Red Hat 7.3 Installation can't see Samsung cdrom--can't continue installation

I'm trying an install of Red Hat 7.3 on a custom machine. I can boot off of the installation CD, but after initating the install (and entering language and keyboard) I'm asked what kind of cdrom I'm using (SCSI, or other CDROM). I find this strange that the cdrom is visible to the bios in order to boot, but not visible to Red Hat during the install. The cdrom is an IDE Samsung 152-G. It's an Intel 2.8 GHz with 2GB of RAM. Integrated Intel 865 board..

I've tried booting from "boot: linux dd" and using the 'oldcdrom.img' from the installation CD as a driver disk. It appears that the cdrom becomes visible, but then it tells me to insert the Red Hat Installation's already in there.

I've also tried the "boot: linux hdc=cdrom" but that just leads to a kernel panic. (I've also tried hda, hdb, hdd, just in case--all give the same result.)

Has anyone seen this before? Are there compatability issues of which I'm unaware?

Try switching consoles ( ctrl-alt-F2 ) and type dmesg. See if it detects your cdrom upon bootup, etc and post that info here, etc.

can't ALT-CTRL-F2

I can't ALT-CTRL-F2.

I can ALT-CTRL-F3 and F4, but the information there isn't particularly illuminating...although I do see a message (among others)
* modules to insert ide-cd
* module(s) ide-cd not found
* load module set to done
* modules to insert scsi_mod sd_mod sr_mod
* inserted /tmp/scsi_mod.o
* inserted /tmp/sd_mod.o
* inserted /tmp/sr_mod.o
* load module set to done

That seems to suggest it's trying SCSI emulation. I tried to fool the installer, then, and tried to load the SCSI support modules to see if that would work. They all behaved the same (Loading driver, initializing CD-ROM), but then kicked me back to the "What type of CDROM do you have?" question. I did notice that when I tried the "All DMA-capable DPT SCSI (dma mode) (eata_dma)" driver it took longer while 'loading driver' and 'initializing', but it still kicked me back to the "What type of CDROM do you have?" question.

If it means anything to you, I tried a Debian (woody) install. I used a RESCUE floppy, ROOT floppy, and in the boot sequence for that it clearly recognized my CDROM and hard drive. I was able to get a base installation from the CD.
