I have an old emulex SCSI to ESDI controller connected to a WREN III. I have the file system mounted and operational. The only problem seems to be booting. I have to boot using SCSI PROBE from the control panel. The boot sequence results in one of two things: a) Driver set to do blind reads, systems crashes sometimes with crazy video sometimes with sad mac 0003. b) Driver set to do regular reads, System hangs with happy mac icon on screen. Any one got any ideas? Thanks in advance - Mike

The software driver is Silver Lining 5.17, on a Mac SE 6.0.4. This config has been working fine for 18 months. Now, this same drive will not work properly with a Mac Plus and it has something to do with the way the SCSI chip polls the device and requires booting from a floppy before the drive will be recognised. I hope this has been some help, if I can be of some more help mail me. PS. Mike I tried to mail you direct but I got a mail message User Unknown, our software people think its a problem on your end. You may wish to check it out. Regards. -m------- George Budahazy - Victoria Engineering Manager glb@yarra.oz ---mmm----- Pyramid Technology Corporation Pty.
