CHAPTER

2PCM-4890 User's Manual
Introduction
The PCM-4890 is an enhanced, all-in-one single board 486 comput-
er with an on-board Ethernet interface, local-bus SVGA controller.
The PCM-4890 offers all the functions of an AT-compatible
industrial computer on a single board, but it fits in the space of a
5¼"floppydrive (only 5.75" x 8"). For maximum performance,the
PCM-4890 also supports 2nd level cache sizes from 128 KB to 512
KB(32 KBx8,64KBx8,or 128KBx 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 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-4890 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.
If you need any additional functions, you can add up to six
industry-standard PC/104 expansion modules, or use ISA
peripheral cards via the on-board ISA expansion slot.
