I mean: the Pegasos hardware allows the machine to be shutdown by software. It already works with Linux... MOS1.5 is supposed to allow it as well: and people now hack the machine just to do what's it's already able to do :)

What next ? :)

Bounty for shutdown-feature?

1. It does not require a modified trackdisk.device.

2. Next is altivec support by connecting external hardware to the mic input.

it does.

yeah this is quite ridiculous.

Muahahahaha...
I just really have no time... Some really little thing prevents my shutdown command from working. Without any hardware hacks...

Although good intentioned, this is NOT the thing to spread to the user base. It is VERY Dangerous and VERY Hacky (in a bad way) People could effectively kill their boards, and these boards are exotic. Morphos "1.5" has shutdown built into kernel, and a shutdown for 1.4.5 could be done realitvly easily. Maybe the guys who can do it will do so after they see desperate threads like this...

I think, the hardwarehackis great.
It is a solution for now... Maybe, 1.5 will bring this feature some day, but today, there's no solution, that works.
( I'm tired of hearing all the features of 1.5 or the 1.3 firmware.. I have no chance to get it rigth now.)

And if there is a solution available, you can still use the hardware for different actions ..

Well, at least you can now do something useful with the floppy port

(floppies themselves haven't been useful in about a decade... Except for "retro stuff", which won't work with "normal" floppy interface anyway)

Totally right. But as some hardware hacks, a software solution can come later. When using some PCMCIA cards on A1200, you had to do a hardware-hacked pcmcia reset to get them working, and later came the software that allowed to do that reset... I'm personally not good with soldering and all that, and would not do that HW hack, but I think its a good idea anyway for skilled people who want this feature. Anyway, it was so a so simple solution, that I would never have thought abouy it :P. Nice work.

On a second thought, this does prove, that you CAN do something useful with the obsolete floppy connector / controller.

Of course, this hack isn't THAT useful, but it kind of proves, that it could be used for something else aswell

How about a hardware watchdog*, for example? Of course just about ANY hack could also be combined with this one aswell.

*
In case you don't know what a watchdog is, it receives a signal from hardware (sent by software) on certain intervals. If it won't get the signal, it assumes that the software has "locked" and resets the device.
Actually I guess something like this should be relatively easy to do in software outside abox aswell? Easy for "The Higher Beings", not us mere mortals, of course...

To be honest with you and with all I must say that I don't care at all.

I just reported the news, as an ambassador.

Hardware hack news it is enough important to deserve to be read.

To make modifications to hardware it is a matter of people wishes and wills.

I second that, either you know what you're doing then go on, or you don't and then you won't.

I like that hack and think about using it. kind of cool idea IMO.

Quote:

Did anyone test to see what happens when you actually have a floppydrive connected though (fireworks, shredded disks, exploding batteries, anything)? ;)

..anyway, as mentioned earlier this method of shutdown is unsafe and can lead to loss of data (same as with powerbutton, but without the 3 second delay to change your mind)...

then you probably shut down the whole house.

and when a floppy is inserted you can get troubles for having mass destruction weapons at home.

if it were only 3s, I guess my maschine takes 5s and about felt 5 mins...

Anyway, changing mind is for girls but not for 'Teh real man'
