tomsrtbt bootable from usb floppy
Not sure if this project is still active.
Several years ago, there were some posts about wanting to be able to boot a tomsrtbt from usb floppy. I didn't see any definitive answer although many suggestions. I made a working one recently, based on kernel 2.2.26.
It boots ok from my TEAC FD-05PUB via an uhci controller. I had to make several mods to the linux kernel (both in usb-uhci and in the ramdisk load init) and also change the tomsrtbt settings (settings.s and the lilo boot parms) to suit a removable scsi device.
If anyone else still interested after all these years, ask and I can provide more information.
unregistering / registering IF by hdparm - kernel prereq?
I am new to this. I have a laptop (IBM thinkpad) with ultrabay, and have a floppy drive and hard-drive-adapter which it can accept. I'd like to be able to hotswap them in and out as Windows can. I am running RH9 with a 2.4.20 kernel. I build hdparm 5.5 and after unmounting all partitions on my /dev/hdc, I tried
hdparm -U 1 /dev/hdc
(Based on the code in the contrib/idectl)
attempting to unregister hwif#1
but I can't pull the drive adapter and e.g. dd can still read the partitions. I assume it was not successful.
Do I need a newer kernel? 2.6.?
Also, I believe there is a bug in the contrib/idectl: it has
This looks the wrong way round to me, e.g. my dmesg says:
ide0: BM-DMA at 0x1860-0x1867, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0x1868-0x186f, BIOS settings: hdc:DMA, hdd:pio
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
