During installation of Red Hat Linux, there are some limits placed on the
filesystems and other drivers supported by the kernel. However, after
installation there is support for all file systems available under
Linux. At install time the modularized kernel has support for (E)IDE
devices, (including ATAPI CD-ROM drives), SCSI adapters, and network
cards. Additionally, all mice, SLIP, CSLIP, PPP, PLIP, FPU emulation,
console selection, ELF, SysV IPC, IP forwarding, firewalling and
accounting, reverse ARP, QIC tape and parallel printers, are supported.
Please Note: Because Red Hat Linux supports installation on many different types
of hardware, many drivers (including those for SCSI
adapters, network cards, and many CD-ROMs) are not built into the Linux
kernel used during installation; rather, they are available as
modules and loaded as you need them during the installation
process. If necessary, you will have the chance to specify options for
these modules at the time they are loaded, and in fact these drivers will
ignore any options you specify for them at the boot: prompt.
After the installation is complete you may want to rebuild a kernel
that includes support for your specific hardware configuration. See
Section 11.6 for information on building a customized
kernel. Note that, in most cases, a custom-built kernel is not necessary.
