I've retired perfectly good systems that can't handle having a 600MB disk connected to them. Anything over 540MB seems to give it fits, although I suppose that a BIOS upgrade would help. I couldn't even lie to the BIOS and tell it that the drive's geometry was such that only 540MB would be used.

I can't see why else you would want to take a perfectly good 8GB+ disk and use it as a 2GB drive. The volumes probably mean it's not cost-effective to either continue to produce smaller older technology drives, or design a new small drive. Of course, some of them may not even tolerate that much space. AFAIK, the BIOS in my Toshiba T1850 won't allow anything bigger than 130MB. Getting FreeBSD into my current 80MB isn't fun (and the major reason it hasn't been updated from 2.2.5 - I can't cut 3.x down far enough to fit, and -current is even larger).

Re: -pipe switch in kernel compilation
Before you ask, I've also tried to use the tapr[*] CF - IDE adapter to see if I could get these systems to boot off a 16MB CF card with no luck. I even have a mini486 based system from NEC that I bought surplus that I thought could use the CF card, but no joy. Works great on all the modern machines I've tried it on. likely a BIOS issue, but I don't wanna write bios for a machine that only cost me $49.99 that has no docs.
