[parisc-linux] HD not bootable after installation....

[Pedot, Wolfgang]

Hi,

after solving my previous Problems i tried to install several times without
success because the SCSI-Controller performed Bus-Resets all the time. So I
played arround and found out that both Harddisks seemed to be kind of defective
(have to test them in a pc). After installing an other Harddisk the installation
went fine but for some reason this new Harddisk is not bootable (Palo was
executed successfully), its not in the list of bootable devices at startup and
if i select it manualy it fails to boot. But after booting from network the disk
is detected. Since this harddisk was in a PC before I wonder if theres anything
I may have forgotten...

Perhaps. To add/remove jumpers on the HD to enable "Auto-Spinup"?
You need a spec sheet for the HD to figure out which jumpers those are.
If you only have 1 or 2 HDs, it's better to disable "Spinup Delay".

PC BIOS (or scsi controller Expansion ROM) and Linux SCSI drivers 
are smart enough to send a "Start Unit" cmd to spin up the disk.
PDC on most (all?) parisc workstations is not. I don't think the
servers are any smarter but don't know for sure.

sorry - forgot about TI Sync jumper - you want that disabled
for workstations...I think servers are ok with having enabled (no jumper).

"Target Initiated Synchronous Negotiations" is when the Target device
(eg drive) realizes it doesn't have an agreement with the Initiator
(eg host controller) about how fast to send "synchronous" data (SDTR).
Even though the SCSI protocol allows this, older products didn't
do this and the PDC didn't need to (and can't) handle it.

Thanks! My System now boots perfectly from HD and Network.
The only disturbing thing is that the new HD is making terrible noise =
:)
