[. . . ] Options: Disabled / Primary / Secondary / Both 3. 4. 3. 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: None / ATAPI Removable / CD-ROM / IDE Removable / Other ATAPI / User / Auto 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 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. 54 http://www. tyan. com 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 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. Options: Disabled / Enabled Transfer Mode These modes determine the speed at which data is transferred to and from the drive. Options: Standard / Fast PIO 1 / Fast PIO 2 / Fast PIO 3 / Fast PIO 4 / FPIO 3/ DMA 1 / FPIO 4/ DMA 2 Ultra DMA Mode Enables or disables Ultra DMA Mode. Ultra DMA (UDMA, or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer's data paths (or bus) to the computer's random access memory (RAM). The Ultra DMA/33 protocol transfers data in burst mode at a rate of 33. 3 MBps (megabytes per second), twice as fast as the previous Direct Memory Access (DMA) interface. Ultra DMA support in your computer means that it will boot (start) and open new applications more quickly. It will also help users of graphics-intensive and other applications that require large amounts of access to data on the hard drive. [. . . ] This shifts the processor over and down, guiding it into the board and locking it into place. 80 http://www. tyan. com Technical Support If a problem arises with your system, you should turn to your dealer for help first. Your system has most likely been configured by them, and they should have the best idea of what hardware and software your system contains. Furthermore, if you purchased your system from a dealer near you, you can bring your system to them to have it serviced instead of attempting to do so yourself (which can have expensive consequences). If these options are not available for you then Tyan Computer Corporation can help. [. . . ]
