While preparing wrapping ATA(4) low-level drivers code into CAM SIM, I would like to remove CHS addressing support to make code cleaner. CHS addressing is officially declared obsoleted and replaced by LBA. Since ATA/ATAPI-6 specification (October 2001) it is even no longer documented. Have anybody seen ATA drive without LBA support in last years? Any other objections against removing it? -- Alexander Motin
