slackware disk failed to authenticate

[john connolly]

Hi,
I just bought a hp laptop with windows10 on it. I modified the hd to
allow space for slackware and altered the boot sequence so I could load
it off a disk but when I tried to boot I got the 'disk failed to
authenticate' message. One possibility (I guess because I haven't tried
it) is to further alter the boot info so it doesn't try to authenticate
the disk. I gather that there is some risk of malware, at least with
windows, if I do that. Is there another alternative?
Thanks, jwc

You need to check the laptop's UEFI (BIOS) settings and disable secure
boot, also sometimes referred to as as legacy boot.

Or, you might jes have a bad disc!

I've gotten a bad first CD in a purchased set from the Slackware
store, before. I hadda dwnld that first CD disc from a repository (I
usually use Utah State U) and burned a new ISO:

.....the rest of the discs in the set from the Slackware store
loaded/worked jes fine. A free alternative possible solution. ;)

Secure boot is not the same as (or the opposite of) legacy boot.
Legacy boot is boot in BIOS mode. Secure boot is an option of UEFI boot.
Forcing legacy boot will disable secure boot, but it will also prevent
to boot Windows if it was installed in UEFI mode.

Thanks for the replies. I am continuing this thread because I have
different problem with another hp laptop.
BTW, I did fumble through the installation that I asked about earlier.

Recently I received another HP laptop as a Christmas present. I have
installed the most recent slackware-current distro on it and it boots
with elilo successfully. My current problem is that I cannot get it to
find a wifi connection. It has the same Realtek wifi hardware
(RTL8111/8168/8411) as the other laptop. Dmesg tells me that the Gigabit
Ethernet driver 2.3LK-WAPI driver loads on BOTH laptops. However wicd on
the older laptop finds my wifi and connects successfully but the newer
one doesn't. It just reports that no wireless networks are found. Both
laptops report "mii 1 r8169" under lsmod, so AFIK they are both loading
the same module. I am really stumped here so any suggestions are welcome.
Thanks and Merry Christmas, jwc

RTL8111/8168/8411 is for ethernet (wired), not wifi.

That's ethernet, not wifi.

r8169 is the ethernet driver, not wifi.
Check with lspci if there is a wifi controller on the PCI bus.

Some laptops have a physical switch to disable wifi and sometimes they
might also have a bios setting to disable wifi. If you are unable to find
your wireless network with a laptop with a wireless card, first make sure
that the wireless card is really enabled.

Again, thanks for the replies. The laptop that works has an internal
Intel wifi adapter. I don't know what driver it uses but it must load
automatically. The new laptop that I am struggling with has a Realtek
wifi adapter. I found a 2015 debian source
(https://wiki.debian.org/rtl819x) that states that the r8192e_pci kernel
module is needed for Realtek 802.11n wireless LAN chips. For the kernel
that I am using, 4.9.67 #2 SMP, the module in question is present. I
tried to load it with modprobe but that didn't work. When I used insmod
I got an error message (unknown symbol in module). I don't know if this
is a wild goose chase or not, but that is where I am now.
BTW, using windows10 on this laptop gets me to the wifi source without a
problem, so this is not a hardware issue.
Thanks and blessings, jwc

Further info:

dmesg |grep firmware shows:

bluetooth hci0: direct firmware load for rtl_bt/rtl8723b_config.bin
failed with error -2

also, the output of lsusb shows: bus 001 Dev 002: ID 0bda:b009 Realtek
Semiconductor Corp.

and from the internet chatter I am not the first person to have trouble
with this adapter.

Happy trails, jwc

So the firmware is buggy or not the good one for this adapter.

~# slackpkg file-search rtl8723b_config.bin
Looking for rtl8723b_config.bin in package list. Please wait... DONE
No packages contains "rtl8723b_config\.bin" file.

It looks like this firmware is not part of Slackware...

Your card is rtl8723b or rtl8723be, not anything from 819x series. So the correct module to load is rtl8723b or rtl8723be (I do not know which but the error message suggests the b version. I had rtl8723ae on my 6 year old laptop and remember having headaches until kernels started to support it out of the box. My module is called rtl8723ae but it was called rtl8723a 3 or 4 years ago.

I think, either some of the files got corrupted during install or 4.9 has shaky support. I suggest you pick up latest kernels from current (4.9.x and 4.13.x) and upgrade your kernel before trying for other solutions.
