- SUMMARY
- =======
-
- The Trantor 128 and 130B are 8 bit SCSI host adapter cards for the IBM
- PC/XT/AT and 80386/80486 computers. These host adapters have both internal
- and external connectors. The host adapters support I/O-mapped data transfer
- at any of one of four addresses (plus disable), zero-wait state operation
- for high-speed performance, and Boot ROM option.
-
- MORE INFORMATION
- ================
-
- The product included here is manufactured by Trantor Systems, Ltd., a
- vendor independent of Microsoft; we make no warranty, implied or otherwise,
- regarding this product's performance or reliability.
-
- Both the T128 and T130B have internal 50-pin and external 25-pin SCSI
- connectors. The internal SCSI connection is marked with a silk-screened "1"
- on the board adjacent to Pin 1. Both the Trantor T128 and T130B come with
- an optional Boot ROM, which may or may not have the ROM chip in the socket.
-
- Switch & Jumper Settings:
-
- The switches and jumpers set the card address, ROM address, DMA channel,
- interrupt channel and other functions. The internal SCSI connector is
- located at the top end of the card, and the switches are located in one of
- the two following locations:
-
- - Below the connector, on the T128 host adapter
-
- -or-
-
- - To the left of the connector, on the T130B host adapter.
-
- The default position for all switches on the T128 and T130B is OFF.

- Summary of Switch Settings:
-
- Switch Function Setting
- --------------------------------------------------------
- SW 1,2,3, & 4 Reserved OFF at all times
- SW 5 Boot ROM Enable ON:enabled;OFF:disabled
- SW 6 Zero Wait-State Operation ON:enabled;OFF:disabled
- SW 7 & 8 Memory Address see below
-
- Memory Address:
-
- The T128 adapter works with one of four memory-mapped addresses. Switches 7
- and 8 select this address. The T128 adapter uses a single 8K address
- register beginning at the address selected by the switches.
-
- Memory Address Sw7 Sw8
- --------------------------
- CC00h OFF OFF
- C800h OFF ON
- DC00h ON OFF
- D800h ON ON
-
- The Switches 1-4 should remain OFF. Switch 5 enables the Boot ROM to permit
- booting from a device set to SCSI address 0. The Zero Wait-State can be
- enabled on AT-class or faster computers. This permits significantly faster
- operation of SCSI hard disks. "Zero Wait-State" refers not to memory, but
- to the speed of the bus itself. This switch should not be enabled until
- after the devices have been installed and tested thoroughly. Memory address
- of many 16-bit VGA cards may conflict with the default setting of CC00h. Be
- sure to consult the display adapter manual.
-
- One additional Jumper, JP1, located at the bottom near the adapter slot, is
- used for optional interrupt selection. If interrupts are selected in the
- software then the jumpers must be installed. Interrupts 3, 5, or 7 are
- available. There are 12 pins on JP1, and one jumper is needed. The
- following shows the settings.

- SW 6 Boot ROM Enable ON:disabled;OFF:enabled
- SW 7 & 8 Reserved OFF at all times
-
- I/O Address:
-
- The T130B adapter works at one of four I/O addresses. The T130B adapter
- uses a single 8K address register beginning at the address selected by the
- switches. Switches 1 and 2 select this address.
-

-
- Memory ROM Address:
-
- The T130B adapter works with one of four memory-mapped addresses. Switches
- 3 and 4 select this address. The T130B adapter uses a single 8K address
- register beginning at the address selected by the switches.
-

- Reserved ON OFF ON
- Reserved ON ON OFF
- Reserved ON ON ON
-
- Switch 6 enables the Boot ROM to permit booting from a device set to either
- SCSI address 0, 1 or 2. The Zero Wait-State can be enabled on AT-class or
- faster computers. This permits significantly faster operation of SCSI hard-
- disks. "Zero Wait-State" refers not to memory, but to the speed of the bus
- itself. This switch should not be enabled until after the devices have been
- installed and tested thoroughly. One additional Jumper, JP3, located at the
- bottom near the adapter slot, is used for optional interrupt selection. If
- interrupts are selected in the software then the jumpers must be installed.
- Interrupts 3, 5, or 7 or no IRQ are available. There are 6 pins on JP3, and
- one jumper is needed. The following shows the settings.
