although some modern PC BIOSes have problems with manually entering the heads/cylinders as you might find on the label of an IDE hard drive from 1992. additionally I have found that modern udma/133 parallel ata drive controllers have less than perfect compatibility with some very old IDE stuff. while a 'vintage' motherboard like something with an intel 440fx or 440bx chipset from the very late 1990s should work.
- dfox 5y agoAll IDE drives are linear block devices and the CHS numbers set in BIOS are only necessary to make the BIOS happy. The types and CHS numbers were relevant for MFM/RLL harddrives without integrated controller. The IDE interface is essentially an simplified ISA bus on a cable and all of what should be called controller resides on the harddrive, in fact that is what both IDE (Integrated Drive Electronics) and ATA (AT Attachment, as in "AT bus" = "16-bit ISA") acronyms alude to. If you only intend to access the drive from Linux (ie. clonezilla) you can simply ignore the BIOS settings as Linux kernel will detect the drive correctly even when it is not configured in BIOS at all.
