I understand this. But as i see this, this special device has one pin that it put to ground enables write protection. So what i that was: why not put this adapter between it that does nothing but connecting all pins from the device to the motherboard directly, except one, #30, which can be set to ground or whatever using a switch. As #30 seems not to be used by normal ATA, it should make not difference to the motherboard. the adapter is just an physical extension to avoid brazing on the ATA device itself... > > Charles Steinkuehler > http://lrp.steinkuehler.net > http://c0wz.steinkuehler.net (lrp.c0wz.com mirror) > _______________________________________________ Leaf-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-devel
