Need Help Installing Legacy System on Newer Hardware
We have a legacy software application that runs on SCO OpenServer 5.0.6, and the current server (built around 2003-04) is still running. I have been attempting to upgrade the hardware, to hopefully increase the time that we will have access to the data in this system, but am running into an apparently common problem with the SATA controller driver.
The server I am attempting to use is from about 2008, has a SuperMicro X7DVL-E motherboard, with an Intel ESB2 SATA controller. The best advice I can find using Google is to try and use the ad320_btld driver that I've found on the SCO public ftp site. However, when I try to install using this, it never appears to get installed correctly. When it lists the devices at the point of beginning to install, it still shows the adapter as "wd", and says that there is no disk detected for installation.
First question is - am I wasting my time, and this will never work?
Second question is - what might I be doing wrong when trying to install the ad320_btld driver? I insert the separate floppy that I have copied the downloaded image file to, but I never get asked if I want to "replace" the wd driver.
Any help would be appreciated - Thanks!

is equal to:

NAME
tws -- 3ware 9750 SATA+SAS 6Gb/s RAID controller card driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device scbus
device tws
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
tws_load="YES"
DESCRIPTION
The tws driver provides support for LSI's 3ware 9750 SATA+SAS 6Gb/s RAID controller cards.
These controllers feature the LSISAS2108 6Gb/s SAS RAID-on-Chip (ROC) and are available in 4- and 8-port configurations, supports RAID levels
0, 1, 5, 6, 10, 50 and single disk, with 96 SATA and/or SAS hard drives and SSDs.
For further hardware information, see http://www.lsi.com/.
HARDWARE
The tws driver supports the following SATA/SAS RAID controller:
o LSI's 3ware SAS 9750 series
LOADER TUNABLES
Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.tws.cam_depth The maximum queued CAM SIM requests for one controller. The default value is 256.
hw.tws.enable_msi This tunable enables MSI support on the controller if set to a non-zero value. The default value is 0.
hw.tws.queue_depth The maximum queued requests for one controller.
hw.tws.use_32bit_sgls Limit the driver to use only 32-bit SG elements regardless whether the operating system is running in 64-bit mode.
The default value is 0.
FILES
/dev/da? array/logical disk interface
/dev/tws? management interface
DIAGNOSTICS
Whenever the driver encounters a command failure, it prints out an error code in the format: "ERROR: (<error source>: <error code>):", fol-
lowed by a text description of the error. There are other error messages and warnings that the driver prints out, depending on the kinds of
errors that it encounters. If the driver is compiled with TWS_DEBUG defined, it prints out a whole bunch of debug messages.
