Cylinder-head-sector - Wikipedia
网页Cylinder-head-sector (CHS) is an early method for giving addresses to each physical block of data on a hard disk drive. It is a 3D-coordinate system made out of a vertical coordinate head, a horizontal (or radial) coordinate cylinder, and an angular coordinate sector.

Counting disk capacity using cylinder-head-sector model
网页In brief, CHS numbers do not have much value these days and are actually reverse-calculated from the actual capacity in bytes. That is, your disk capacity is actually 786432000 bytes. Let's calculate the number of cylinders for your case: bytes b/S H S C. 786432000 / 512 / 255 / 63 = 95.61157796451914.

hard drive - SSD head / cylinder / cluster details - Server Fault
网页Only problem is that it won't boot. It freezes on POST. In the BIOS (from the 1990s), we need to specify some values, called 'HEADS', 'SYL', 'CLUSTER', and 'LANDZ'. Unlike traditional HDDs, this drive obviously has no platters.
4.11 What is the CMOS/jumper setting for my hard drive?
网页cyl * heads * sec/tr * 512 which gives the capacity in bytes! Dividing by 1000000 or 1048576 gives the capacity in Megabytes or MB respectively. If you get problems when installing 2 HD's with correct BIOS and jumper settings, try to swap drive 1 and 2, often that helps. Please don't flame me because of the 'layout' of the list.
