Subject description: 47 seconds to find puppy files
 

This is 4-TB hard drive, so I have to boot from a CD. (Puppy bootloaders won't work.) I have a 30-GB boot partition on the drive, and keep Tahr puppy files there in a dedicated directory, Tahr-6.0.5. There is another directory on this partition for Slacko 5.7. Both are frugal installs that boot from CD. While it takes only 12 seconds to find Slacko files, it takes 47 seconds to search for Tahr puppy files during the boot. Is there a setting where I can direct the search to look inside the dedicated Tahr directory?

something like this?
Code:
  kernel /DpupStretchOsc/vmlinuz pmedia=cd pfix=fsck psubdir=/DpupStretchOsc/ pdev1=sda9

Try changing the name of the directory to the name that is used when you do a frugal install.
Code:
tahr605_PAE
tahr605_noPAE

depending on which version you are using.

Also, change the name of the Slacko directory too.
Code:
slacko570PAE
slacko57NOpae

depending on which version you are using.

If the directories are on the first partition of the hard drive, they should get found quicker.

Hi nubc.

This is what I have for petihar's Triton, which is a tahrpup in essence.

The following lines find very quickly the "Triton" directory where all the files for this
tahrpup are.

I have regular quotes around the target directory, though; not diagonals ("/"),
like foxpup.
Code:
# 07
title Triton (définitif2), par petihar
root (hd0,0)
kernel (hd0,0)/Triton-6.0-def2/lance/vmlinuz quiet pkeys=cf pmedia=satahd root=/dev/ram0 pdev1=sda1 psubdir="Triton-6.0-def2" pfix=fsck,nocopy
initrd (hd0,0)/Triton-6.0-def2/lance/initrd.gz
boot

I also have the habit of putting the vmlinuz and initrd,gz files "in the basement"
of where the sfs files are. This is the tree of directory "Triton-6.0-def2":
Quote:
.
./lance
./lance/boot.cat
./lance/boot.msg
./lance/help2.msg
./lance/help.msg
./lance/initrd.gz
./lance/isolinux.bin
./lance/isolinux.cfg
./lance/logo.16
./lance/README.HTM
./lance/vmlinuz

./devx_tahr_6.0.5.sfs
./puppy_tahr_6.0.5.sfs
./tahrsave-babebi.2fs
./zdrv_tahr_6.0.5.sfs

(Before you ask, "lance" means "launch" in French.)
I am not sure this speeds up the boot, but I've been using such a structure for years.

Hopefully, this page will take the mystery out of it.

I hope this helps.

Changing the name of the directory had no effect on the long search for files. In fact I neglected to put the files in any directory at first, and still the search was 47 seconds. It would be pointless to change anything about the Slacko directory and files since those files are found in 12 seconds.

There exists a boot directory in the file system which contains a file named system.map, containing the assignments for the first 64k memories. Can I create a file in this boot directory to direct the search to the tahr directory? {Probably not useful]

A reminder: There is no GRUB or Grub4DOS on this computer. If you recommend text, kindly include a location for placing the text.

To totally understand.

What is on this CD you boot with?
How is it used to boot?
You do what?
You see what?

That 12 second search time indicates something is making it not search the entire drive.
That 47 second search time indicates it is searching the entire drive.

I changed the name a few times, and now the search time is 51 seconds. There is a fsckme.flg text file on the partition with the two savefile directories, and this text changes with the current OS, reading the last OS loaded.

The CD is the installation/liveCD that you burn from the downloaded ISO image. Please don't try to complicate the identity of the CD any further. The CD is nothing special, and the burn program has closed the disk. You can't write to this CD. I boot up the CD, get a Tahr 6.0.5 splash screen (at which point I can manually change boot parameters), then vmlinuz and initrd.gz are loaded, some file decompression, loading needed driver files, then follows the search for Puppy files.

So, what are you changing the boot parameters too?

I just say, it's a point in the boot that one can change the boot parameters, not that I am changing the boot parameters.

The Slacko search for files is now 36 seconds.

Probably just to spite you...

But seriously, have you looked at the settings for the lilo (or whatver the loader is
called when booting from CD)? Does it have the equivalent of the
< psubdir="/path/to/things/and/stuff" > setting that exists on GRUB4DOS?

If not, you add this parameter to the command line and you burn another CD.

You're not going to use that CD to boot on another machine, are you?

CD boots do search entire drives by design.

BFN.

musher,
I don't know what you're talking about, but I will reiterate that there is no grub, lilo, or grub4dos on this computer. Whether the CD has a bootloader, I do not know. The CD boots like a liveCD, only when it looks for files, it looks for tahr files saved to hard drive. not .sfs files on the CD. As far as I know, the CD is booted by the computer's BIOS and firmware.

Hi nubc,

You have frequently asked questions. You have frequently been asked by bigpup, "What do you do? What do you see?" If you've read bigpup's responses on other threads of questions asked by others, or perhaps yourself, he has explained the reason for those questions which I've sometimes either quoted or paraphrased as: "You are our eyes and hands. We can only know what you tell us. We can only try something on your computer if you do it."

You've told us that you boot Tahrpup using a CD with Tahrpup's files in a folder on your computer's hard drive. You have posted 6 time on this thread. You have still not told us what program you used to burn the CD, what bootloader was written to the CD, or what boot arguments exist on the CD.

To quote or paraphrase Donald Rumsfeld: "There are things we know. There are things we don't know. And there are things we don't know we don't know."

When something isn't working the way you think it should and you don't know why you should assume that most of the information about Puppy falls into the category of "things you don't know you don't know".

Just a hint: There are more ways than one to burn a CD.

I'm not new to Puppy, you can scold me how you like. I've been using Puppy for over 10 years. I use the program BurnISO2CD to burn the iso that I downloaded. Just like that, nothing extra. The same CD for installation and liveCD. If there are variations on burning boot CDs I'm not familiar with them.

On the CD, I see isolinux.bin, isolinux.cfg, boot.cat, boot.msg

mike, have you ever tried to boot puppy on a 4-TB drive? This has a GPT partition table. Traditional Puppy bootloaders won't work.

This is a standard installation/liveCD. No bootloader was written to the CD, and the burn program closed the CD, so I presume it's not writable.

THE CD IS THE BOOTLOADER

What bootloader is used to boot a live CD? Isolinux, is that the bootloader?
Maybe I should burn another CD, append isolinux?
