Well, yes, if it is a PCI board. But below you say it's an ISA board, and
therefore it won't work with the NCR driver. The NCR chips are PCI-only.
(at least the ones supported by the ncr driver)

Sounds like some sort of DTC chip, as opposed to another vendor's chip.
Unfortunately none of that translates into a DTC card model number..

Well, at least for PCI boards, it's pretty easy to figure out. Boot a
GENERIC kernel and see what gets probed.

I mean just the info you gave me above.

Well, there are several possibilities:
1. The card you have is compatible with Adaptec 1510/1520 boards, like the
newer ISA boards on DTC's web page. If that's the case, you're out of
luck, since the aic driver hasn't been rewritten for CAM.
2. The card you have uses a DTC proprietary interface. If that's the
case, there's no driver for it.
3. The card you have is compatible with Adaptec 1540/1542 boards. There
was apparantly a DTC EISA card that was compatible with the Adaptec
1540. At least we claim to support such a card in the release notes.
If that's the case, you may be able to get it to work.
To test out #3, you'll need to configure a kernel with the aha driver.
Booting a GENERIC kernel will probably be sufficient.
If the card is PNP, it should be detected and configured by the pnp code.
If not, you'll probably need to configure the aha driver in your kernel
config file with an I/O port, irq and DMA channel.
My guess is that #1 or #2 applies to your card.
