I am using kernel 2.4.2 ac-18 and yep ofcourse I am not removing my cdrom power supply...... I tried hdparm -T and got ide_dmaproc: chipset supported ide_dma_timeout func only: 14 I have ASUS 440BX/F mb with intel PIIX4 chipset...... any suggestion Regardz daCodez > > Balazs.... > > OH the fun....what do you think you are doing? > Since you have not issued a power down command nor deregisterd the device, > because I have not publish hotswap-ata yet....thus you can not do this in > a pretty way..... grumbles for Bryce..... > You are lucky that you have to burned the mainboard. > The open-collector pull on the channel will destroy the buffers on the > device.
