I/O Card Jumper & Software Settings
Identifying the I/O card
There have been five different I/O cards used in the Sable computers as of April 2000. The original card
used was the STB DSP/550 which has two DB9 ports and is ISA. The next card was the SIIG Serial Expander
4S which has one DB9 and one DB25 and is again ISA. The original PCI card used was the SIIG Dual
CyberSerial PCI controller which has two DB9 ports. The SIIG Single CyberSerial PCI controller has only one
DB9 port per card. Currently, the LAVA SSerial-PCI card is being used which also only have one port.
STB DSP/550
The first I/O card installed in PCComplete’s Sable PCs was the STB DSP/550 I/O card. This ISA card sup-
ports two serial and one parallel port (though only the serial ports are enabled for the Sable configuration).
When the card is configured this way, Windows NT should have the following port settings:
COM IRQ Address
1 4 3f8
2 3 2f8
3 5 3e8
4 9 2e8
It should also be noted that with this configuration DOS and Windows95 will not be able to use COM4.
