I may be wrong, but should'nt the transfert size be ajusted by the ??sdminphys
functions ? If so it should be easy to limit the transfert size to 8k.
I have some time, and a 5000/200 and a 2100 decstation. I could do the
job (i already looked at this), byut i will need some help with the
adapters drivers, as i don't have any knowledge or docs about dec hardware.
Could someone mail me the reasons to not use the MI scsi code now ?
