How to _inp(), _outp() on 0x1F6, 0x1F7and 0x1F0 under Win95/98

Hi Everybody

Can anyone help me with accessing I/O port 0x1F7, 0x1F0 under Win95/98.
How can it be implemented ??
DeviceIoControl()
Thunking 16bit App
VXD
Volume Locking (Interrupt 21h Function 440Dh Minor Code 4Ah Lock Logical Volume
Interrupt 21h Function 440Dh Minor Code 4Bh Lock Physical Volume)

Thanks,


_outp(0x1F6, 0xA0);
_outp(0x1F7, 0xEC);

for(i = 0; i < 256; i++)
{
hdInfo[i] = _inpw(0x1F0);
}

dude..
you have to communicate with the IDE/ESDI device driver to get the ATAPI Identify String. You can't just acccess protected ports. Ain't Protected Mode grand?

I just responded to your previous post of this same message: you have to communicate through the IDE/ESDI device driver to get ATAPI device identify data. The ports are protected by the driver and are ONLY accessible by IT.
