Subject: Can't install 2.1.5R on an IBM ThinkPad 365X

The 2.1.5R installation diskette won't boot correctly on an IBM ThinkPad
365X.  I understand that this machine has a 100 MHz Pentium, 8 MB of main
memory, an 800 MB internal hard disk (EIDE?), and an Adaptec PCMCIA SCSI
card.  It seems to finish loading the kernel from the installation
diskette and then crashes almost immediately:

	(kernel autoconfiguration monologue)
	        .
	        .
	        .
	rootfs is 1200 Kbyte compiled in MFS
	 
	Fatal trap 12: page fault while in kernel mode
	fault virtual address   = 0x4d4d4d51
	faultcode               = supervisor read, page not present
	instruction pointer     = 0x8: 0xf0130ec1
	code segment            = base 0x0, limit 0xfffff, type 0x1b
	                        = DPL 0, pres 1, def32 1, gran 1
	processor eflags        = interrupt enabled, resume, IOPL=0
	current process         = 0 (swapper)
	interrupt mask          =
	panic: page fault

Can anyone explain the cause and/or suggest a workaround?

Thanks,
