Notice: Installing Red Hat 7.0 and later on a system where the (SCSI/ARRAY/NIC) controller board is not detected: Useful for the original Smart and Smart-2/E controllers where you have to specify the EISA slot number when loading the driver, i.e. the driver does not automatically detect the controller without specifying options to the driver. For Red Hat 6.2 and below we had used "linux dd" or "linux expert" to be able to key in options to driver when it was time to load them. For Red Hat 7.0 and later we now use "linux isa" to be able to specify options to SCSI, Array, and NIC drivers.

Notice: Setting the amount of memory in Linux kernel 2.4.x (Red Hat 7.1): The method for specifying the amount of memory you have when it is not automatically detected by the kernel has changed. The old format is to put mem=48M either as an append line in /etc/lilo.conf or to type it in at the LILO: or BOOT: prompt. Read memory.html to see the new format.

Notice: Usage of e100 or eepro100: If you are using the eepro100 driver, you should change over to the e100 driver from Intel. It seems that the eepro100 is not as stable as the e100. This driver is available for download from the Compaq website at the following web address:

Notice: Installation of Red Hat Linux directly to a Compaq Array Controller: Any documentation (whether here, or on Red Hat's Site, or on Compaq's site, or on - Chris Frantz's site - check*/ that states that you must first install to a hard drive attached to the embedded SCSI controller, then copy it to the array controller is definitely OLD and refers to a method that was to be used with Red Hat 5.2. The Linux kernel, since version 2.2.5, has had support for the Compaq Array controller built in. This means that any distribution based on the current Linux kernel (including but not limited to Red Hat 6.0 and newer) has support for directly installing to drives attached to the Compaq Array controller. The component pieces to make this happen is the cpqarray.o driver, an updated version of /sbin/fdisk, and an updated version of /sbin/lilo. These component pieces have since been added into the current kernel source and distributions.

Notice: Proper OS Choice when installing Linux: The preferred OS choice when installing Linux is now either Linux or UnixWare 2 instead of UnixWare 7. If the Linux choice (Dec. 1999 or 2000 firmware and SCU) is not available, then UnixWare 2 is the next and proper choice closest to Linux.
