Options: Primary / Secondary 52 http://www. tyan. com 3. 4. 5. 1 Primary Master/Slave Sub-Menu The system displays advanced details like the number of heads/cylinders/sectors on the detected disk and the maximum storage capacity of the disk. This option lets you set the following hard disk parameters: Type Selects the type of device connected to the system. Options: Auto / CD/DVD / Not Installed / ARMD Multi-Sector Transfers This option allows you to specify the number of sectors per block for multiple sector transfers. Options: Disabled / 2 Sectors / 4 Sectors / 8 Sectors / 16 Sectors LBA Mode Control Enables or disables LBA Mode. In LBA Mode, instead of referring to a cylinder, head and sector number, each sector is instead assigned a unique "sector number". In essence, the sectors are numbered 0, 1, 2, etc. up to (N-1), where N is the number of sectors on the disk. In order for LBA to work, it must be supported by the BIOS and operating system, but since it is also a new way of talking to the hard disk, the disk must support it as well. All newer hard disks do in fact support LBA, and when auto detected by a BIOS supporting LBA, will be set up to use that mode. When LBA is turned on, the BIOS will enable geometry translation. This translation may be done in the same way that it is done in Extended CHS or large mode, or it may be done using a different algorithm called LBA-assist translation. The translated geometry is still what is presented to the operating system for use in Int 13h calls. The difference between LBA and ECHS is that when using ECHS the BIOS translates the parameters used by these calls from the translated geometry to 53 http://www. tyan. com the drive's logical geometry. With LBA, it translates from the translated geometry directly into a logical block (sector) number. LBA has in recent years become the dominant form of hard disk addressing. Since the 8. 4 GB limit of the Int13h interface was reached, it became impossible to express the geometry of large hard disks using cylinder, head and sector numbers, translated or not, while remaining below the Int13h limits of 1, 024 cylinders, 256 heads and 63 sectors. Therefore, modern drives are no longer specified in terms of classical geometry, but rather in terms of their total number of user data sectors and addressed using LBA. Options: Disabled / Enabled 32 Bit I/O Enables or disables 32 bit data transfer mode. Enabling this option causes the PCI hard disk interface controller to bundle together two 16-bit chunks of data from the drive into a 32-bit group, which is then transmitted to the processor or memory. This results in a small performance increase. Options: Enabled / Disabled Transfer Mode These modes determine the speed at which data is transferred to and from the drive.
