I have installed RHEL4 on an Acer TravelMate laptop.
It was necessary to install from ISO's on the disk because the DVD-RW device is not being recognized in the install process... CD #1 can start the installation but then quickly no longer sees the device. Now that RHEL is installed, the DVD-RW device is still not recognized.
The boot process shows these messages:
ide0: I/O resource 0X1F0-0X1F7 not free
ide0: ports already in use, skipping probe
Probing IDE interface ide1 ...
hdc: ...., ATA Disk Drive
ide1 at 0x170-0x177, 0x376 on IRQ15
Hardware Browser -> IDE Controllers shows
Intel Corporation 82801FBM (ICH6M) SATA Controller
This same problem (not recognizing the DVD device) occurs with Fedora 3 and 4.
Red Hat 9 recognizes the DVD device correctly and can be installed entirely from CD. Once RH9 is installed, the Hardware Browser shows a CD/DVDW on /dev/scd0 and a hard drive on /dev/hdc and it can read data CDs OK.
Other distros (e.g. Mepis) work fine if the kernel used is 2.4.something but they don't work if the kernel is 2.6.something.
Some posts on LQ and elsewhere indicate that the problem occurs on other brands of computers, is related to SATA devices, and can be worked around by recompiling the kernel. I don't want to do that. Does anyone know how to fix this without a recompile? Is a fix from Red Hat coming soon?
