IDE DMA transfer access
Setting to [Enabled] will open DMA bus master and execute DMA action in DOS,
which will make the data transferring faster. Settings: [Enabled], [Disabled].

The integrated peripheral controller contains an IDE interface with support for two
IDE channels. Choose [Enabled] to activate each channel separately. Settings:
[Enabled], [Disabled].
IO Devices Configuration
Press <Enter> and the following sub-menu appears:
Onboard FDC Controller
Select [Enabled] if your system has a floppy disk controller (FDD) installed on the
system board and you wish to use it. If you install add-on FDC or the system has no
floppy drive, select [Disabled] in this field. Settings: [Enabled], [Disabled].
COM Port 1/2
These items specify the base I/O port addresses of the onboard Serial Port 1 (COM
A) / Serial Port 2 (COM B). Selecting [Auto] allows AMIBIOS to automatically deter-
mine the correct base I/O port address. Settings: [Disabled], [3F8/IRQ4], [2F8/IRQ3],
[3E8/IRQ4], [2E8/IRQ3] and [Auto].
Parallel Port
This field specifies the base I/O port address of the onboard parallel port. Settings:
[Disabled], [378/IRQ7], [278/IRQ5], [3BC/IRQ7].
Parallel Port Mode
This item selects the operation mode for the onboard parallel port. Settings: [SPP],
[EPP], [ECP], [ECP+EPP] and [Normal].
EPP Mode Select
The onboard parallel port is EPP Spec. compliant, so after the user chooses the
onboard parallel port with the EPP function, the following message will be dis-
played on the screen: "EPP Mode Select." At this time either [EPP 1.7] spec or [EPP
1.9] spec can be chosen.
ECP Mode Use DMA
The ECP mode has to use the DMA channel, so choose the onboard parallel port
with the ECP feature. After selecting it, the following message will appear: "ECP
Mode Use DMA." At this time, the user can choose between DMA channel [3] or [1].
