BIOS Configuration
EPC-100 Hardware Reference 3-7
Transfer Mode
This option selects the mode that the System BIOS uses to access the hard disk. The
selections are:
Standard (default)
Fast PIO 1
Fast PIO 2
Fast PIO 3
Fast PIO 4
Fast DMA A
Fast DMA B
Fast DMA F
Older hard disks only support “Standard”. Newer hard disks adhering to “Fast ATA”
or “Enhanced IDE” specifications may support the fast programmed I/O or DMA
modes. Note that autotyping may change this value depending on the transfer modes
that the hard disk reports it supports. The fast DMA modes take full advantage of the
onboard bus mastering hard disk controller and should yield the highest performance
when used in conjunction with multitasking operating systems that support it. The
default is “Standard”.
