Bigpup look here for the mods that GalliumOS installs on the OS side for that chipset.

https://github.com/GalliumOS/galliumos-baytrail

I'm wondering if you do the same audio-related changes to Bionicpup64 manually, would the kernel that ozsouth provided for you then work to provide working sound?

The page shows files in /etc /usr, /var/lib/alsa , etc.

One difference, the asound.state file in GalliumOS /var/lib/alsa exists in /etc on puppy.

I'd make a backup of the current puppy files before modding during a test.

Just a stab in the dark, here......

@bigpup - after seeing what difference pulseaudio base files made to sound detection on my system & seeing a pulse folder at the gallium github, I wonder if full pulseaudio might help this cause. The /etc/pulse folder's .conf file refers to pulseaudio daemon in /usr/bin - but it isn't in bionicpup64.

Have not had chance to try it yet.
I too noticed the Pulse stuff.

I guess I will add Pulsaudio to Bionicpup64 8.0 and see.
Really was not wanting to have to use Pulse, but if I must. Rolling Eyes

But, I wonder if this is just making Puppy have what gallium is setup to use, not what Puppy uses for sound. Idea

I am really needing to do other things, right now.
But I will report back results.
Life is getting in the way! Laughing

I've received my used Acer C720-2844 today.

Tried it on Bionicpup64 -- starts up but touchpad is inoperable, keyboard works.

Looks like there is no synaptics driver. The touchpad is a Cypress APA Trackpad

It works in FatDog64-810. Although bootcodes are required to boot Fatdog 810:

mem=1950m (required because otherwise it reports image size is too large for memory)

and possibly: tpm_tis.interrupts=0 nmi_watchdog=0 (not sure if needed)

These bootcodes were al found in the FatDog64-631-Acer-C720-only ISO.

Sorry Bigpup, but I didn't see your post today before I decided to open the back, remove the write-protect screw and flash MrChromebox Full ROM. (I had been using MrChromebox legacy boot before.)

The full ROM cured the touchpad problem and everything works now, including sound.

I'm still runnig off of a USB thumbdrive, but would like to now do a frugal install.

But the disk has a lot of weird partitions -- I'd like to start over with gparted cleaning everything up and repartitioning, but I'm not sure if any of them are needed to boot now.

Also, Bionicpup64 says it isn't UEFI compatible, and MrChromebox says Full ROM is UEFI only. Not sure if I'm misinterpreting these two statements....

I figured the bios needed to really be replaced, with MrChromebox Full ROM, to really get the Chromebook to work like a normal laptop.

I have not tried the replacement yet.
Believe it of not, my write-protect screw is not wanting to come out easily. I may have to drill it out Rolling Eyes

A HP Stream laptop I have..
It has normal UEFI bios.
I totally removed Windows 10s, on internal SSD drive, completely new partition table (msdos), new partitions and formatted.
Keeping with standard UEFI requirements.
First partition small 500MB, formatted fat32, flagged boot.
Use this as the boot partition to hold all the boot loader stuff.
Rest of drive, whatever partitioning you want. Did use ext formats.

I used Frugalpup installer to do a frugal install of Bionicpup64 8.0.
http://www.murga-linux.com/puppy/viewtopic.php?t=114340
Make sure to get the latest version.
Installed Bionicpup to one of the ext formatted partitions.

Warning:
If you updated Bionicpup64 8.0 using Quickpet->Info->Bionicpup updates.
It installs Frugalpup, but an older version.
All the Frugalpup downloads are sfs packages.
Loading the sfs will not over ride the already installed frugalpup version.
To use the Frugalpup sfs in Bionicpup64 8.0
Change the sfs to a pet package.
Install it into Bionicpup.


Used Frugalpup's boot installer to install a boot loader to the first partition.
Frugalpup has several different boot loaders it can install.
One is UEFI.

I installed the UEFI boot loader, kept the UEFI bios normally setup (Secure boot enabled)

Bionicpup64 8.0 boots with no problems.

This is probably what I will do if I can ever get this write-protect screw removed.
Not happy about maybe having to us a drill and slinging metal pieces, inside my Chromebook.
I may have to try the old cup trick.
Tape a paper cup around the screw to catch the metal pieces.

Maybe this will work for you.
Others I have seen, used the MrChromebox Full ROM and have no problems booting. However, not exactly sure there boot loader setups.
If it boots from a USB using MrChromebox Full ROM.
A internal drive frugal install using a UEFI boot loader should work.

Thanks BigPup!

I already have the latest BionicPup64 -- that's the one I have installed on the USB thumbdrive, and have it working with the Acer C720.

So what I'm hearing is just use Gparted to delete the present partitions, change device from GPT to MBR and then set up 500mb partition 1, set the boot flag. Rest of drive will be ext2 partitions (non-journaling partiton to extend the life of the SSD). And no swap.

Use latest Frugalp\Pup to do an UEFI install, secure boot.

Instal Bionicpup64.

Yes.
Important that first partition is fat32 format.

Not sure if MrChromebox Full ROM is a fully secure boot UEFI.
You have used it, I have not.


