Titolo: Un pò su 2940

- Il controller č marcato 2940 senza sigle, che tipo č? : U, UW o altro o
solo 2940
- A che specifica devo far riferimento per cercare periferiche ? ( Wide Ulta
fast ecc.)
- Lo stesso č installato sull ID 7 e corretto?
- Ho installato una periferica (l' unica) dss (backup a nastro)  viene
riconosciuta su ID6,
   puo andar bene? (non posso testarla non   ho i drive per win)
- Ho cercato di installare due dischi e un cdrom (vetusti hd 100 mb, lettore
2x)
   non sono stati riconosciuti
- Devo terminare qualche cosa?
- Ho dimenticato qualche cosa?
- Il bios riporta sulla schermata di boot:  " ver. 1.16 ",  devo/posso
aggiornare?
- Puň essere ancora un controller valido per normali operazioni
(scannerizzare, masterizzare)?
- Il cavo ha quattro connessioni, posso sostituirlo con uno a 7 connessioni
se servisse?
- Aggiungendo periferiche esterne (al connettore esterno 50 pin piccoli )
devo compiere
  qualche operazione particolare?
- Vorrei aggiungere un hd,  qualche giga  3/4 anche usato, quale per questo
controller?
- Altre eventuali operazioni da fare?
- se ho fatto domande  poco pertinenti non rispondere capirň:-)

Ammazza... direbbero a Roma, quante domande !!!
Il tuo controller 2940 se ha due connettori interni (uno da 50
pin ed uno da 68 pin) più un connettore esterno da 68 pin è un
2940uw; altrimenti è "solo" un 2940u. Tutte le periferiche wide
richiedono 68 pin (le SCA 80 pin) tutte le altre 50 pin, gli
scanner ed alcuni zip drive 25 pin.
Si, il controller si installa come Id 7
Si, anche per l'unità a nastro
Per le periferiche vetuste, ti consiglio di provarle una per
volta e singolarmente sulla catena scsi, perche possono essere
incompatibili con l'host o fra di loro. Potresti trovare che
tutte da sole funzionano ma in catena no. Poi c'è il problema dei
driver per win. Per gli hd da 100mb penso siano troppo lenti
anche se funzionanti per le attuali richieste.
Devi terminare solo l'ultima periferica della catena scsi; es.
host---hd--hd--cd--mast(term); assumendo che l'host si termina da
solo; se sulle periferiche che monti non c'è la possibilità di
attivare la terminazione interna devi procurarti una terminazione
da inserire dopo l'ultima periferica sul cavo piatto
Se funziona non aggiornare nulla, fallo solo quando è necessario
per malfunzionamenti/incompatibilità. Inoltre non tutti i
controller hanno una flash eprom che permette una
riprogrammazione lampo, alcuni possono essere riprogrammati solo
con alcune attrezzature specifiche, dai uno sguardo al sito
adaptec.
Si penso che sia ancora una controller utile per masterizzare e
scannerizzare, forse meno per gli hd se non è wide.
Si il cavo può avere fino a 7 connettori
Per la catena esterna devi trovare informazioni per sapere se il
tuo controller può gestire contemporaneamente sia la catena
interna che quella esterna, poi devi assicurarti di aver
terminato tutto una sola volta, es. scanner(term)-- host (non
term) -- hd-- hd-- cd(term); inoltre devi rispettare le lunghezze
dei cavi per non generare interferenze sulle linee e terminare lo
scanner con una term attiva se possibile
Controlla se il tuo controller ha il bios per il boot, prova con
ctrl-a alla partenza e leggi le varie opzioni se disponibili
buon lavoro

