New BIOS Expander Lets PC Users Step Up to High-Capacity Disk
Drives

ORLANDO, Florida -- Distributed Processing Technology, the leader
in the field of caching disk controllers, has unveiled a new
read-only memory (ROM) chip that expands the BIOS drive table of
286- and 386-based PCs. The BIOS Table Expander (BTE) chip adds
support for nearly 500 disk drives, including the new high-capacity
ESDI drives. It is designed to be installed on the company's
SmartCache(TM) disk controllers.

Many PC operating systems such as DOS, PC-MOS, and PICK rely on the
computers BIOS drive table to define the type and size of disk
drive that can be used. Many of the newer high-capacity drives are
not listed in the BIOS drive table, limiting the system
integrator's options. The BIOS Table Expander chip solves this
problem by adding support for most of the drives on the market. 

DPT president Stephen Goldman says the increasing number of users
on a single PC prompted the development of the BTE chip. "Our
SmartCache disk controller removed the disk performance bottleneck
in PC multiuser systems and allowed people to add more users. Now
those new users need more disk space. Prior to the BIOS Expander,
these systems were limited to smaller capacity drives. With the
BTE, even drives with 700MB or more can be used with any operating
system."

The BTE chip is available now for all models of the SmartCache
controllers. The suggested list price is $50, in the U.S.

A privately held company founded in 1977, DPT designs and
manufactures caching disk controllers for a varity of mini- and
microcomputer systems. The company is based in Orlando, Florida
with offices in San Francisco and Los Angeles.
