I want to install Gentoo on a laptop based on the Intel Atom x5-Z8350 processor. This laptop has a combined wifi / bluetooth adapter rtl8723bs that is not detected during boot of Minimal Installation CD.
How do I connect this adapter during installation?

Max77,

Welcome to Gentoo.

You don't use the Gentoo install CD to install your Gentoo.
Its only a toolkit, none of its code goes into your install. Use any random Live distro you have to hand.
Even use another Linux you have installed just now.

Become root, do
Code:
mkdir /mnt/gentoo
and follow the handbook.
That's the only extra step you should need.

There is also the sneakernet option.
The method will work but some of the detail has changed over the years.

NeddySeagoon, thanks for the advice, I'll try, but maybe it’s easier for me to compile the adapter driver on another PC, for example on a virtual machine, and apply it during boot?

Max77,

That's non trivial.

You need identical versions of gcc and the kernel sources that were used to build the original kernel, or the kernel will reject the module, so its likely you will end up doing a whole Gentoo install on the VM, then learning some of the finer points of portage so you get the right versions.

I am going to make two points here.

Point one, it is easier to get a minimal version of Gentoo up and running first. Once it is running and you can make inquiries then you can get your adapter rtl8723bs working. The only thing that can complicate that model is, if the only you can connect your keyboard/internet through that interface. If you can access the internet through wired Ethernet, I would suggest that. Most wired interfaces are well supported by Linux. If you only have access to wifi internet, then a USB wifi stick might work for you. The only caveat I have with USB wifi interfaces is, you almost never know before you open the box, which diver Linux needs for it. I almost suggest using a live distro to detect the USB wifi stick before trying to install Gentoo. I would also suggest using a wired keyboard to do the install. Once installed, you can debug your rtl8723bs and then use your preferred connection.

Point two, to see how well the Linux kernel supports a device, it might be easier to install to boot up with a live distro and see if that distro can detect a devise and get it functioning. If they do get it working you can use them as a way to figure out how to configure Gentoo. I personally like Linux Lite and Finnix as live distros, but Finnix has not been updated in a few years, so some of the newest hardware might not be detected. Knoppix is still active, but it's been years since I've used it. But I do remember it was quite well at detecting.

I do have one question, have you worked with a Linux distro before using Gentoo? I feel that Gentoo is really a distro for advanced Linux users. Unless you have worked with other distros, I think the learning curve is too steep to use Gentoo as your first Linux distro. I think you should have some experience with basic Linux concepts before trying out Gentoo.

I became interested in Linux from the Ubuntu and Mint distributions. Then switched to Arch Linux.
Arch Linux has been on this laptop for a long time, but now I want to install Gentoo in order to maximize its capabilities and throw out everything that is unnecessary.

Max77,

Make some space for Gentoo.
Boot Arch, and as root do
Code:
mkdir /mnt/gentoo

Follow the handbook. Make a dual boot system if you like.

When you stop using Arch, throw it away and donate the space to Gentoo.

There is no need to install Gentoo in one sitting. You can get back to where you left off with your install.

Did those other distros allow you to get the rtl8723bs up and running? Do you have a keyboard and internet connection that works without the rtl8723bs? The way Gentoo installs you can build a kernel early on. (in fact, it almost insists on it). The only part that might be tricky is how to get all of the dist-files you need onto the HD without a net connection.

To do so, you would first need a portage tree. Then using "emerge --pretend --fetchonly [packages]" will generate a list of URLs that you can download the dist-files with. The list can be confusing because each line is the same dist-file with multiple sources. You hand DL each by hand, but it is much easier if you have a script to DL the dist-files for you.

PS after looking at NeddySeagoon's (the true expert) response, I can see that if you can boot with Arch then chroot into Gentoo. Assuming that the net and keyboard work for Arch, they will work with Gentoo in chroot mode. You can fetch all the files you need portage-tree and dist-files. You can compile the new kernel and even packages while in chroot mode.
