Hi fellow netters ! I asked for help with my problem that ISC 2.2 won't boot on my 33 Mhz 386 system which had a AHA-1542B SCSI controller. Thank you for all the mail I received. I tried everything suggested (and even more) but I can't get it to work. However, I think I know the real source of the problem. I put the AHA-1542B and the disk (Micropolis 330 MB) into another 386 system (Motherboard is from the same company but runs with 25 Mhz instead of 33 Mhz in the original system). Now, guess what happens, it boots and I could install the core system on it. As my dealer suggested I put the controller and the disk back into the other system (33 Mhz) and tried whether it would boot from the harddisk. It didn't. So, I tried the 33 Mhz computer with an ESDI disk and the WD-1007 (?) ESDI controller. ISC 2.2 didn't boot with this, too. I exchanged the BIOS between the two systems (both have AMI BIOS and the C&T chipset) but nothing did change, i.e. the system still didn't boot ! Now, I will blame the motherboard (or its configuration). I will compare the configuration (a few jumpers and the C&T chipset) and I will report whether I had some success or not. So, for now, be careful with the 33 Mhz AGC motherboard and ISC 2.2. It works perfectly with the 25 Mhz AGC motherboard (cache version), though ! Thank you all for your help, especially with the hint, that no disk should be entered into the CMOS-RAM if there is a SCSI disk in your system. I hope to report some success later, Norbert Bladt. -- Norbert Bladt, Ascom Autelca AG, Worbstr. 201, CH-3073 Guemligen, Switzerland Phone: +41 31 52 92 14 Mail: nbladt@autelca.ascom.ch UUCP: ..!uunet!mcsun!chx400!hslrswi!aut!nbladt

It's only an idea, but our ISC didn't run the install program properly because we had a VIDEO-CARD with a TSENG-4000 installed, something in the install program doesn't like the tseng-chip. This is expressed by mostly destroying the install-disk (which must be writable!). The solution is to replace the TSENG-4000-SVGA by a normal vga or ega or Hercules card. Then install the ISC and change to the SVGA as ISC itself has no problem with the TSENG-chip. As I encountered this problem, I blamed the motherboard first, too. But it really was the VGA! So if you have a SVGA you should try to change the video equipment as well! prefect A.Wallaschek Adrian.Wallaschek@ARBI.Informatik.Uni-Oldenburg.DE
