1 1.3 msaitoh Some Amigas are incapable of booting from partition utilizing a bootblock. One 2 1.1 mhitch example is the PPS Zeus accelerator. The Zeus has two major problems with 3 1.1 mhitch booting from a bootblock. The first (and fatal) one is the driver is just 4 1.1 mhitch plain buggy and will not work. The second problem (if the first problem 5 1.1 mhitch didn't exist) is that the Zeus memory is normally configured during the 6 1.1 mhitch execution of S:Startup-Sequence using a supplied utility program. Even if 7 1.2 snj the Zeus would boot from a bootblock, its memory would not get configured. 8 1.1 mhitch Another example I've run into is the GVP GForce-40. It will boot from a 9 1.1 mhitch bootblock, but it appears to only work if there is a filesystem in the RDB 10 1.1 mhitch blocks for the bootable partition. I've gotten the GForce-40 to boot directly 11 1.1 mhitch from the bootblock by installing the BFFSFastFileSystem in the RDB. 12 1.1 mhitch 13 1.1 mhitch When I was developing the two-stage boot for NetBSD, I wrote runbootblock. 14 1.1 mhitch Runbootblock will load and execute an Amiga bootblock program from a disk partition, 15 1.1 mhitch similar to the process the Amiga ROM will do when booting from the bootblock. 16 1.1 mhitch This allows "booting" from a NetBSD bootblock when the Amiga is unable to actually 17 1.1 mhitch boot from a bootblock. 18 1.1 mhitch 19 1.1 mhitch runbootblock [-d PPSscsi2.device] [-u 1] [-p root] 20 1.1 mhitch 21 1.1 mhitch -d scsi.device Select device driver name, default PPSSscsi2.device. 22 1.1 mhitch -u unit Select SCSI device unit, default 1. 23 1.1 mhitch -p partition Select partition name, default is root partition. 24 1.1 mhitch 25 1.1 mhitch The following command will load and execute the bootblock on SCSI drive 26 1.1 mhitch 2 from the partition named "swap" (which contains the miniroot filesystem 27 1.1 mhitch for installing/upgrading NetBSD) on my Zeus. 28 1.1 mhitch 29 1.1 mhitch runbootblock -u 2 -p swap 30
