I found this in my card collection and need some help in identifying exactly what it is and what I can use it for? I'm assuming its an XT IDE controller?

Thanks!

You can check with CheckIt or PCCONFIG if that BIOS is seen in upper memory area
and read what the card is described.

On the card you should find jumpers used for setting BIOS address
(maybe these 4 on the right-down corner).
You can use them to locate the BIOS of the card in free space in upper memory.
 
It's probably IDE-XT, as in the 8-bit variant of IDE used by the Tandy 1000 series, Olivetti Prodest PC1, and some other XT clones in the late '80s and early '90s... not to be confused with the XT-IDE, which is a card designed to allow use of (semi-) modern 16-bit IDE-AT / Parallel ATA drives in vintage XT-class machines.
 
Perhaps dumping the BIOS chip would yield more information. (And Modem7 might want to add the BIOS to his site)

The drive type is also sometimes referred to as "XTA" as opposed to the usual 16-bit "ATA".
 
hello
when searched the Conner CP3000 it states it is a "IDE /AT".
I think i did try a bigger disk on the controller - without any good result..
Perhaps the controller only supports disks not bigger then 40 mb ?! :)

Yes, I can add it to http://www.minuszerodegrees.net/rom/rom.htm
However, without the make and model of the card known, I will need a photo (so that people know what exactly the ROM image is from).
The photo at post #1 is too small.

Here's a little bit better pic. The upload keeps shrinking them, so let me know if you want a close up on just the ROM or anything else.

I have a 40mb Maxtor. Can I have a pic of your jumpers or was the previous pic how its setup now?
 
I actually got this working by copying the jumpers off a screen shot of Cimonvgs card with the Maxtor 40mb IDE. From the format routine, looks like it supports several larger IDE drives.

I have the photo, and the one that Cimonvg made, 'ready to roll'. [here]

All I need now is a file copy of the ROM. Do either of you know how to create one?

The preferred way of getting a ROM image is via an EPROM programmer. That is because sometimes, the content of the ROM is different to how the PC 'sees' it. An example is the ROM in an IBM EGA card. If someone created a ROM image file by using a program (such as DEBUG), and then used that file (unmodified) to make a replacement ROM, that replacement ROM would not work in an IBM EGA card.

But in most cases, the PC 'sees' the ROM contents exactly as it is laid out in the ROM.

The ROM in your IDE card is socketed, and you are asking for instructions. That tells me that you do not have an EPROM programmer. So, we will have to use a program.

The ROM in almost all XT-class hard disk controllers starts at address C8000, so we will assume that (for now at least). Your ROM is 32KB sized (a 27C256).

So use DEBUG in the following way to create the 32KB sized image file (named MYROM.BIN), and then email the file to me at temp6432836@outlook.com.au

C:\>DEBUG

-N MYROM.BIN

-R BX
BX 0000
:0000

-R CX
CX 0000
:8000

-M C800:0 8000 0100

-W 0100
Writing 8000 bytes

-Q

C:\>


BTW:
An alternate program is Mike Brutman's PCJRCART program. It creates a file for each ROM extension that it finds. Use it with the -noheaders option. Available from [here]. This will be unsuitable if the author of the ROM has incorrectly specified the ROM size at the third byte.
 
No its an IDE-AT controller in 8-bit form..

The harddisks that is connected to, is an AT style harddisk.. Maybe this controller can candle both by setting some jumpers.
