Type
In most cases, the IDE interface involves a hard disk drive
but the interface can involve other devices. If you are not
using an IDE hard disk drive, select ‘None.’ Also select
‘None’ if you use an SRAM PC card. If you use a disk
drive device not conforming to ANSI standards and cannot
employ the Autotype feature, select ‘User’ for the type and
enter the correct values for disk cylinders, heads, etc. from
the drive’s documentation or label.
There are some restrictions when setting up devices on the
EPC-30. Booting from an ATA card can only be
accomplished using a ROM extension such as the
PhoenixPICO PCMBOOT.BIN file. The ROM extension
reads the Card Information Structure (CIS) from the
PCMCIA card and reads the geometry of the card.
Once you complete the setup for the IDE Master, you can
choose the IDE Adapter 0 Slave Sub-menu to set up a
second hard disk drive. When the setup is complete, press
the ESC key to return to the Main Menu.
Multi-Sector Transfers
This option allows the user to configure the System BIOS
to read ahead by the specified number of sectors whenever
a disk access is performed. This has the effect of reading
more data at once to reduce the absolute number of
discrete disk reads performed by the operating system,
which may increase system performance. The possible
selections are disabled, 2, 4, 8, or 16 sectors. Note that
autotyping may change this value if the hard disk reports
that it supports block accesses. The default is disabled.
LBA Mode Control
When enabled, this option allows the System BIOS to
reference hard disk data as logical blocks instead of using
the traditional Cylinders/Heads/Sectors (CHS) method.
This option can only be used if both the hard disk being
configured and the operating system support Logical Block
Addressing (LBA). If disabled, then CHS mode is used.
