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.
