Message-ID: <1989Aug12.011138.5217@tmsoft.uucp> Date: 12 Aug 89 01:11:38 GMT Reply-To: mshiels@tmsoft.UUCP (Michael A. Shiels) Followup-To: comp.sys.ibm.pc Organization: MaS Network Software and Consulting Lines: 12 Serious problem found in the DUAL BOOT option for MS OS/2 1.10 toolkit The boot sector for C: (or what ever) that it creates has a bad assumption coded into it. It assumes AX is 0 when in fact most (all the ones I checked, over 10) hard drive MASTER boot records leave 55AA in AX since they just verified that the sector was a boot sector. Easy to patch in some since you can just xor AX,AX before jumping from the MASTER boot block to the PARTITIONS bootblock.
