; ; FIX FOR NULU VERSION 1.5 ; A Message from Martin Murray ; with acknowledgements to ; Howard Goldstein ; 01/09/86 ; ; A fix has been found for NULU v1.5. Like all good fixes, however, it ; causes its own share of problems and can only stand as a temporary fix ; until I can get version 1.6 out. The problem was BDOS function 37, ; which NULU15 uses before writing to a drive in case it has been ; changed. Under certain circumstances, BDOS loses its mind when this ; function is called and starts giving away previously allocated disk ; blocks. This is no good for anyone. The "solution" lies in NOT USING ; BDOS 37. The problem now is that you cannot tell NULU to log in a new ; disk. Oh well, try to live with it until I get the new one out that ; will support the fix. ; ; Assemble with your favorite assembler and merge the resulting .HEX ; file into NULU15 with MLOAD. ; ; MLOAD NULU151.COM=NULU15.COM,NULUFIX.HEX ; ; The result will be NULU 1.51 and will have the date of 01/09/86. ; ; More than special thanks are due to Howard Goldstein for this fix. He ; found the problem. He tested the fix. He waded through all my self- ; modifying code. His family will appreciate any help in paying the ; psychiatrist's bills. ; ; ORG 010CH DB '1' ; ORG 0110H DB '01/09/86' ; ORG 0150H DW 9832H ; ORG 32B9H RET ; ORG 32BCH RET ; END
