Jordan, Regarding: =>when I go to commit the changes to disk, I immediately get the following error =>message (as seen on the debug screen): =>vm_bounce_alloc: b_bufsize(0x200) < b_bcount(0x1ff0a400) !! = =Can you tell me if this ever got resolved? I'm alarmed somewhat at =your 2 year tale of woe! Thank you for not letting this fall through the cracks - since I hadn't heard back anything after the intial couple of immediate replies, I was afraid my problem was long forgotten... But no - my vm_bounce_alloc panic problem during install never was resolved, and I still haven't been able to install FreeBSD at all. Back in November, I received the following email from Bruce Evans, giving a clue to where the problem might lie: >This might be caused by a negative block number somehow being passed to >dscheck(). If this happens, then "truncating" the i/o would actually >expand the i/o to the size of the partition plus the absolute value of >the negative block number. Do you have a (BSD) partition of size >approximately 0x1ff0a400 bytes (500+ MB)? Negative block numbers are >used by the file system code but are not supposed to reach device drivers. And my answer was yes - my partition size *is* just over 500MB. The location of the partition, which might be significant, is at the end of a 4GB disk. If I recall, however, I believe the end of the partition was just _under_ the 4GB boundary. Yes, indeed it has been frustrating that during the past two years, on two different PCs, I was never able to successfully install FreeBSD. And this was even _after_ I had bought the hardware to assemble my new PC *specifically* to be compatible with what FreeBSD supported! I'm looking forward to trying out all the great stuff the FreeBSD community has written and/or ported to the FreeBSD platform - once I can get it installed!! :-) So if someone out there can help me over this "hump", I'd really appreciate it... Oh - I just received a phone call from John Dyson, who said he would try to look into (if he has the time). Any and all help appreciated, since (catch-22) I can't look into the problem myself until I get the system installed... Thanks, Gary gtc@aloft.att.com
