It is now available as a bundle of 2 drivers:
- ncr53c8xx generic driver that supports all the SYM53C8XX family including
- the ealiest 810 rev. 1, the latest 896 (2 channel LVD SCSI controller) and
+ the earliest 810 rev. 1, the latest 896 (2 channel LVD SCSI controller) and
the new 895A (1 channel LVD SCSI controller).
- sym53c8xx enhanced driver (a.k.a. 896 drivers) that drops support of oldest
- chips in order to gain advantage of new features, as LOAD/STORE intructions

available since the 810A and hardware phase mismatch available with the

SCRIPTS (avoids the phase mismatch interrupt that stops the SCSI processor
until the C code has saved the context of the transfer).
Implementing this without using LOAD/STORE instructions would be painfull

The 896 chip supports 64 bit PCI transactions and addressing, while the
895A supports 32 bit PCI transactions and 64 bit addressing.
A boot setup command for the ncr53c8xx (sym53c8xx) driver begins with the
driver name "ncr53c8xx="(sym53c8xx). The kernel syntax parser then expects
-an optionnal list of integers separated with comma followed by an optional
-list of comma-separated strings. Example of boot setup command under lilo

Some scsi boards use a 875 (ultra wide) and only supply narrow connectors.
If you have connected a wide device with a 50 pins to 68 pins cable
converter, any accepted wide negotiation will break further data transfers.
- In such a case, using "wide:0" in the bootup command will be helpfull.
