IIRC I read about the firmware dropping the high bits of the block address so at some point in time the writes against the disk would "wrap around" and trash the first 4GBs... but it seems its quite an urban legend :) No. That is correct. And it's 1G, not 4G. SCSI commands comes in some different flavors. Old VAXstations (and some others) used 6 byte SCSI commands, which limited the block numbers to 20 bits (some say 21, but I think it is 20). Later systems use 10 byte SCSI commands, which allows for 32 bit block numbers. What happens is that if you go above 20 bits in the SCSI commands of those old VAXen, they will just use the low 20 bits of the block number, so you will indeed wrap. See http://labs.hoffmanlabs.com/node/218 if you want a few more details.

I think it's even only specific 3100 models. And the problem is just that the boot rom uses a more restricted disk block addressing, limiting the booting to disks of less than 1G. (Actually, you can boot from larger disks as well, as long as the boot rom don't need to read from anything above 1G.) Once the OS starts, it uses its own device driver, and then you don't have the restriction either.

I keep reading about people cracking open those chips, and I always wonder why they bother. They're neither expensive nor difficult to find brand-new. Why would one find it worth the time to spend an afternoon performing surgery on that chip to replace the battery when you can get a new one on the way for about eight bucks? I thought the situation was that NOS chips were available, not new ones?
