 ==== Hard disk ====
-Toshiba T3200SXC came with either a 40 MB hard drive, or an 120 MB hard drive. The system has a standard IDE interface to connect to the supplied Conner CP hard disk. Most Toshiba T3200SX(C) computers certain newer BIOS versions are locked to specific hard disk part numbers, so you cannot upgrade it easily. If you try using a different hard disk, the computer will refuse to detect and use the hard disk, unless it has a certain part number starting with the letters "CP" which stands for Conner Peripherals. Older BIOSes will allow you to use any hard drive, but will still use the disk settings for the hard drives that were originally supplied with the system. In this case, you can override the settings programmatically, with Anydrive, found under [[Files and Resources]].

 If you're technically skilled, HighTreason has made a tutorial how to flash the BIOS onto an EEPROM. Flashing a compatible BIOS will allow you to boot with any hard disk. Please see [[Files and Resources]] for more information.
+==== CPU upgrades and overclocking ====
+I've been informed that on the T3200SX it is possible to replace the CPU with a TX486SLC upgrade. The oscillator can be upgraded to 40 MHz giving a 20MHz effective CPU speed.
 ==== RAM memory upgrade ====
-The computer uses 30 pin SIMMs to add more system memory, but it's not completely standard. The computer was shipped with 1 Mb (megabit) or 2Mb memory chips that were 80ns (or faster) with parity. There are six slots in total and the banks are used in pairs, so at least two are needed.((Source: http://baudband.net/?page_id=88))

 The computer can be upgraded with an math coprocessor (FPU). The FPU doesn't come as standard, but the computer has a provision for an added Intel 387 FPU.
+==== AT keyboard connector ====
+The computer has a DIN connector for a AT style keyboard but it may be covered by a plastic cap. Please see the [[DIN keyboard connector]] page for more information.

-**Q: I can't get a larger/custom hard drive working on my T3200SX(C). My computer won't boot, or it will refuse to detect the drive. **\\
+**Q: How do I upgrade the Hard Disk? **\\
-**A:** Unfortunately newer Toshiba T3200SX BIOSes are restricted to specific CONNER hard-drives of either 40 or 80 megabytes (the T3200SXC accepts 40 or 120 MB). On bootup, the BIOS queries the IDE controller for hard-drives, and will prevent the system from booting when it detects a hard drive with a part number that doesn't start with the matching letters 'CP' (Conner Peripherals).
+**A:** It depends on the BIOS version of your Toshiba portable (see below for instructions how to check the BIOS version). Most Toshiba T3200SXC BIOSes are restricted to CONNER hard-drives of either 40 or 120 megabytes size. On boot-up, the BIOS queries the IDE controller for hard-drives, and depending on your BIOS version, one of two things will happen:
-There are three options:
+  - ** Older Toshiba BIOS (such as 003C) **
+    - The computer will detect any drive and just assume it's a 40 MB  disk (regardless of it's actual size).
+  - ** New Toshiba BIOS (such as 003E/003F) **
+    - The computer will only detect a drive manufactured by Conner. It will assume it's a 40 MB drive (regardless of it's actual size). If you have a different drive than Conner, your computer will simply refuse to detect the hard disk. The model/part number of the disk must start with the letters 'CP' (Conner Peripherals) for it to be detected.
+You have a couple of options:
+  - If you have the **older BIOS**, your computer should detect any hard disk, but the computer will assume it's a 40 MB drive and the setting can't be changed. You can still boot from it, but you'll only be able to use up to 40 MB of the disk. To use larger hard disks, you will need to download ANYDRIVE (found in the files section) or any other BIOS HDD overlay program that installs in the MBR of your hard disk, and overlays the correct hard drive parameters at startup. Anydrive overrides the BIOS settings so you can use any size hard disk up to 504 MB. You can even use larger disks, but only 504 MB will be usable, if using Anydrive. If you know of other overlay programs that allow for larger hard disk usage, please let me know.
+  - If you have the **newer BIOS**, you can do the following:
+    - Your Toshiba can boot from a floppy disk, but you will not be able to use the hard disk.
+    - Buy a Conner hard-disk. The important bit is that the the part number starts with the letters 'CP'. Then use ANYDRIVE to circumvent the BIOS hard-coded drive size limitations.
+    - Replace your BIOS chip with an older BIOS, or hunt down a spares -computer with an older BIOS version (such as 003C) and replace the chip.
+  - If you have a PROM programmer, flash a BIOS chip with the 3CH BIOS found in the files-section, and use ANYDRIVE to circumvent any size limitations. There is a well written BIOS re-flashing guide in the files page in the section labeled Documentation.
+Note: If you plan to use a drive other than what is supported by your BIOS, I highly recommend a BIOS HDD overlay software, so that you may avoid data corruption.
+**Q: I upgraded the hard disk on my Toshiba, but now it refuses to boot, or detect the hard disk.**\\
+**A:** If you have verified the replacement disk is fully working, then your computer must be using a BIOS version that only detects and supports Conner hard disks. See above for details.
+**Q: How do I check the BIOS version? **\\
+**A:** You need to open the portable computer. Remove the four screws from the bottom front of the laptop. Open the screen lid. The keyboard should now lift up starting from the front. You may need to pry the keyboard a little. Once the keyboard is off, remove two screws at the rear of the EM shield between the keyboard and the motherboard. Remove the EM shield. You will see three chips. The one at the bottom right corner is the BIOS chip. I've only seen 003C, 003E and 003F out in the wild. If you have a different BIOS version, please take a picture of it and send it over! If you have the capability to read the BIOS chip, I would appreciate a BIOS image. I will gladly host it on this site.
-  - Buy a working CONNER Hard-disk with the part number starting with 'CP', and use ANYDRIVE to circumvent the BIOS hardcoded drive size limitations.
-  - Get an older BIOS chip, or hunt down a spares -computer with an older BIOS version and replace the chip.
-  - Re-flash your BIOS chip with the 3CH BIOS found in the files-section, and again use ANYDRIVE to circumvent any size limitations. There is a well written BIOS re-flashing guide in the files page in the section labeled Documentation.
-On older Toshiba T3200SX machines (BIOS 003C) the computer will boot with any peripheral IDE drive, but you may still need to use ANYDRIVE to circumvent the BIOS hard-disk size limitations, because older BIOSes assume the hard disk is 40 MB. It may boot, but using the computer could cause hard drive corruption. With ANYDRIVE enabled, the program will manually reprogram the BIOS to use whatever size hard disk you want and utilize up to 512 megabytes on the hard drive. The program installs inside the Master Boot Record (MBR), so that it will run every time the computer starts.
