lnstallation/Support Tips

Power

The Equity le has a power supply that is switchable between

115 V, for USA and Canadian use, and 230 V, for use in

other countries. There is no manual switch, as the power

supply is auto-sensing.

Video Adapters

m-w

When using monitors other than the Epson VGA

monitors with the Equity le, it is recommended that

you power the monitor on before the computer.

This ensures that the Equity le will automatically

sense the monitor type at boot.

--- lt is possible to use other optional video adapters in

the Equity le. However, CGA is not an allowed

option due to a register group conflict.

Installing Floppy Disk Drives

m-w

When installing a floppy disk drive as drive B,

remember to set the drive select jumper to the

second position and attach the pass-through

connector on the floppy drive controller cable to the

drive, not the end connector.

Installing Hard Disk Drives

--- lf you are having difficulty in formatting the hard

disk drive, try starting over with the Unconditional

Format option in diagnostics.

--- When running a low-level format on the Equity le

optional hard disk drive, set the interleave to 5 for

optimum performance.
