Today I faced a situation I'm not clear how to try to get around. I will have to perform a maintenance operation on a pair of Win 98 computers weekly. In that operation I will need to input and output data, so the preferable option is to install USB drivers (currently not installed) and then work always through USB from inside Windows. Both workstations are old have about 10 years old motherboards. Sorry in advance for long introduction.
When I wanted to install USB drivers I realised that one of them's optical drive does not work. I have no diskettes. I tried to boot from a Hiren's Boot USB flash drive. One of them went perfectly: enabled USB boot, flash drive showed under "Hard Disks" (xD), set flash drive with first priority, booted into it. But exaclty the one which optical drive is broken fails to do that: boot from USB option is enabled, flash drive shows as Hard Disk, but when it tries to boot form it screen says: "Boot failure.", then boots from HDD.
In which direction should I go to try to solve this? The real question is: if that motherboard was intended to boot from USB device, what has changed about motherboards internals since the last ten years about the issue? Have the number of different USB device interface grew and may an old motherboard not recognice a particular flash drive (so I should try another flash)? May be a architectural limit in the motherboard when it comes to handle an 8GB flash drive (so I should try a smaller one)? Have the types of boot sectors formats evolved in the last years (so I should choose a different boot sector type when I create the bootable Hiren's flash)? Is there any other important point about USB interfaces internals I am missing?
I'd love to find someone that could provide good references or increase my aknowledge about the issue. Best regards.
