I am tired of seeing that penguin on top of my boot screen while Slackware is booting.
How could I replace it with a nice "S" slackware logo?

Has anybody done it already?

Why would you replace the Linux Penguin with the Slackware S, since you're booting the Linux kernel?

If you must, <Linux> Google being your friend, a search will tell.

...and how much time do you spend on your boot screen for you to get tired of it??
I guess you could go to gnome-look.org or kde-look.org and download a grub splash.

Download fblogo, you can get a version for Slackware from:
here

Create or find the image no more than 224 colors, and 80x80px size so that you do not disturb the messages shown by your distro at boot time.

You need not be too restrictive when creating the image: we will use another tool to convert it so that it meets the color-related prerequisites.

Save the image as png, and run the following:

pngtopnm logo.png | ppmquant -fs223| pnmtoplainpnm > logo_linux_clut224.ppm

cp logo_linux_clut224.ppm /usr/src/linux/drivers/video/logo/

Now configure your kernel, making sure that the following options are enabled (they can be found under the Device Drivers, Graphics Support subsection):
Support for frame buffer devices
VESA VGA graphics support
Video mode selection support
Framebuffer Console support
Select compiled-in fonts
VGA 8x16 font
Bootup logo
Standard 224-color Linux logo

That old fblogo for Slack-8.1 won't work on anything after that, but you can get a fresh package here:
