Hi!!!

I am a newb with Puppy. I burned the 2.12 ISO (MD5 verified...) on a CD-R. It refuses to boot on my PC. I have tested it on 3 other PCs and it works fine!! On my PC which is homebrew with following data:

Albatron PX875P Pro V2.0 (i875P/ICH5) + P4/Celeron (not Celeron D, hence no Prescott core...) 2.6GHz/FSB400 + 4x512MB DDR333 Transcend DIMMs (dual channel)+ Albatron NVidia GeForce FX5200 AGPx8 VGA + Seagate ST3200822AS 200GB SATA HD + SAMSUNG SP0411N 40GB PATA HD mounted via a PCI UATA controller (SiL0680 Medley based...) + Teac CD-W552G CD-R/W + NEC ND-3550A DVD-R/W + std floppy + std PS/2 keyboard + Logitech compatible PS/2 trackball on a Philips 170T4 monitor.

CD-R begins to boot normally (default boot...), then reaches:
"Now executing 'init' script in initial-ramdisk"
"Loading kernel modules... done"
"Looking for Puppy in done"
"Looking for pup_save.3fs in hda1... sda1... scd0... scd1... sda1 done"

and then crashes with error:

"ERROR cannot find Puppy on 'idecd' boot media.
PUPMODE=1 PDEV=
Exited to initial-ramdisk (/dev/ram0)"
and then I just get the prompt ("#") (with message "...guru can debug...", etc.).

The same CD-R I tried (and worked perfectly) on 3 other PCs ranging from a 3 year old P4/Northwood on a Chaintech i845PE based mobo with 2GB of RAM to a VIA KM266/ CeleronD with 512MB RAM and even a fresh Athlon64 on an NForce4 mobo with 2GB of RAM...
Any clues about this???

P.S. The same machine that Puppy will not boot, I tried with SUSE 10.0 LiveDVD and boots without any problem...Oh, also on both HDs filesystem is NTFS. Native OS is Win2k/SP4


Many Thanks in advance

maybe puppy is not compatible with ur ram?¿

i dont know, but when u boot puppy from the cd it runs totally in ram, u couuld run puppy without hard disc... so.. we should start analizing the problem from there...


good luck

Try copying the pup_212.sfs file from the CD to the root of your hda1 partition and rebooting.

Puppy is having Probs locating your drives:
BTW - are Sata & Pata hard drives on an "add-in" controller ?

What does
Code:
 fdisk -l
> show Re locations & drive letters (hd- ???)
Which optical was used to boot - for ease of detection:
cable first IDE contoller for hard drives, second for opticals -
In that manner, flawed probe scripts are aided in probes.

(Dev/hdc would be 2nd controller, primary)
Normally (to Linux) that would not matter - but all depends on how any boot or install script probes, ID's locations.

When it exits to CLI prompt - use output of fdisk to tell Puppy
full path to CD disc containing the sfs files

HTH

PostPosted: Wed 29 Nov 2006, 21:50    Post subject: RAM incompatibility???  

Confused RAM incompatibility?? That's a strange one, I say... The Chaintech, i845PE-based mobo PC I tried (and worked...) has also Transcend DDR333 DIMMs. It sounds a bit strange to be something to do with RAM. Analyzing the data I have (and NOT being an expert...), the interesting part is the "...cannot find Puppy on 'idecd' boot media..." message. Since - apparently - Puppy IS INDEED on the CD-R, there must be something wrong with the device handling/enumeration. Since Puppy exists, the initialization procedure searches in the wrong place...Well, I don't know...I need definitely more feedback on the way CD Puppy boots, i.e. when it reaches the point of the crash event what exactly has taken place concerning boot-up procedure? Are there any logfiles to look for?

I was thinking along similar lines Gn2 (and we were writing simultaneously it seems Smile ). I need some time to check...I am writing from the target PC...will revert ASAP. SATA HD is connected directly to mobo. PATA is connected via the UATA-133 controller. Primary HD is SATA. If I remember correctly (let me peek through the window...) CD-R/W and DVD-R/W share same IDE channel, CD-R/W is master, DVD-R/W slave. I don't remember if it is IDE1 or IDE2 but anyway the other IDE is unusable because i875 (this is an Intel trick...) emulates SATA as being "the other" IDE channel. That's why to use another PATA drive, I could not connect directly, and had to resort to the PCI connection.

This is no HD installation. It is Live-CD only...
Tried the fdisk -l and found some interesting results
It lists my 2 HDs as following:

My 40GB PATA HD which is normally my secondary disk is listed as dev/hda1
My primary 200GB SATA disk is dev/sda1

Should I see in fdisk -l the optical drives as well or not?

To guestimate, scd0 and scd1 would be the optical drives (or at least were the script supposes that they are...). How can I check this?

It wouldn't make much sense in recabling. SATA has only one place to go. This leaves effectively only one IDE channel and leaves 2 opticals + PATA HD hence UATA PCI controller needed. Since PATA HD is only secondary, I keep the native available IDE channel for the opticals. I think it would be rather error prone to mount any of the opticals on the PCI controller...I am also not favoring mounting HDs and opticals sharing common IDE channels. Don't know if anyone had stable systems using this set-up, I usually prefer NOT sharing channels between opticals and HDs.

At the point that the script crashes it is looking for pup_212.sfs on the Live-CD, am I right?

you can type:

fdisk -l /dev/scd0 /dev/scd1

probedisk is the program that would probably be used to detect your drives ... just type probedisk

i don't think Puppy has support for scsi drives yet ... i don't think Puppy can boot from a scsi cd drive

/dev/scd0 and /dev/scd1 means that the opticals are regarded as SCSI??? (very weird!!!...will check)

Correct - Puppy initrd image cannot locate the optical holding your booted CD disc - & only the hard drives are listed via fdisk
Code:
Dmesg|less
will give boot probe results
(That odd lookng vertical seperator in above - "pipes" output so Msg may be paused & read.

Or > (lscpci) may show (puppy includes some other tool never noted before) uhid or something ?

"Re-cabling" > nor altering BIOS boot sequence > should never be needed !

Please try dmesg output to ID your opticals,
"point" Puppy to device used to boot the liveCD -

Mount manually if needed
Code:
 mkdir /hd_xx
  mount -t iso9660 /dev/hd_xx  /your_created_mount_point


BTW - HOW did my post get placed a few down - when first viewed - no other had yet replied ?

More than the B/B is acting up !

well, Puppy might think they are scsi drives, or at least that they need scsi emulation, which might be about the same thing ... on a typical pc with ide drives, the hard drive would probably be /dev/hda and the optical drive might be /dev/hdc

i don't know if you can type "disktype /dev/scd0" if you get a command prompt when Puppy crashes, it might give you some information

Yes!!! Mystery is just beginning to unravel...Checked with probedisk, test-eide and test-scsi and for some reason Puppy thinks CD-R/W and DVD-R/W are SCSI devices!!! At this point I need some serious help to fix this...

The thread sequence changes faster than I can type Laughing Tks Gn2 will try ASAP. They are indeed /dev/scd0 and /dev/scd1...
