Thu Jun 30 20:26:57 UTC 2016 Slackware 14.2 x86_64 stable is released! The long development cycle (the Linux community has lately been living in "interesting times", as they say) is finally behind us, and we're proud to announce the release of Slackware 14.2. The new release brings many updates and modern tools, has switched from udev to eudev (no systemd), and adds well over a hundred new packages to the system. Thanks to the team, the upstream developers, the dedicated Slackware community, and everyone else who pitched in to help make this release a reality. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. Have fun! :-)

Welcome to the 09Slackware07 Linux custom USB boot stick!
|
||
|
||
By default, this stick boots a root Linux partition on $ROOT_DEVICE when you
|
||
hit ENTER. If you'd like to boot some other partition, use a command like
|
||
this on the prompt below:
|
||
|
||
mount root=/dev/sda1 ro
|
||
|
||
Where "/dev/sda1" is the partition you want to boot, and "ro" specifies that
|
||
the partition should be initially mounted as read-only. If you wish to mount
|
||
the partition read-write, use "rw" instead. To set the video console mode,
|
||
use the vga= parameter (press F1 to see a table). You may also add any other
|
||
kernel parameters you might need depending on your hardware, and which
|
||
drivers are included in your kernel.

STANDARD MODES:
|

To make the kernel prompt for standard video modes use: vga=ask
|

|

FRAMEBUFFER MODES:
|

To get the kernel to start in VESA framebuffer mode, you need to pass it
|
||
a vga= init string on the "boot:" prompt. Here's a table:
