See following section 3.10 from the readme in the IBM docs with current OS2DASD.DMD: Notice also the zero-based DISK numbering scheme used as parameters to os2dasd.dmd, and occasionally used internally in LVM.(critically read output from "lvm /startlog:") 3.10 Very Large (512 Gb limit) Hard Drive Considerations ________________________________________________________ The previous version of OS2DASD.DMD had a 512 Gb geometry limitation which allowed only part (remainder of the total drive capacity divided by the 512 Gb) of the hard drive to be accessible for the system. The current version of OS2DASD.DMD removes this limit and allows total capacity of the hard drive up to 2 Tb. This support has the following options: 1. If the drive is used as a boot drive, only first 512 Gb of the drive space will be accessable to the system. 2. If drive is used only as a data storage drive the total capacity (up to 2 Tb) of drive will be accessable to the system. The two new parameters are available to select these options: o /BOOTABLE --- applied to the unpartitioned large drive (during the bootup prior to the first partitioning of the drive) and makes drive bootable, but limiting its available capacity to 512 Gb. o /FULLSIZE --- applied to the unpartitioned large drive (during the bootup prior to the first partitioning of the drive) and allow use of the total capacity of the drive (up to 2 Tb), but prevents the drive from being made bootable. The parameters have the following usage syntax: BASEDEV=OS2DASD.DMD [/D:n] [/BOOTABLE | /FULLSIZE] where /D:n denotes the number of the drive (/D:0 is drive 0, etc.). Parameter /BOOTABLE or /FULLSIZE following /D:n is applied to drive n. If for some drive value n (n>0) the /D:n parameter is omitted the following parameter (/BOOTABLE or /FULLSIZE) is applied to the first drive (default /D:0). If parameter /BOOTABLE or /FULLSIZE for some drive is omitted, /FULLSIZE is applied for this drive by default. If drive is larger than 512 Gb, then LVMUPDT package must be installed in addition to the IDEDASD package to access the full drive capacity (/FULLSIZE option). If drive is not larger than 512 Gb that IDEDASD package is enough to access the full drive capacity, but LVMUPDT package may be installed in addition. regards, Mike ---------------------------------------------------------------------------------- **= Email 3 ==========================** Date: Tue, 09 Dec 2008 01:27:38 +1100 (EDT) From: "Ian Manners" Subject: Re: large drives and long JFS format Hi Mike, >Actually Boot disk size can exceed 512GB, but only the first 512GB of a >Bootable disk will be usable.

It allowed me to LVM and format a 1Tb drive lastnight, I xcopied OS/2 across, (didnt use any switches), disconnected both my normal SATA disks and booted ok to the 1Tb disk, strange, didnt have to set the drive bootable in LVM, had a CD handy thinking I was going to have to. Ran pmmail and seamonkey ok. Left the computer up overnight and this morning when I turned the monitor on the mouse pointer worked but nothing else did. Rebooted and started using the PC with Seamonkey, PMMail, opened OpenOffice and splat, died with only the mouse pointer working. rebooted again and the boot is stuck around the VirtualPC driver. a few reboots and PC freezes about same spot with HD light on full each time. Reconnected my main to HD's and here I am. I suspect if I zap the partitions and run with the /BOOTABLE switch, clean partition, and have the 1Tb drive as primary then I will only see 512Gb of the drive but it will boot fine. I'll try that next time. This is just messing around to see what happens in moments of waiting for other things :-) Cheers Ian Manners http://www.os2site dot com/ ---------------------------------------------------------------------------------- **= Email 8 ==========================** Date: Tue, 9 Dec 2008 10:31:26 +1100 (EST) From: "Voytek Eymont" Subject: Re: Java programming > Hint to anyone buying a Windows machine: insist on getting XP installed.. > XP is a very major improvement over Vista. perhaps if you quadrupled RAM and processor speed, it might be OK?

To check things out I installed the development kit for Java 1.3.0 (which I happened to have on an IBM Software Choice CD), renamed the Java11 and java131 directories (so they were unlikely to be used), removed all references to java11 and SWING_HOME from config.sys, and added C:\java13\jre\bin; to PATH (C:\java13\bin was already there).

(Question: what >does "if (a=b=c)" mean? Answer: it's one of the design flaws that killed will not compile under java, as all conditionals *must* resolve to a boolean. SO, in the above example, you want: if ( (a = b = c) != 0) which is what is implied from the older C constructs. a and b are assigned to the value of c and then tested to see if c is non zero, if it is, then the body of the if statement is executed. >off PL/1, a language that, unlike modern programming languages, followed >the bad Fortran habit of using "=" for assignment instead of comparison. >Second question: what does "x?y:z" mean?
