18 neysx 1.52 The Quick install guide covers the Gentoo install process in a non-verbose
19     manner. Its purpose is to allow users to perform a stage3 install in no time.
20     Users should already have prior experience with installing Gentoo Linux if they
21     want to follow this guide.

37     This guide contains all commands you should use to complete a stage3
38     installation of Gentoo. You need a connection to the Internet to download the
39     stage3 and Portage snapshots.

43     Timing output follows all commands that take more than a couple of seconds to
44 nightmorph 1.63 finish. Commands were timed on an AMD 2000 1.66 Ghz PC with 512 MB of RAM and
45 neysx 1.52 two SATA disks connected to a hardware controller.

75     Download a CD from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>.
76 neysx 1.52 You can find the minimal CD ISO in
77     <path>releases/x86/&lt;release&gt;/installcd</path> or the LiveCD ISO in
78     <path>releases/x86/&lt;release&gt;/livecd</path>. The <e>minimal</e>
79     installation CD is only useful for Internet-based installations. You can use
80     the <e>LiveCD</e> to perform a networkless installation as documented in the
81 neysx 1.73 <uri link="/doc/en/handbook/2007.0/handbook-x86.xml">2007.0 x86 installation

95 swift 1.38 <p>
96 neysx 1.52 Press
97     <c>F2</c> at the boot screen to find out what boot options exist. You can
98     either start <c>gentoo</c> or <c>gentoo-nofb</c>, the latter disables the
99     framebuffer. If you booted the LiveCD, don't forget to add the <c>nox</c>
100     option to prevent the X graphical environment from starting. Several options
101     allow to enable or disable some features. If all goes well, your hardware will
102     be detected and all modules will be loaded. If the kernel fails to boot
103     properly or if your computer hangs during the boot procedure, you may have to
104 neysx 1.62 experiment with different configurations. The safest way is probably to use the
105 rane 1.55 <c>nodetect</c> option and then load required modules explicitly.

141 swift 1.1 <body>
142    
143     <p>
144 swift 1.38 If your network does not work already, you can use <c>net-setup</c> to configure
145     your network. You might need to load support for your network card using
146     <c>modprobe</c> prior to the configuration. If you have ADSL, use
147 nightmorph 1.59 <c>pppoe-setup</c> and <c>pppoe-start</c>. For PPTP support, first edit
148 swift 1.38 <path>/etc/ppp/chap-secrets</path> and <path>/etc/ppp/options.pptp</path> and
149     then use <c>pptp &lt;server&nbsp;ip&gt;</c>.
150     </p>
151    
152     <p>
153     For wireless access, use <c>iwconfig</c> to set the wireless parameters and then
154 swift 1.44 use either <c>net-setup</c> again or run <c>ifconfig</c>, <c>dhcpcd</c> and/or
155 swift 1.38 <c>route</c> manually.
156 swift 1.1 </p>
157    
158     <p>
159 swift 1.44 If you are behind a proxy, do not forget to initialize your system using
160 swift 1.38 <c>export http_proxy</c>, <c>ftp_proxy</c> and <c>RSYNC_PROXY</c>.

168     Alternatively, you can start networking manually. The following example assigns
169 rane 1.55 the IP address 192.168.1.10 to your PC and defines 192.168.1.1 as your router
170 neysx 1.52 and name server.

207     <p>
208     Now, set the root password on the liveCD so that you can connect to it from
209     another PC. Please note that allowing root to connect over ssh is not
210     recommended under normal circumstances. If you can't trust your local network,
211     use a long and complex password, you should use it only once as it will
212 rane 1.53 disappear after your first reboot.

244     Use <c>fdisk</c> or <c>cfdisk</c> to create your partition layout. You need at
245 neysx 1.52 least a swap partition (type 82) and one Linux partition (type 83). The

247     as used in our handbook. The device name is likely to be either
248     <path>/dev/sda</path> for a SATA or SCSI disk, or <path>/dev/hda</path> for an
