Hi

Since one of the only things that changed between 2003-03-09 and
2003-03-10 is boot1a.S is it possible that it is the problem?  

I have found that commenting out the following code in
arch/i386/prefix/boot1a.s

main.5:		mov %dx,MEM_ARG			# Save args
		xorb %dh,%dh			# 0 means use blockcount
		mov $0x7e00,%bx
		callw nreadbx			# Read disk
		push %si
		mov $msg_r1,%si
		callw putstr
		pop %si
-		ljmp $0x800,$0			# enter the rom code
+#		ljmp $0x800,$0			# enter the rom code

Shows the following:

.0000.0024 done
.0001.0000.0000Rd err

Obviously it is not jumping to the rom location.  But if I do the
following:

-		ljmp $0x800,$0			# enter the rom code
+		ljmp $0x800,$6			# enter the rom code

It still does not work but it does not reboot.  I am way over my head in
assembly.  Is it possible tha the rom is not in the expected location?

I can however send a floppy image to you to test to see if the code that
is being generated on my end works.

My upgrade to Slackware 9 did not resolve the issue.
