Introduction
The PCM-4898 is an enhanced, all-in-one single board 486 compuer
with an on-board Ethernet interface, local-bus SVGA controller. The
PCM-4898 offers all the functions of an AT-compatible industrial
computer on a single board, but it fits in the space of a 5¼" floppy
drive (only 5.75" x 8"). For maximum performance, the PCM-4898
also supports 2nd level cache sizes from 128 KB to 512 KB (32 KB x
8, 64 KB x 8, or 128 KB x 8).
On-board features include four serial ports (RS-232 and RS-232/
422/485), one parallel port, an enhanced IDE hard-drive controller
(for up to two drives), a floppy-drive controller and a keyboard/PS/
2 mouse interface. The PCM-4898 is also fitted with a composite
video output connector allowing for easy access to your television.
The board's watchdog timer can automatically reset the system or
generate an interrupt if it stops due to a program bug or EMI
problem.
The PCM-4898 also complies with the "Green Function" standard
and supports three types of power saving features: Doze mode,
Standby mode, and Suspend mode.
All display and Ethernet configuration is done through software. A
single Flash chip holds the system BIOS, VGA BIOS and the
network boot ROM function. This minimizes the number of chips
and eases configuration. You can change the display BIOS or
install a boot ROM simply by programming the Flash chip.
