I'm having a little trouble, and maybe someone can help. The configuration that works is: AMI Mark-II 386-33 motherboard, with 8MB RAM on motherboard (reported as 8064K by both the BIOS and boot messages) SCO Unix 386 Release 3.2v2.0 (no SLS's added to system) A little while ago, I added 4MB RAM to the system using the add-on memory board that works with the motherboard. The new RAM was recognized by the BIOS during system start-up, and the total matched what the manual said should have been reported (11904K). BUT, when I got to the Boot: prompt, the hd(40)unix message would appear, and then the system would reset and begin the boot cycle all over again. If I type "dos" at the Boot: prompt, DOS would come up OK. Is there any reason SCO Unix should not be booting when going from 8064K to 11904K? I'll run a more thorough RAM test tomorrow, but my guess is that the RAM is OK. But, I wouldn't expect SCO Unix to flake out either. HELP!!!!! ------------- James B.

I had this same problem when I went over 16 meg. I called SCO and discovered that during the boot process they REALLY check the memory over, and if any problems are found the system dies. For a fix I called AMI and they sent a new version of a PAL that fixed the problem altogether. This PAL was free and they shipped it overnight. Make sure that you have none of the BIOS ram shadowing enabled, and check your sims to make sure that they are all rated at 80ns or faster. -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | Mark Hilliard, N2HHR | AWK is not just a | | Fax 315-986-5882 | LANGUAGE | | mark@gizzmo.kodak.com | It is a way of LIFE! |
