Is it possible that I can have a physical cd rom device, which bios recognizes as a ide cd drive, but have it boot a iso/image file from flash storage ?
Its not feasible for me to have real cd drives , considering the cost of the project, and the power consumption as well.
Also, the bios of the boards am supposed to boot into, is locked into booting cdroms only. It can't boot a sata/usb device at all.

I have no idea whether or not its IDE emulation, or some other kind of emulation, but ISOSTICK has this functionality.
You can use the included software for ISO >4gb to transfer your ISO to the SD card you plug into the side. ISO less than 4gb can be copied and pasted directly to the SD card.
The optical drive is one drive letter, and the flash drive is another.
You can boot from the virtual CD/DVD drive directly from the BIOS, I do it all the time.

you can still buy IDE flash drives from e.g. Transcend. those are specified for embedded system. I would expect those to be expensive though.

You need a device presenting an ATAPI interface instead of an ATA one. Memkor seems to produce such a device: http://www.memkor.com/en/products/cfdrives/142atapi.html
As explained on their website they can emulate removable devices by using a special compact flash adapter.

I already tried using a DOM, ide flash drive. Doesn't work. Only normal ide cd drive works. – Dragunov – 2010-12-17T11:26:18.410