-----------------------------------------------------------------
OVERVIEW
The AHA-2940 host adapter brings the highest performance SCSI I/O
technology to the fast PCI local-bus. Based on Adaptec-designed
RISC technology, the AHA-2940 maximizes system I/O performance
and utilizes the PCI local-bus to transfer data up to 133
MB/second. This series of high-performance, intelligent host
adapters supports advanced SCSI features and bus master direct
memory access (DMA) data transfers. Combined with the high
performance of SCSI and the fastest system bus available, the
AHA-2940 delivers maximum I/O throughput for demanding desktop
and network server applications.
The AHA-2940 PCI host adapter brings compatibility, reliability
and ease-of-use to the desktop or server PC. The AHA-2940 is
compatible with all major operating systems, SCSI-1 and Fast
SCSI-2 peripherals, as well as industry-standard application
software. Adaptec's extensive testing program ensures
compatibility between the PCI system and the SCSI host adapter.
The AHA-2940 features the BIOS-resident SCSISelect configuration
utility which eliminates the need to handle jumpers or
terminators while installing the board or adding peripherals. All
configuration and terminator settings are controlled via the
keyboard. This means that once the host adapter is installed, the
PC chassis need never be opened again.
-----------------------------------------------------------------
KEY BENEFITS
RISC-based SCSI - the key to maximum performance
The AHA-2940 is the newest addition to the Adaptec line of
RISC-based SCSI host adapters. At the core of this new host
adapter family is the Adaptec-designed PhaseEngine RISC
processor. The 10 MIPS PhaseEngine processor minimizes the time
it takes to process SCSI commands by automating SCSI phase
changes and advanced SCSI features. This allows the CPU to
perform other tasks and improves overall system efficiency and
performance.
The programmable PhaseEngine RISC processor also executes
self-contained microcode, which is downloaded by the main CPU at
system initialization. This enables quick and easy microcode
upgrades. Further, a 64-byte scratch memory stores configuration
information established by the BIOS-resident SCSISelect
configuration utility.
With the Adaptec-designed RISC processor, the AHA-2940 host
adapter maximizes system I/O performance by utilizing the PCI
local-bus to process data at transfer rates of up to 133
Mbytes/second. This new technology is essential in meeting the
demands of high-performance applications.
Wide SCSI support for increased performance
The AHA-2940W PCI-to-Wide SCSI host adapter provides connectivity
to 16-bit as well as standard 8-bit SCSI devices. This
connectivity increases I/O performance by doubling the maximum
SCSI bus band-width from 10 Mbytes per second for standard 8-bit
SCSI to 20 Mbytes per second for Wide 16-bit SCSI.
Simple installation and easy, flexible configuration
The AHA-2940 family of host adapters is easily installed and
configured. Simply install the board in the PCI slot, then run
the menu-driven SCSISelect configuration utility resident on the
host adapter. The SCSISelect configuration utility eliminates the
need to handle jumpers, making host adapter installation quick
and easy. In addition, the programmable active termination
featured in the AHA-2940 family and con-trolled by the SCSISelect
utility makes installation of external SCSI peripherals fast and
simple.
When upgrading the PCI system with external SCSI peripherals,
there is no need to open the PC chassis. Adaptec's SCSISelect
utility provides key information on-screen, including the host
adapter version and current configuration. Active termination and
other host adapter settings may then be reconfigured on-screen
through menus rather than handling jumpers and changing switch
settings on the hardware.
Proven Adaptec quality and reliability
The hardware for the AHA-2940 family of host adapters is based on
state-of-the-art VLSI technology, providing maximum performance
and reliability. To ensure compatibility with PCI systems, the
AHA-2940 family has undergone exhaustive testing in Adaptec's
compatibility test lab. In addition, each board is subjected to
extensive functional and mechanical inspections and tests to
ensure the highest quality and reliability.
As the PCI standard becomes established in the industry, Adaptec
recognizes the need to work with core technology providers to
ensure long-term compatibility. Adaptec has been proactive in
building relationships with leading BIOS, core chip-set and
system providers to assure compliance and compatibility with the
PCI 2.0 specification. Our on-going testing and reporting
procedures allow us to provide users with the most current PCI
compatibility data.
In support of its commitment to quality, Adaptec's manufacturing
facility has earned ISO-9002 certification. This international
quality standard, established by the International Organization
for Standardization (ISO), ensures a high level of product
quality, production, testing and service.
