[ lengthy discussion on ISC 2.2 install disk hang problem, possible causes and various attempted resolutions deleted for the sake of brevity ..... ] Today I spoke with an engineer with Transcomputer who has *solved* the mysterious ISC 2.2 install disk hang problem. Evidently the new 2.2 release enables instruction pipelining in the 386 processor, something which ISC neglected to tell us poor souls. Check your 386 processor, just below the i386 logo should be the processor version. If the chip is the SX211 version, you're in trouble because there is a bug in processor regarding instruction pipelining (don't confuse SX211 with the 386SX chip! we're talking about the processor revision number here!). The solution is to replace the chip with the "SX219" version, the hang problem will vanish completely. I indeed checked my processor and I have the faulty 386 chip. intel i386 A80386DX-33 IV SX211 <== There it is! L9310437 INTEL (m)(c) '85 I advise everyone to check their processor version before upgrading or purchasing 2.2, this problem will most likely affect *any* machine with the SX211 version chip. -- Arthur W.