But Frugalpup does install a good UEFI boot loader that works with UEFI bios.
Make sure you install the boot loader on the first partition.

For UEFI booting using the UEFI boot loader.
On first boot:
There is a setup you have to do. It requires the "enrolling" of a MOK (Machine Owner Key), with MOK manager.
The Puppy MOK is contained in the file "/puppy.cer" in the fat32 boot install partition.
Documentation of the "enroll" process is included in FrugalPup's "Help" facility.
Only needed one time at first boot.

I wish gyro would name Frugalpup installer to some other name.
I do not know how many times people think I am talking about some new version of Puppy and not just a program for doing frugal installs.

Frugalpup has option buttons on it's main window.
You can use them to do everything.
Gparted to setup drive.
Install Puppy version.
Install and setup boot loader.

Thanks Bigpup it went smoothly!

Although I forgot about (or missed the option for) secure boot. But everything works fine including sound.

And instead of about 15 partitions, I now have two, Boot, and Puppy (ext2).

This is great, especially after the torture of the Acer R11 on GalliumOS. I don't mean to knock that OS, and am actually grateful those guys put in so much work to make a functioning Linux for most Chromebooks.

But on the Acer R11 specifically, the mousepad was nutz, the desktop drive icons never worked, the partition and thumb drive UUID names inconvenient, etc. etc.

And then the struggles to try to get Puppy to work on that box, mousepad, sound, etc....

Now with the Acer C720 and Puppy I'm back to easy and familiar ground. Everything works!!!!

It really is a 2 year sigh of relief!

I was hopping Frugalpup was a installer to use that would just work.

Could you work up a how to guide on what you did.

I need some info to post on how to do the MrChromebox Full ROM install, delete what is on the internal drive, and setup and install Puppy.
I will put the information here:
http://www.murga-linux.com/puppy/viewtopic.php?p=924306#924306

Now I know I should get this MrChromebox Full ROM on my HP Chromebook.

These are the steps I took to modify an Acer C720-2844 Chromebook to become a Puppybook. Please note that this removes the Chrome operating system completely. Please also realize that this works specifically for this computer and model, and may not require the same steps, and or may not produce satisfactory results with any other Chromebook. My computer has 4GB of RAM memory and a 16GB SSD hard drive.

1.) I prepared a USB thumbdrive with a current (not updated) bootable Bionicpup64 installation. I added a current FrugalPup-20.shs puppy installer. This would be needed later when installing Puppy.

2.) I did a Startpage lookup for “C720 write protect screw” and found an online photo showing its location on the computer's motherboard. I removed all screws from the bottom of the computer's plastic case, and carefully worked the bottom loose by lightly prying out the edges..

3.) I removed the write protect screw, and re-attached the case with the screws.

4.) I booted the computer as a “guest” (I have never set up a Google acct on this box) then hit <CTRL> <ALT> <T> to open a terminal.

5.) To enter the shell I entered:

Code:
shell


6.) Before rewriting the ROM, I familiarized myself with the options explained at the mrchromebox.tech website. To download and run the Mr Chromebox configuration script I entered the following, (note -LO is capital letter O, not zero):
Code:
cd; curl -LO https://mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh


7.) I chose option 3, “Install/Update Full ROM Firmware”.

8.) I backed up the old firmware on separate USB drive when asked. When the script finished I exited.

9.) I booted the computer with the BionicPup64 USB drive (from step 1. above) attached, and hit <ESC> at the boot screen, then selected Boot Menu, and then selected the USB drive to initiate the boot. Puppy started up.

10.) I ran <Menu> <System> <Gparted> for device sda. I deleted every partition on the drive, one by one.

12. I clicked <Device> <Create Partition Table> and accepted the “msdos” default type (mbr).

13. I created a first new partition of 500Mb using a FAT32 type, named “BOOT”.

14.) When that was created, I right-clicked on the partition, then chose “flags” from the menu and then set the “boot” flag.

15.) I partitioned the rest of the drive as ext2 (because I wanted a non-journaling type to lengthen the life of the SSD drive. Likewise I didn't create a SWAP partition.

16.) I closed Gparted, and selected Install Puppy from the FrugalPup-20 installer menu. (Or depending on how you start the program you may have to run the Frugalpup installer by going to <Menu> <Setup> <Diskpup> ).

I entered the Puppy files source as “directory” and pointed to /mnt/home/bionicpup64 (the original files on the USB drive). (I believe you could also choose “This” from the menu to do the same thing.)

17.) I installed BionicPup64 to the second partition, in a new subdirectory I called “Bionicpup64”.
I also located the personal save folder as my new “Bionicpup64” subdirectory.

18.) After doing the Puppy install, I chose UEFI and to install the boot to UEFI on partition 1 (hda1).

19.) After all the questions were answered and the installation completed I re-booted, and the new puppy system started up correctly.

20.) After downloading several applications, I noticed that my trackpad started to lag and stick. I opened <menu> <setup> <Mouse/Keyboard Wizard> <Touchpad> and increased the sensitivity by moving the slider left (lower number) to 16, then saved it, The pointer now acts normally again.
