A german guy (developing floppy-controllers) asked me, if its possible to access hardware registers with PureBasic under the three different PB versions. As there isn't a command included, does someone know a solution/example under Windows, Linux, Amiga ? Thanks in advance

Regards
AndrÃ©

Hi Andre,

Can't imagine he is developing a floppy controller that fit's Amiga and PC

Check this to do it under windows NT-2K-XP, he needs to write a dedicated devicedriver or use WinIO or similar driver.

Linux and AmigaOS are ok (nothing is protected on AmigaOS BTW)

fred: how can you access a hardware port directly in
a secure _protected mode_ operating system like Linux?
In a secure OS this is never allowed because it could
crash the hardware.
For example: When 3 apps access a port at the same time,
things can mix up in a very bad way.
Thats the reason you have to use device drivers for
everything. The device driver manages the access requests
from different apps, so nothing gets mixed up.

So you say that Linux is competely unsecured in this way ??
Really ??

I never said it's unsecured, there is some API which let you access the hardware registers of all devices, that's all.

True, i used linux hardware monitor PDF's to get information i use in RAIDmonitor on windows.
The functions to access PCI Config Space etc.. are build in.

Sorry Fred, got that wrong.

Andre asked for help and you just answered
"Linux and AmigaOS are ok", so i thought
only little ASM OUT and no extra stuff
is needed here (couldnt believe that).

Why not tell us how to access it on Linux and Amiga?

On Amiga, you can poke it directly (I've already done it with custom chips... who called Paula ?

). On linux, you have to have root access, and then open the device (/dev/xxxx) with standard file command. ioctrl() can be used to perform special op, which are of course filtered and computed by the device driver.

Mmm... I guess he is developing a driver for the Catweasel controller, right? Well.. to access hardware registers in Win9x... you need to develop a .vxd (since it works in ring-0 mode with no protection). In WinNT/2000/XP, I think there are devices to access physical resources.
