Installing a fresh 40 gig Hard Drive in a Toshiba Libretto 100CT for Dual Booting Windows 98 SE and IBM PC DOS 7.0
I recently installed a brand new Fujitsu 40 gig HD (model MHT2040AT - 9.5mm, 2.5", 4200 RPM) into my Libretto 100CT. The drive cost me $70.
The problem with installing hard drives in the Libretto 100CT that are bigger than 8 gb is that the Libretto 100CT's BIOS has a hibernate "sleep" routine that writes the contents of memory to the hard drive. The 100CT BIOS writes directly to the 8 gig position of the hard drive as it assumes that the hard drive ends there. The Libretto 100CT thinks that all hard drives are not larger than 8 gb. This means that any data that is there is overwritten! To prevent data loss you have to create a small 100mb partition that you never use and thus it becomes reserved for the Libretto's hibernate function.
Here's how I did it.
Tools needed:
1. Partition Manager 8.0 floppy disks
2. EZ Bios software
3. Windows 98SE Boot floppy
4. Floppy Drive for Libretto 100CT
5. AC adapter for Libretto 100CT
6. Desktop computer with BIOS that will see entire 40 gig hard drive space of the hard drive.
7. 2.5" to 40 pin IDE cable adapter
8. Dual boot software
I first updated the Toshiba Libretto 100CT to the latest BIOS 6.50. See the Toshiba website for the BIOS & info on how to flash it. Make sure you are using an AC adapter when doing any BIOS updates or hard drive partitioning!
I used Partition Manager 8.0 to do the partitioning.
1.. Step 1. Install the hard drive. Any 2.5" 9.5mm high hard drive will fit.
2.. Step 2. Boot the Libby from the Partition Manager Floppy Boot Disk 1, then insert Disk 2 and get PM8 up and running. Use an AC adapter and an external mouse!
3.. Step 3. PM8 will see the disk as an 8 gig disk. Contrary to published reports, PM8 does in fact use the BIOS info to size a disk. It does NOT read the hard drive directly. Since I dual boot to DOS and Win98, I first created a 2 GIG FAT PRIMARY partition for DOS. I then created a PRIMARY FAT32 with the rest of the "8 gig" drive for Windows 98. Since PM8 uses the Libby BIOS to size the disk, the hibernation area of the hard drive is properly reserved. Write down the beginning and ending sectors for each partition using PM8 INFO menu option. If you don't want a DOS partition, simply create a single FAT32 partition.
4.. Step 4. Remove the hard drive from the Libby. Install it in your desktop computer to complete the partitioning. Use a desktop that the BIOS can see past the 8 gig barrier! Make sure your PC BIOS sees the hard drive when it boots! You may have to jumper the 2.5" hard drive as a slave.
5.. Step 5. Boot your desktop with the PM8 floppies. PM8 will now see the entire size of the hard drive (in my case 40 gigs). You should see two primary partitions and a bunch of unallocated space. I created a 3rd primary partition with two partitions in it.
6.. Step 6. In the 3rd partition, first create a 100mb partition. This will become the area that the Libby uses when it hibernates. The Libby will copy the contents of memory to this area. Do NOT format this partition! Now create the last partition using all the remaining hard drive space (in my case it was about 29 gb). Format it as FAT32. While I had the hard drive in my desktop I copied the WINDOWS 98 install files (the WIN98 directory from the Windows 98 CD) to the 6 gb FAT32 partition (and the Toshiba Windows 98 files) and the DOS install files & my DOS utilities to the 2 gb FAT partition. This makes getting the OS installed much easier!
7.. Step 7. Put the hard drive back into the Libby. Install EZ BIOS. Re boot using the Windows 98 Boot disk, navigate to the WIN98 directory, type SETUP and Windows 98 will start to install. You will need to get the Windows 98 files for the Libretto 100CT from the Toshiba web site.
8.. Here's how my 40 GB Fujitsu drive ended up being partitioned:
1st PRIMARY partition FAT 2 GB
2,047.3 mb
1st sector: 63
last sector: 4,192,964
2nd PRIMARY partition FAT 32 5.9 gb
1st sector: 4,192,964
Last sector: 16,338,104
3rd PRIMARY partition EXTENDED
1st Partition 101.9 mb NOT FORMATTED
1st sector : 16,338,168
Last sector: 16,546,949
2nd Partition 29.3 GB FAT32
1st sector: 16,547,013
Last sector: 78,140,159
After Windows 98 SE was up and running I installed my Boot Manager (System Commander from V Communications). I then installed PC DOS 7.0.
I believe that this methodology will work with any hard drive up to 127 gb in size. That is where EZ BIOS stops translating sectors as I understand it. Once my 40 gig drive fill ups I will install a 100 gb!
I hope that this info was helpful!
