1.0.5 CD Boot in Panasonic CF-W2A fails if discontinuous

#1 Post by kethd »

My odd experience on Panasonic CF-W2A laptop (Intel 900MHz) is that booting from internal CD (DVD) works OK -- unless you pause at the HD-pupxxx question and let the CD spin down. Then when you continue, the CD fails to spin up and loading of usr_cram.fs fails with multiple error msgs about being unable to find various sectors.

Please let me know what additional specifics or experiments about this problem would be helpful.

I've tried to re-create the problem -- but I can't.
On the same computer, I rebooted a few times.
It takes 33 seconds for the UJDA747 DVD/CDRW drive to spin down at the <"Choose HD" (no suitable partitions) ...which partition has the pupxxx file...> question.
But now, whether I wait for spin-down or not, it spins up the CD and loads usr_cram.fs OK.
So it was either some random unpredictable glitch, or an interaction with the USB devices I was playing with previously.

The problem returned.
It does seem to be related to having USB devices plugged in at boot time.
With a USB mouse attached, and my new-used Buslink FDD1 USB 1.1 Floppy Drive, I again waited 33 secs for the internal CD to spin down, at the "Choose HD Partition" question. (Which has odd USB-related stuff appended.) When I hit Enter (for no pupxxx), it responded:
>...looking for usr_cram.fs on the CD.
The CD spun up, but just a little, weakly, and error msgs spewed:
>hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
>hdc: media error (bad sector): error=0x30
>end_request: I/O error, dev 16:00 (hdc), sector 0 (4, 8, 12)
Those 3 lines were repeated 4 times, for 4 sectors. Then it gave up:
>Uniform CD-ROM driver unloaded
