Figure 80. Read Native Max Address (F8h)

This command returns the native max LBA/CYL of H D D which is not effected by Set Max ADDRESS
command. Even if the Address Offset mode is enabled, the native max LBA/CYL oh H D D is returned.

Output Parameters To The Device

LBA mode.Indicates the addressing m o d e . L = 0 specifies CHS mode and L = 1 does
LBA addressing mode.

The device number bit.

Indicates that the device number bit of the Device/Head

D = 0 selects the master device and D = 1 selects the

slave device.

Indicates that the bit is not used.

Input Parameters From The Device

Sector Number

In LBA mode, this register contains native max LBA bits 0 - 7. ( L = 1 )

In CHS mode, this register contains native max sector number. ( L = 0 )

Cylinder High/Low

In LBA mode, this register contains native max LBA bits 8 - 15 (Low),

16 - 23 (High). ( L = 1 )

In CHS mode, this register contains native max cylinder number. ( L = 0 )

In LBA mode, this register contains native max LBA bits 24 - 27. ( L = 1 )

In CHS mode, this register contains native max head number.(L=0)
