Help! (bet you never hear that... :-) I tried installing FreeBSD 2.0.5 (release, update, AND 6/22/95 SNAP versions) and keep getting a kernel panic during the installation. It happens as soon as I try to "commit" the settings to the hard disk. The dialog message is (approx.): "Writing partition information to sd0", when I get: "panic: vm_bounce_alloc". My system configuration is: EISA/PCI AMI Titan II motherboard, 90MHz Pentium (single) BT946C PCI SCSI controller 32MB RAM Micropolis 3243 4GB SCSI-2 hard disk Since I *do* have other OSes on my hard drive, I need to keep "DOS translation" mode turned on in the SCSI controller (side note: the 2.0 CD that I bought is useless because of this, but it seems that 2.0.5 *finally* understands the "other" SCSI mapping mode for disks greater than 1GB, right?). I have specified FreeBSD as the third partition, with a 500MB DOS partition as the first partition, and I specified "DOS partition" as the installation medium. So, my questions are: 1. Is this a known problem, that just "doesn't work" in this version? Or is there possibly some installation option that I can change to bypass this bug? 2. Why does the system appear to want "bounce buffers" when I have a PCI bus-mastering SCSI card? Shouldn't greater than 16MB be irrelevant in this setup? (note: I *can't* try running with 16MB of memory, as the Pentium requires 64-bit wide memory, and I only have two 16MB 32-bit[plus parity] SIMMs). 3. Do you think this may be fixed before version 2.1, and/or when do you think version 2.1 will be available? 4. Am I correct that the SCSI disk access routines have been fixed in 2.0.5 to understand the greater than 1GB DOS translation parameters (255 heads, 63 sectors/track) ? Thanks for your time, Gary Corcoran gtc@aloft.att.com
