Just curious, read that NT4 doesn't support IDE HDD Block Mode and data can be corrupt if this feature is enabled in bios. So wonder about OS2 how well is this feature supported by the native system/drivers in OS2? Up to 64KB of data can be transferred per interrupt with IDE HDD Block Mode enabled. If you disable IDE HDD Block Mode, only 512 bytes of data can transferred per interrupt.Info about above problem within NT4 can be found here.
