IRMAtrac NT Help
DCA IRMAtrac Driver for Windows NT

The following is a list of options available for DCA IRMAtrac token-ring adapters.

Options

BURST  size

Chooses the burst size--2, 4, 6, 8, 10, 12, or DEFAULT. Change this option only if you receive an error while trying to read a diskette or tape in a floppy drive or tape drive. If an error is displayed, change the burst size to 10. If the error persists, reduce the burst size until the error stops. Default: DEFAULT.

Receive list

Chooses the number of receive buffers in the IRMAtrac driver's Receive Buffer Pool--2 to 32. Default: 16.

Xmit list

Chooses the number of internal queue entries for outstanding transmits--1 to 64. This option is required for the MAC to support more than one transmit simultaneously. Default: 64.

IRQ level

Chooses the interrupt level--2, 3, 4, 5, 6, 7, 10, or 11. Each adapter in your PC should have a unique interrupt level. Default: 3.
