hi there, i am just reading up on things, and here is a very nice explanation how and why some of the bioses chose their geometry.
http://www.pcguide.com/ref/hdd/bios/modesECHS-c.html quite some russian rulette, innit :] it also kind of explains why when a certain disk capacity is surpassed, only the n/255/63 logical c/h/s geometry makes sense---the numbers are just getting bigger and bigger... i wonder what will happen when 65536/255/63 is reached, what kind of frankenstein translation table will come into life just to save c/h/s again. maybe there will come an LBA only age, i mean fdisk-wise, not disk-wise, those are already LBA only... pc technology is the ugliest no matter where one looks (640K, ATA disks, pciide, ACPI, the list goes on and on) complete lack of visionary thinking. and in the other side of the ring, complete overengineering (ipv6, EFI, ASN.1, etc) -f -- self-reference (n.): see self-reference
