I made myself a boot disk from bootdisk.com along with several utilities to get my machine to work in DOS mode for a special project I'm doing.
Ideally I'd like to have two running serial ports on my system for project testing.
Unfortunately, only one is built-in and two are on a PCI card.
My computer I recently bought online (with the serial card pre-installed) is an IBM Thinkcenter 3 Ghz processor.
I'm lucky to get networking operations going.
I accessed my bios, looking for settings for the PCI serial ports, and it only allows me to control the one built into the motherboard.
The other two do not get recognized at all by the BIOS or even DOS. I checked this within QuickBasic (by looking up the serial port addresses in memory).
When I look at the card in detail, I see the following labels on it:
CE Tested to comply with FCC standards
MADE IN CHINA
NM9735 REV C
and on the back:
HS-IQ-P/I S/N No. T8 04110002380
And on one big chip soldered on the front, I see this:
So I'm curious, Is there any generic bios flashing utility that would make any bios scan PCI devices for presence of serial or parallel ports on PCI cards? If not, then is there a generic DOS driver I can install in autoexec.bat or config.sys that would make the PCI serial ports function as if they're real ports already embedded into the motherboard?
