Well, I've gone and done it...I have upgraded my 2000 by adding the 1.3 autoboot ROM and changing from my A2090/ST251-0 (ST-506 type) combo to the GVP 80-meg hard card...Autobooting is so nice!! Disk performance figures (according to Dperf2) have gone from AmigaFF: (40 meg FFS partition on ST251 drive) Create Files: 6 files/sec. Directory Scan: 89 entries/sec. Delete Files: 40 files/sec. Seek/Read Test: 101 seek/sec. Read/Write Speed Test: (bytes/sec.)

The install software was very easy to follow (I decided to answer "NO" to default install parameters (2 40 meg partitions) thinking that wouldn't let me autoboot. Well to my surprise, it made all three partitons FFS and it DID autoboot...a check of the Mountlist showed what GVP does to allow all partitions to be FFS *AND* be auto-bootable. Nice! So with that learned, I went back and re-did the install (it checks to see if you've already done it and then "undoes" it), this time selecting the default configuration. It formatted very fast. (BTW, if you want one *BIG* 80-meg FFS disk, no problem...reply "NO" to default configuration question and enter the full disk size to the "How big do you want partition 1?" question...The GVP book needs to be updated on this, it still assumes you want to create a boot disk) All the above may be old hat to some people, but I felt it was worth mentioning for those who are thinking of getting a GVP hardcard. This brings me to my questions... 1) The install-created mountlist gave me a 2-sided drive with 32 sectors per track and 1281 cylinders per logical drive. Should I change the mountlist and reformat or (since it is a SCSI drive) should I leave well-enough alone?? The Mountlist for the drives created (DH0: and DH1:) are as follows: DH0: Device = scsidev.device Unit = 1 /* For HD with SCSI ID = 0, Capacity: 80.11MB */ Flags = 0 Reserved = 2 Buffers = 32 BufmemType = 4 Surfaces = 2 BlocksPerTrack = 32 LowCyl = 1 ; HighCyl = 1282 /* Partition 1, Size 40.06MB */ GlobVec = -1 /* Required for FFS */ StackSize = 4000 /* Required for FFS */ DosType = 0x444F5301 /* Required for FFS */ FileSystem = L:fastfilesystem /* Required for FFS */ MaxTransfer = 77abcdef /* (for Patch2090) */ # DH1: Device = scsidev.device Unit = 1 /* For HD with SCSI ID = 0, Capacity: 80.11MB */ Flags = 0 Reserved = 2 Buffers = 32 BufmemType = 4 Surfaces = 2 BlocksPerTrack = 32 LowCyl = 1283 ; HighCyl = 2562 /* Partition 2, Size 40.00MB */ GlobVec = -1 /* Required for FFS */ StackSize = 4000 /* Required for FFS */ DosType = 0x444F5301 /* Required for FFS */ FileSystem = L:fastfilesystem /* Required for FFS */ MaxTransfer = 77abcdef # 2) With the hard card in place, I find I can no longer boot from a floppy (either from power-up or three-finger salute)...the hard disk kicks in every time. Any suggestion?? Thanks to anyone who cared to read my $.02 worth.
