Here is what I did for netbsd and when I installed 386bsd You need to get a program called pfdisk.exe It is a simply little partition editor and works quite well. decide how you want to lay out your partition tatble netbsd likes for partitions to be on cylinder boundaries also all to calcuations should be in 512byte blocks. On your system 1 cyl = 17 sec/track * 8 tracks/cyl = 136 blocks 136 * 512 = 69632 bytes. 1024 *1024 * 10 = 10485760 bytes on first partition. divide that by 512 to get number of blocks. 20480 blocks pfdisk will ask for # of cyl for each for each partition. for your first partition you would use 147 cyl even though it doesn't divide out evenly you round down. Use the remaining cyl for the netbsd partition. be sure to use type 165 for that partition. write down all the offset and other partition info. better yet screen print it. The NetBSD installation program should be able to currectly setup the rest. You'll need some kind of boot manager progrm to select which os you want to boot from. I use os-bs132.exe there is a os-bs134.exe also. -- ********************************************************************* * Scott Mace internet: smace@nyx.cs.du.edu * * emace@tenet.edu * *********************************************************************
